Use the PB2 port tied to +3.3V after a RESET. This will kick in the HID Bootloader (even with anything written previously). One also can unplug the USB, tie PB2 to +3.3V, and plug it to the USB port, this also can kick in the HID Bootloader.
Very useful video, thank you. I solved my bootloader problems with two different STM32 boards within a couple of minutes. Especially the links in description are very useful: all are valid and get the right things I needed. Perfect explanation why and how. Many, many thanks!
I also solved my bootloader problem but what i found out later is that the usb comminication gives trouble with my serial3 connection to my blue tooth module, every time it looses connection with the pc and i have to upload the bootloader again. Do you experiance the same?
No worries, happy I could help. This UPDATE'S bootloader is a lot more user friendly than my other videos bootloader so it needed to be done. Have fun!
Thank you very much for your guidance. Spent 1.5 days to make STA32 working until I saw your video. Now I am good now. Just FYI, I used STM Flash Loader to flash bootloader and in the Arduino's Upload method I used HID Bootloader 2.2
Thanks for this! I already had a pile of these lying around, but I haven't used them due to programming being fiddly. Ordered 10 more and will be flashing the new bootloader on all of them.
Best stm32 bootloader tutorial out there! Question: I have a "Pill" board that is the same as the F103 however it has an F303 chip on it. The binaries you reference don't have an entry for the F303. Can I use the F103 bootloader binary? TIA!
@@CalebMarting Hi Great Vids however after 5 attempts I still get the following error when I try and down load a program : > Searching for [1209:BEBA] device.... Error - [1209:BEBA] device not found
@@johnmmcguinness7982 Do you still have this error? If so try flashing the bootloader and uploading any sketch. Before you upload the second time select the boards com port (that would be com 7 for you) in the Arduino IDE and then click upload. It should work this time
I had tossed 5 blue pill boards in a drawer after wrestling for days to get them to work with Platform.io back in 2018. I recently got interested in using them with DIY Eurorack synth modules. This procedure & the new bootloader did the trick, even with counterfeit CKS32F103C8T6 microcontrollers on the boards! Thanks for the update!
Amazingly simplified Video ever made , I came across ....You are a real Gem knowledge sharing sole ! Keep doing your good work for the community ! is there any similar video for STM8 boards I can refer ?
The first time I uploaded a bootloader it took about 15 hours to figure out how to do it. That's why I started making these, to save people time. Glad it works!
Nice! I was able to program my Blue Pill a while ago then something happened and I just kept getting errors. This video inspired me to clean up my IDE and set everything up again. By following your instructions I was able to get it all working again. Now I need to see if I can program a little 32F030F4P6 board I got a while ago.
@@CalebMarting Last night I opened up Serial Monitor WHILE uploading a sketch and the Bluepill could no longer be recognized as a usable USB device on ANY computer so I went through the process in this video again and now it works.
It's possible that something got messed up, or a setting wasnt set correctly. apparently you can set the boot and one jumper to the one position and that should force the bootloader to start when you press reset. Then you can see if the USB device is recognized
No, The HID bootloader is essentially a sketch that can store more sketches alongside of it. it will run the hid bootloader to start and then it'll start running your uploaded code. because that hid boot loader is always running you won't ever need to move boot zero
Hey. I know this is an older-ish video, but do you know if you can program the blue pill with STMCube IDE? Or with STlink utility or STM Cube Programmer. I just want to upload what I code in the IDE to the board via USB, be it directly or writing the binary file.
You could use the command line hid interface to upload bin files directly, though I'm not entirely sure how to do that. It's in the same repo as the the bin file
hello, not long ago I got the Blue Pill F103C8T6, and I am about to buy an ST LINK V2, but I am not sure what is a Bootloader ? Further I have heard something about decreasing the STM32's capacity. Does the bootloader mean you can use the board with the USB ?
I would definitely recommend buying the Stlink, it is worth it. The bootloader let's you upload arduino code over the USB, instead of needing an external programmer. However a bootloader will use 2kB of memory. An ST-Link v2 let's you program easily and debug your code. Also, you can still use the USB for serial output even if you are using an ST-Link, you just can't upload code over the USB without the bootloader. One more thing, if you are using a bootloader and upload code with an Stlink it will overwrite the bootloader and you'll have to reupload it If you want to use it again Hope this helped
I am a starter with micro controllers and your video was a great help. But because time goes by I faced the same problems as many people here: after first successful flash from Arduino all later flashes needed the bootloader pin 1 to set. After many hours of research, try and fail, I finally found the solution! I downgraded the version of STM32 core down from 1.9 to 1.8. STM32 core 1.9 and bootloader 2.2.2 may not be compatible, idk. Now I can upload the same reliable and repeatable way as before with Arduino nano.
//Edit: I was able to update core to 1.90. Maybe the root of my problem was solved by installing a driver for STM32 device. My system recognised the pill as a generic serial device that helps Arduino when searching for it.
Ah so COM ports are not required for uploading code, but Arduino complains when there is one on your system and you don't have one selected. Maybe that was the root of your problem
@@CalebMarting yes, but before Installation of the driver the system was not able to recognize the blue pill at all, every time after first flash from Arduino. To be complete here, the device is now a serial device and the port in Arduino fits to it.
What happens when I am going to use more than 1 blue pill? I have 2 blue pill. 1 is working good but 2 is not recognized by the PC. I did not miss any of the steps mentioned above.
Thank you for video! ...the issue is that the new STM32 core package produces larger images than the "old" one... So, might be critical for large applications that utilize almost all flash memory; could happen it would not be enough memory to flash a re-compiled app... Also, you do not need Cube to flash bootloader using STLink. You may use STLink utility (available at ST.com) to do it...
Great video Caleb! build_flags = -D PIO_FRAMEWORK_ARDUINO_ENABLE_CDC -D USBCON -D USBD_PID -D USBD_VID=0x0483 -D USB_MANUFACTURER="Unknown" -D USB_PRODUCT="\"BLUEPILL_F103C8\"" -D HAL_PCD_MODULE_ENABLED NOTE: -D USBD_PID was required, if you look at the error it's obvious, but that should work as of me typing this.
Caleb Marting asked you which library for RSA encryption you recommend me to be compatible with a PHP code and the arduinoST I have tried some but they are for AVR and do not work well with the ST, thank you very much
If you want it to work no matter what platform, you could use a C/C++ library. That way there is no hardware dependency. Something like this maybe: github.com/andrewkiluk/RSA-Library Let me know if that works
Worked for me! I've never done any microcontroller work and got a bluepill (against advice of the interent) to get started. This tutorial was easy to follow and I got everything working and the example code prints to the serial monitor. Thanks! I'll subscribe too see what else you do with the blue pill.
Is there an update to this video? Perhaps a an updated link to proper files? Have tried (and tried) using updated links below But no luck. Boot loader uploads fine. But when I go to program vis USB (HID 2.2), sez it can't find the board. Thx ...
Thank you for this video. My question is whether, after I install this bootloader using the method you describe, will I be able to then compile and upload a sketch that requires the dan brown board manager? What do you think?
Thank you for this tutorial. I could make it work under Linux (XUbunut 18.04) but I have some remarks: $ uname -a Linux mybox 4.15.0-99-generic #100-Ubuntu SMP Wed Apr 22 20:32:56 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux - The STM32 Cube Programmer doesn't work here under Linux but I could flash the HID bootloader binary without problems using the st-flash utility via my ST-Link clone.

"Timeout error occured while waiting for acknowledgement. Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again..." how to overcome this problem?
There's a couple possibilities. What causes that error is that your set up for serial upload is wrong. For instance If you don't have the boot zero jumper in the one position and press reset, etc. If you are sure that is all correct, try another blue pill if you have it, sometimes boards just don't work cause defective products still make them money
I cannot get this to work on OSX 10.14.6, used STM32Progammmer to do 'Full Chip Erase' then burned hid_generic_pc13.bin. I get the rapid flashing led but it doesn't work from the IDE Searching for [1209:BEBA] device... It's not showing as a USB device with "ioreg -p IOUSB -l -w 0" or "lsusb", other than "Apple Internal Keyboard / Trackpad" I've tried 3 or 4 some with the resistor fix and some without and different usb cables. Spent hours on messing with this without success, any hints?
I'm sorry but sometimes hardware is just finnicky... You can turn one of your blue pills into an ST-Link v2 and program/debug with that, which works pretty well. If you want to join the discord linked in the description I can walk you through how to do that
Unfortunately you can't use ST-Link for serial, however you can still output serial over the USB port. You can have the ST link and the board plugged in at the same time, just don't plug in the 3.3 volt line from the ST link
No worries, I don't know, typically that doesn't happen to me. You can try uploading the bootloader again, and if you want try doing a full chip erase using the cube programmer and then uploading the bootloader again. Also check to see if your chips are a knock off, they might say CKS or something instead of ST
Thanks for info but in my case after installing the bootloader when i plug my STM32f103 bulepill it says USB not recognized and in arduino IDE it says your board is not connected,but i think bootloader is flashed as mine PC13 led is blinking at very high rate.Any ideas?
Old but after you flash the bootloader you need to hook it back up to the TTL converter and select the COM port and then try uploading in arduino IDE. It then begins to flash something else and it will finally work.
Followed this and was able to program the 2.2.2 HID bootloader onto a bluepill. It was attached to my linux box and I was able to program it using arduino as described. I was able to upload the blink sketch and it worked fine. What I noticed was that after programming the bootloader and plugging in the device I saw Feb 19 17:35:17 x1-Carbon kernel: [159760.782737] usb 1-4.3: new full-speed USB device number 62 using xhci_hcd Feb 19 17:35:17 x1-Carbon kernel: [159760.896087] usb 1-4.3: New USB device found, idVendor=1209, idProduct=beba Feb 19 17:35:17 x1-Carbon kernel: [159760.896088] usb 1-4.3: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Feb 19 17:35:17 x1-Carbon kernel: [159760.896089] usb 1-4.3: Product: STM32F HID Bootloader Feb 19 17:35:17 x1-Carbon kernel: [159760.896090] usb 1-4.3: Manufacturer: www.serasidis.gr Feb 19 17:35:17 x1-Carbon kernel: [159760.897242] hid-generic 0003:1209:BEBA.002A: hiddev0,hidraw4: USB HID v1.11 Device [www.serasidis.gr STM32F HID Bootloader] on usb-0000:00:14.0-4.3/input0 Subsequent upload required the tty port to be set to ttyACM0, which I found strange but then I noticed that when attached it showed up as a different device.

All works fine, but I thought it was strange that the device idVendor changed from 1209 to 0483 ? Looks like newer version of the STM package (1.9) in arduino overwrote the HID bootloader.
It could also be the fact that when you upload an Arduino sketchwith the settings I describe in the video it creates a serial port. It's possible that's what you're detecting since that isn't initially available when you first upload the bootloader
Im getting “data read fail”, “GetID command not acknowledged” and “read protection” errors on the stm32cube software on all my 5 blue pills, despite it reading the chip information just fine. Any clues as to what may be happening? Great video regardless.
Very cool, Im more curiouse to know how a bootloader works what it does and why hasnt stm32 done this for convenience? On the otherhand im flashing fine on my stm32 clone(ch32) through its usb port without an additional bootloader although i have to use their tool for flashing. But after all that i found the stlink actually more convenient since i dont have to unplug and reset jumpers everytime like i have to with usb. Its a miracle i havent lost the jumpers the amount of time its popped out on its own while trying to take it out, its not a matter of if, but when...
Caleb Marting, First thanks for you nice video's. I am a NOOB and have used your guide with Win10, STM32F401, I am using the ST-Link V2 with the latest firmware. My question, is the HID method with the STM32F401 board is not listed under the Binaries I downloaded, it has the STMF103 and the STMF407 but not the F401's. Is there a binary file you can point me to for the correct HID files, I have versions 2.2.2 from the github. I have not been able to get the board to function, When I started, the on board led was blinking and the red led was on, now after trying the STM Cube Programmer to load the binary F407, it just showing the red power light now. I have moved the boot switch to the correct position and after STM cube indicated a download complete, I move the boot switch back to its original position. any pointers appreciated Thanks.
Another common problem for Mac user (I know how you feel), if you have tried everything mentioned in the video and it says something like the COM port is busy, try changing the USB-C port with another one. Sometimes it just works.
It seems to still require a port even in HID 2.2 bootloader. Ill try downgrading arduino IDE. Otherwise everything else I followed and it worked. Maybe usb cable.
Hi Your video on STM32F103 is brilliant, it helps a lot. Both programming and native are combined into 1 port after installing the HID bootloader. Appreciate your video. Do you also have a video that guide us on STM32F407 board?
It should be almost exactly the same process, just using the f407 bootloaders instead. I've never used one of those boards though. What are you confused on?
Even though I had uninstalled all smt32-related stuff from the UI, I still had in the `C:\Users\MyUser`Documents\Arduino\Hardware` some folder called Arduino_SMT32-master that I surely put there some day in the past from some other method. That's also the reason why my UI in "Tools" looked different than the one showed by Caleb. Once I deleted the folder, my UI started looking normal again and I was able to select all the right options that he showed. Finally, I had to manually select the right COM port at the time of my second upload and that was it now my Blackpill f103C8T6 works perfectly as the Bluepill shown in the video.
Do any devices show up in the device manager when you plug it in? That's very interesting. Try moving the boot one jumper to the one position and seeing what happens
@@CalebMarting Sorry I edited my comment to make it more concise after I found my mistake, I think you answered to the original one. However... now I tried uploading my own sketch instead of a simple led+Serial and I've lost the COM port that had appeared and I'm unable to program the Blackpill again (the "1209:BEBA" error).
@@CalebMarting I found why my sketch did that: "Wire.setClock(400000L)". Apparently that's the cause. When I don't have it, my bootloader continues working for another round.
Important to be persistent with this, I used the usb SWD programmer, stlink v.2 to flash, simply because it was convenient, and I had to finally erase it three times, and then program twice in succession, to get the new HID 2.2.2 bootloader to enumerate correctly on Window 10. Be sure to use a known good usb cable, and I had to use my older 2.0 version USB connector, not my new USB 3.0 ports I added via a PCI-e expansion card Once you get past the initial flash, it will create a serial port that works perfectly as a CDC serial port (COM44 in this particular case). I also tested the hid_flash (v2.2) from the command line like this ... "hid_flash>hid-flash.exe C:\Users anda\AppData\Loca\Temp\arduino_build_363784/Serial_Test_Arduino.ino.bin COM44" All OK! (As always, don't be shy to connect/reconnect the usb cable to power cycle, and/or press the reset button if something appears to hang)
I'm not sure, someone else was trying the f303 and couldn't get it to work with this or with my f401 video. I would recommend getting an ST link V2, it's well worth it
I think It uploads fine The first time without a com port selected for me, but then I have to have it selected too. I think the reason is Arduino has an old check that makes sure there's a com port selected when uploading because It was designed for the AVR chips that upload over com
You can probably set it up but I haven't seen anyone get that working yet. You'd basically need to have a script that runs for upload when the binaries are generated. Again I'm sure it's possible. I would recommend an ST Link V2 if you actually want to use STM32 cube IDE
You can go back to the old core mentioned in my previous video on the topic, although I don't know if you'll be able to use this specific bootloader then
Although I think it is possible to use it as a keyboard and or mouse if you set the USB in the tools menu to hid and use the built-in keyboard or mouse library
I have an error at the connection process with ST-LINK V2 via STM32 Cube Programmer : "OLD ST-LINK firmware, please upgrade it befrore trying to reconnect". And when i click the upgrade firmware button this appears "ST-LINK is not found in DFU mode. Please restart it." Any idea how to fix it?
I think when it says "please restart" just unplug and replug the ST-Link and try again. You may have to be quick but I don't believe it matters, it should lock it in DFU mode
We had an issue like this before on the discord.If you want to join I can help you figure it out there (link in description) otherwise how he fixed it was copying the downloaded hid flash from GitHub into where it expects it in the Arduino15 folder (I forget exactly what subdirectory though)
I've been playing with the Blue Pill and the St-Link Flash utility, and I think I might have erased chip including the built-in embedded boot loader.. is that possible? The reason, when I switch the BOOT0 jumper to 3.3v and power the board, I see the UART1 TX pin from the Stm32 stay LOW... but I've read that if the ROM bootloader is running correctly, its TX line output should idle HIGH. I tried sending 0x7F (even parity) anyways, but no luck.. no (0x79) response from the chip on UART1 (B7/B6). I also tried UART2/3 (A3/A2, B11/B10). Is there a way to verify if the embedded bootloader is still there.. or restore it if I've clobbered it? As a test, I was thinking jumping to the bootloader from my application but I can't find the address where to jump. AN2606 says the for medium density devices like the F103C8, that the chip id is 0x410, but only lists the *bootloader id*/address (0x10/0x1FFFF7D6).
The UART bootloader is in rom and cannot be erased. However the chip itself could be fried for some reason. Do you have an ST link or another blue pill? You can make the blue pill into an ST link and potentially still upload code to the one that's messed up. I should have a video coming out about that soon
@@CalebMarting yes, the chip seems to operating otherwise normally.. I can still program it with the st-link (swd interface). Long-shot, but perhaps it is in DFU mode, but somehow thinks the upgrade is coming from USB/CAN/I2C/SPI and therefore its disabled the uart? Seem unlikely as aside from power via the usb-micro, all the other pins are open.. but not sure what else to make of it!
Those pins might have just been fried too cuz I've heard other people have fried only specific pins. Very weird. Perhaps there's some sort of protection feature? Maybe you could use STM32 cube programmer to do a full chip erase, see if that helps
@@CalebMarting Thanks, you gave me a great idea.. test the pins by writing a program that uses UART1... as I was doing that, the Device Configuration Tool shows UART1 to be on P10/P9! Using those pins, the DFU worked! I goofed when I was using a very colorful popular pinout diagram of the blue pill that shows RX1/TX1 on B7/B6..I thought the outer most columns were the default pins, and alternate functions on the inner ones... apparently, that's not the case!
Hi - thank you for these videos - very helpful! I hope you can find the time to help me - I bought some STM32 boards that seem to be using this chip: STM32F303CCT6 with 256 KB Flash - Robotdyn is the manufacturer. The binaries in the links you posted are for F103 and F407 only - does this mean my board cannot be flashed with a bootloader?
Hello! The f303 supports DFU upload, so you actually do not need a separate bootloader to upload code over USB. you can find this info in section 3.5 of the official datasheet. www.google.com/url?sa=t&source=web&rct=j&url=www.st.com/resource/en/datasheet/stm32f303cb.pdf&ved=2ahUKEwiv95CQ3LbqAhVGCc0KHQieDuoQFjAAegQIBRAC&usg=AOvVaw316i_atPeBiw5Z2kVGDzC4&cshid=1593973002676 Please take a look at my black pill video, the process is essentially the same for uploading code! ruclips.net/video/b1123kz_3MM/видео.html
@@CalebMarting Thanks for the prompt response! I cannot get my Windows 10 PC to "recognize" the STM32 board, hence why I thought I needed to flash the bootloader. Is this just a USB driver issue then, and if so do you know where I can find the correct driver?
I'm running into a weird issue with PlatformIO! I can upload the code to the BluePill but only once than the laptop says "USB device not recognized", if I re-flash the bootloader then I can upload the code again but right after that get the "USB device not recognized" error. To get to upload from PlatformIO all I had to do was add "upload_protocol = hid" in the .ini file.
There's a lot of options that aren't checked when you use platform IO because there's no gui. Go to 8:30 in the video and I have a config that works ruclips.net/video/Myon8H111PQ/видео.html
I have problems !, I get this comment:"Timeout error occured while waiting for acknowledgement. Timeout error occured while waiting for acknowledgement. Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again... "
Do you still have this error? If you do I can walk you through a fix. If you join the discord (link is in the description) it would make it a lot easier to show you how to fix it.
EDIT: Okay, I found out how to fix that! In my case it was bad, cheap chineese clone of programator PL2303. If you have one of these, you need to find drivers from 2008 (3.3.2.105). They will work on Windows 10. The new ones just block the chineese versions from working. Aside from that, check all the cables if they stick, and don't forget to choose the correct port, in Cube32Programmer in UART configuration, check if other COM ports appear :)
static.leaflabs.com/pub/leaflabs/maple-docs/0.0.12/bootloader.html This page says you need to tie pin 2 to ground (boot 0) and in the process would be the same. Although I believe the maple mini comes with a bootloader, and you may want to use their official bootloaders as well
For some reason this works only the first time I upload a sketch after the bootloader was installed. Once the sketch is uploaded in Arduino IDE (PlatformIO as well) I get "Error - [1209:BEBA] device is not found" on all subsequent upload attepmts. The only fix is to upload the bootloader again through STM32CubeProgrammer. What I'm missing?
You need to have the correct USB settings as mentioned in the video, such as Usb support. Also if your Sketch us using HID you can get some interference. If you move the boot1 jumper to the one position and press reset, it will put it in bootloader mode and you should be able to upload again.
@@CalebMarting Thanks for answering - yep, the bootloader starts when boot1 jumper is in position one. However I cannot get it to work (after the first upload) in position zero for both jumpers.

Am i the only one who cannot communicate with bluepill over uart? No matter what i tried, it didnt work. I checked A9 and A10 if they are connected to stm chip with multimeter and yes they are. When it is not bootlader mode it just blinks, when it gets bootloading state no respond at all.
It didn't work for me, when I upload the bootloader and reset the board, the led on pc13 blink pretty fast. Then I tried to upload a sketch and didn't work.
I mean it could be a USB cable without data lines, is any device detected when you connect it? The LED blinking means it should be working. You could also try it on another blue pill because sometimes it'll look like it should work but it just won't
After you flash the bootloader you need to hook it back up to the TTL converter and select the COM port and then try uploading in arduino IDE. It then begins to flash something else and it will finally work.
// This method did not work for me, I was able to finish the process and load the "Blink" example, but after loading my own code, the PC did not recognize the blue pill board. I have resorted to your previous video (2018), and the previous method has worked for me wonderfully.
Try again but with 1.8 of core and not 1.9. This worked for me. //Edit: I was able to update core to 1.90. Maybe the root of my problem was solved by installing a driver for STM32 device. My system recognizes the pill as a generic serial device that helps Arduino when searching for it.
I possibly had the same problem: My Bluepill could send messages via serial over ttyACM0 but it was not possible to flash it a second time. The bootloader was not active anymore (no fast blinking), but the slow blinking occurred according to the example I had programmed. The Solution was to reset the board (or power it up) while the BOOT1-jumper was set to 1. The other jumper! Then the fast blinking reoccurred and I was able to flash it with HID Bootloader method. After resetting I could set the Jumper back to 0. Thus after reprogramming the board the USB-Serial automatically re-activated. Perhaps this should be added to the instructions. Now I'm very happy with the solution: Small bootloader and defined switching to programming via jumper. No STLink or USBtoSerial adapter needed anymore. Many Thanks Caleb.
I have tried this and ran into a brick wall when I could not get a CONNECT when clicking on the green button in the STM32CubeProgrammer. I am using a ST-Link32/V2 clone which had been working fine until today. I didn't change anything, but I can no longer program my blue pill with it. I am on W10 and it recognizes the dongle as does STM32CubeProgrammer, which does read the serial number of the dongle. Does anyone have any ideas of how to get this bootloader onto my blue pill? Thanks!
i cant find my st link dongle and i dont have a serial adaptor, i do have a lot of nanos' megas and wemos bits and even something labeled usb asp.......
I haven't quite figured out how to use another mcu as a serial adapter to program, but if you can find a sketch that lets you do it, please let me know! It certainly seems possible but I don't know the speeds
...I recently got 2 pcs of the infamous bluepill...but both had different chip Id by country..1st one chn other mlys ..both did not work with ftdi..later The mlys worked with stlink ..later on ftdi after pc13 bootloader install..but the chn came with 128kb of uneraseable bootloader detected under hotplug cube programmer.only..normal mode get no target...how to fix it..?
Is it the latest java version? In the installation directory there were some files that look like you could use them for command line. I bet you could use those to install. otherwise there are specific tools that STM has put out for just the ST link or serial port. (STM flash loader demonstrator for that one) although you will still need to have those command line things installed
We found two causes for this 1. Defective/knockoff chips 2. Failed upload To fix the 1st, try a different blue pill board, they're so cheap that you should probably just buy them in pairs or triplets. To fix the second, perform a full chip erase in stm32 cube prog and then upload again. You can try it one or two times. More often than not we found it happens with defective chips but it can't hurt to try uploading again after a full erase. We can provide more info in the discord linked in the description

![Installing the STM32 USB Bootloader, Easily! [SEE DESCRIPTION]](/img/1.gif)
After a full day of trying to get my ST32 to work, you came in clutch. Thank you so much!
Use the PB2 port tied to +3.3V after a RESET. This will kick in the HID Bootloader (even with anything written previously). One also can unplug the USB, tie PB2 to +3.3V, and plug it to the USB port, this also can kick in the HID Bootloader.
Very useful video, thank you. I solved my bootloader problems with two different STM32 boards within a couple of minutes. Especially the links in description are very useful: all are valid and get the right things I needed. Perfect explanation why and how. Many, many thanks!
I also solved my bootloader problem but what i found out later is that the usb comminication gives trouble with my serial3 connection to my blue tooth module, every time it looses connection with the pc and i have to upload the bootloader again. Do you experiance the same?
How ironic that you uploaded this UPDATE on the very day I was researching how to do this. Thanks for making an UPDATE!
No worries, happy I could help. This UPDATE'S bootloader is a lot more user friendly than my other videos bootloader so it needed to be done. Have fun!
this video is amazing on so many levels , liked and subbed.
This is one of the best videos for this, I appreciate the clean look and sound of the video as well.
Thank you! Glad you enjoyed
Agreed, if windows doesn't recognize the bluepill just unplug it from power and plug it again several times, it will work.
wow ,looks like the folks over at STM finally got it together and realized Arduino is here to stay. THANKS
Thank you very much for your guidance. Spent 1.5 days to make STA32 working until I saw your video. Now I am good now. Just FYI, I used STM Flash Loader to flash bootloader and in the Arduino's Upload method I used HID Bootloader 2.2
Thanks for such a clear and concise video. First time I've got a blue pill bootloader to work!
Glad it helped!
Great video! Explained a lot of the basics that other videos skipped over.
Thanks for this! I already had a pile of these lying around, but I haven't used them due to programming being fiddly. Ordered 10 more and will be flashing the new bootloader on all of them.
Sounds awesome! I am amazed at how well this bootloader works so happy to spread the news. Best of luck!
Best stm32 bootloader tutorial out there! Question: I have a "Pill" board that is the same as the F103 however it has an F303 chip on it. The binaries you reference don't have an entry for the F303. Can I use the F103 bootloader binary? TIA!
Thank you, just saw this on reddit, the day after i got the board. Subscribed!
Good timing then. Thank you!
@@CalebMarting Hi Great Vids however after 5 attempts I still get the following error when I try and down load a program : > Searching for [1209:BEBA] device.... Error - [1209:BEBA] device not found
Further to my last Windows device manager reports device on Comm 7 but bootloader is checking comm 5.
@@johnmmcguinness7982 Do you still have this error? If so try flashing the bootloader and uploading any sketch. Before you upload the second time select the boards com port (that would be com 7 for you) in the Arduino IDE and then click upload. It should work this time
Thank you very much. Worked like a charm!
This is fantastic. Thank you so much!! I have updated the boot-loader on all my STM32 boards!
Awesome! Glad you found it useful
I had tossed 5 blue pill boards in a drawer after wrestling for days to get them to work with Platform.io back in 2018. I recently got interested in using them with DIY Eurorack synth modules. This procedure & the new bootloader did the trick, even with counterfeit CKS32F103C8T6 microcontrollers on the boards! Thanks for the update!
Thank you! I have a couple of CKS ones as well and they worked fine as well with this. I wonder what doesn't work though lol
tHANK YOU VERY VERY SO MUCH!! yOU ARE THE ONE!! Including Serasidis of course (The Greek One)!!!
Thank you!
Amazingly simplified Video ever made , I came across ....You are a real Gem knowledge sharing sole ! Keep doing your good work for the community !
is there any similar video for STM8 boards I can refer ?
I haven't used any STM 8 boards so I'm not sure, if you need any help though I'm sure the process is similar
thank you for your video, now my 'Blue Pill' work well with Arduino, and serial output it's great to help to display info or debug.
Great job.
You just saved me about 15 hours work! thanks Sooo much man.... works first time, exactly as you have described.... cheeeers!
The first time I uploaded a bootloader it took about 15 hours to figure out how to do it. That's why I started making these, to save people time. Glad it works!
Nice! I was able to program my Blue Pill a while ago then something happened and I just kept getting errors. This video inspired me to clean up my IDE and set everything up again.
By following your instructions I was able to get it all working again.
Now I need to see if I can program a little 32F030F4P6 board I got a while ago.
Good luck! Glad it worked
@@CalebMarting Last night I opened up Serial Monitor WHILE uploading a sketch and the Bluepill could no longer be recognized as a usable USB device on ANY computer so I went through the process in this video again and now it works.
It's possible that something got messed up, or a setting wasnt set correctly. apparently you can set the boot and one jumper to the one position and that should force the bootloader to start when you press reset. Then you can see if the USB device is recognized
@@CalebMarting OK. If it happens again I'll set both jumpers and reset to see if it works.
Re-flashing the bootloader isn't difficult anyway.
Thanks a lot. I got my first stm32 project.
Thanks for the video. One question, with HID bootloader, do you still need to move the boot0 jumper each time when uploading the sketch?
No, The HID bootloader is essentially a sketch that can store more sketches alongside of it. it will run the hid bootloader to start and then it'll start running your uploaded code. because that hid boot loader is always running you won't ever need to move boot zero
Really loved the way you included more or less subtle references to things in the previous video. Like the tweezers thing. :D
"subtle" may be the wrong word for it :p
@@CalebMarting "more or less" :)
":)"
Hey. I know this is an older-ish video, but do you know if you can program the blue pill with STMCube IDE? Or with STlink utility or STM Cube Programmer. I just want to upload what I code in the IDE to the board via USB, be it directly or writing the binary file.
You could use the command line hid interface to upload bin files directly, though I'm not entirely sure how to do that. It's in the same repo as the the bin file
@@CalebMarting Thanks! I'll check it out
Great video man. I have a question. will this also work with cube programmer? I mean can I flash .bin files with cube programmer using the USB?
Unfortunately it will not. It won't recognize anything but the default bootloaders on the chip, the ones in ROM
hello, not long ago I got the Blue Pill F103C8T6, and I am about to buy an ST LINK V2, but I am not sure what is a Bootloader ? Further I have heard something about decreasing the STM32's capacity. Does the bootloader mean you can use the board with the USB ?
I would definitely recommend buying the Stlink, it is worth it.
The bootloader let's you upload arduino code over the USB, instead of needing an external programmer. However a bootloader will use 2kB of memory. An ST-Link v2 let's you program easily and debug your code. Also, you can still use the USB for serial output even if you are using an ST-Link, you just can't upload code over the USB without the bootloader.
One more thing, if you are using a bootloader and upload code with an Stlink it will overwrite the bootloader and you'll have to reupload it If you want to use it again
Hope this helped
When adding board i get the "depreciated please use new package index stm32 cores"
If I upload a bootloader in stm 32. After uploading does I still need a programme or st link to program the board. I new with mcu's. So please clear
this was awesome :) works with mac too after installing stm32cubeprog for mac
That's why I love the HID bootloader so much more. No drivers and it just (usually) works
very cool, i had so much trouble with this in the past
I am a starter with micro controllers and your video was a great help.
But because time goes by I faced the same problems as many people here: after first successful flash from Arduino all later flashes needed the bootloader pin 1 to set.
After many hours of research, try and fail, I finally found the solution!
I downgraded the version of STM32 core down from 1.9 to 1.8.
STM32 core 1.9 and bootloader 2.2.2 may not be compatible, idk.
Now I can upload the same reliable and repeatable way as before with Arduino nano.
//Edit: I was able to update core to 1.90. Maybe the root of my problem was solved by installing a driver for STM32 device. My system recognised the pill as a generic serial device that helps Arduino when searching for it.
Ah so COM ports are not required for uploading code, but Arduino complains when there is one on your system and you don't have one selected.
Maybe that was the root of your problem
@@CalebMarting yes, but before Installation of the driver the system was not able to recognize the blue pill at all, every time after first flash from Arduino. To be complete here, the device is now a serial device and the port in Arduino fits to it.
What happens when I am going to use more than 1 blue pill? I have 2 blue pill. 1 is working good but 2 is not recognized by the PC. I did not miss any of the steps mentioned above.
Is this tutorial to use stm with Arduino IDE, or to use it with stm cube and cube programmer via usb?
Thank you for video! ...the issue is that the new STM32 core package produces larger images than the "old" one... So, might be critical for large applications that utilize almost all flash memory; could happen it would not be enough memory to flash a re-compiled app...
Also, you do not need Cube to flash bootloader using STLink. You may use STLink utility (available at ST.com) to do it...
Great video Caleb!

The way you address the comments section is hilarious!
Caleb Marting asked you which library for RSA encryption you recommend me to be compatible with a PHP code and the arduinoST I have tried some but they are for AVR and do not work well with the ST, thank you very much
If you want it to work no matter what platform, you could use a C/C++ library. That way there is no hardware dependency. Something like this maybe: github.com/andrewkiluk/RSA-Library
Let me know if that works
Worked for me! I've never done any microcontroller work and got a bluepill (against advice of the interent) to get started. This tutorial was easy to follow and I got everything working and the example code prints to the serial monitor. Thanks! I'll subscribe too see what else you do with the blue pill.
Is there an update to this video? Perhaps a an updated link to proper files? Have tried (and tried) using updated links below But no luck. Boot loader uploads fine. But when I go to program vis USB (HID 2.2), sez it can't find the board. Thx ...
Thank you very much very good your tutorial worked perfect you unless my stm32 do not go to the trash
Thank you for this video. My question is whether, after I install this bootloader using the method you describe, will I be able to then compile and upload a sketch that requires the dan brown board manager? What do you think?
I believe you can use the HID bootloader with the dan brown core but have not tried
Fabulous video, i am a fan of the blue pill.
hi, the cube programmer log says ST-LINK error (DEV_CONNECT_ERR) when i try to connect my st link, what do i do for it to connect successfully?
Thank you for this tutorial.
I could make it work under Linux (XUbunut 18.04) but I have some remarks:
$ uname -a
Linux mybox 4.15.0-99-generic #100-Ubuntu SMP Wed Apr 22 20:32:56 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
- The STM32 Cube Programmer doesn't work here under Linux but I could flash the HID bootloader binary without problems using the st-flash utility via my ST-Link clone. I did this outside of the Arduino IDE, it was as simple as "st-flash write hid_generic_pc13.bin 0x08000000" on a blank Blue Pill
- The udev rule configuration for proper detection of the HID bootloader as described on the bootloader github should be in place and active before opening the Arduino IDE.
- The created virtual COM port seems to jump back and forth (/dev/ttyACM0 and /dev/ttyACM1) if the reset button is pressed or the cable is reconnected.
- Using the virtual COM port works only after the flashing. One cannot open the COM port and flash in parallel, e.q. open the serial monitor later. It may even be necessary to change the COM port.
- I get kernel messages and error messages inside the IDE regarding the COM port.

Thanks for the useful video BTW
"Timeout error occured while waiting for acknowledgement.
Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again..." how to overcome this problem?
There's a couple possibilities. What causes that error is that your set up for serial upload is wrong. For instance If you don't have the boot zero jumper in the one position and press reset, etc. If you are sure that is all correct, try another blue pill if you have it, sometimes boards just don't work cause defective products still make them money
The PIO instructions need another build flag for me: -D USB_PID=0x0100 was needed. Thanks
Is this bootloader version still the most current for STM32?
DUDE - Thank you so much!!!
I cannot get this to work on OSX 10.14.6, used STM32Progammmer to do 'Full Chip Erase' then burned hid_generic_pc13.bin. I get the rapid flashing led but it doesn't work from the IDE Searching for [1209:BEBA] device...
It's not showing as a USB device with "ioreg -p IOUSB -l -w 0" or "lsusb", other than "Apple Internal Keyboard / Trackpad"
I've tried 3 or 4 some with the resistor fix and some without and different usb cables. Spent hours on messing with this without success, any hints?
I'm sorry but sometimes hardware is just finnicky... You can turn one of your blue pills into an ST-Link v2 and program/debug with that, which works pretty well. If you want to join the discord linked in the description I can walk you through how to do that
@@CalebMarting I might try one of the other bootloaders or a different vendor, or stick with stlink v2. Is it possible use stlink for serial output?
Unfortunately you can't use ST-Link for serial, however you can still output serial over the USB port. You can have the ST link and the board plugged in at the same time, just don't plug in the 3.3 volt line from the ST link
Bro you are the king
sorry but one last question . Does the USB connection get disconnect and connect during the upload process ? please reply?
No worries, I don't know, typically that doesn't happen to me. You can try uploading the bootloader again, and if you want try doing a full chip erase using the cube programmer and then uploading the bootloader again. Also check to see if your chips are a knock off, they might say CKS or something instead of ST
@@CalebMarting thanks a lot ! man!!
Thanks for info but in my case after installing the bootloader when i plug my STM32f103 bulepill it says USB not recognized and in arduino IDE it says your board is not connected,but i think bootloader is flashed as mine PC13 led is blinking at very high rate.Any ideas?
Hey same problem here. Any fix?
Sometimes the boards themselves are just broken, try a new board. Other times your USB cable might not have data lines so try a new USB cable
Old but after you flash the bootloader you need to hook it back up to the TTL converter and select the COM port and then try uploading in arduino IDE. It then begins to flash something else and it will finally work.
you're the best! thank you
Followed this and was able to program the 2.2.2 HID bootloader onto a bluepill. It was attached to my linux box and I was able to program it using arduino as described. I was able to upload the blink sketch and it worked fine.

No issues uploading new sketches that blink or use the Serial.println() function. All works fine, but I thought it was strange that the device idVendor changed from 1209 to 0483 ? Looks like newer version of the STM package (1.9) in arduino overwrote the HID bootloader.
It could also be the fact that when you upload an Arduino sketchwith the settings I describe in the video it creates a serial port. It's possible that's what you're detecting since that isn't initially available when you first upload the bootloader
Will this work for flashing a Keil uVision project via USB? (not from the Arduino IDE)
I don't believe so... it could probably be set up but not easily, or worth the $2 of an ST Link V2
Im getting “data read fail”, “GetID command not acknowledged” and “read protection” errors on the stm32cube software on all my 5 blue pills, despite it reading the chip information just fine. Any clues as to what may be happening? Great video regardless.
Thank you for your great video! Can I use the same STM32 HID Bootloader 2.2.2 for an STM32F405RGT6?
Very cool, Im more curiouse to know how a bootloader works what it does and why hasnt stm32 done this for convenience? On the otherhand im flashing fine on my stm32 clone(ch32) through its usb port without an additional bootloader although i have to use their tool for flashing. But after all that i found the stlink actually more convenient since i dont have to unplug and reset jumpers everytime like i have to with usb. Its a miracle i havent lost the jumpers the amount of time its popped out on its own while trying to take it out, its not a matter of if, but when...
Caleb Marting, First thanks for you nice video's. I am a NOOB and have used your guide with Win10, STM32F401, I am using the ST-Link V2 with the latest firmware. My question, is the HID method with the STM32F401 board is not listed under the Binaries I downloaded, it has the STMF103 and the STMF407 but not the F401's. Is there a binary file you can point me to for the correct HID files, I have versions 2.2.2 from the github. I have not been able to get the board to function, When I started, the on board led was blinking and the red led was on, now after trying the STM Cube Programmer to load the binary F407, it just showing the red power light now. I have moved the boot switch to the correct position and after STM cube indicated a download complete, I move the boot switch back to its original position.
any pointers appreciated Thanks.
ruclips.net/video/b1123kz_3MM/видео.html I have a guide specifically for that chip
Another common problem for Mac user (I know how you feel), if you have tried everything mentioned in the video and it says something like the COM port is busy, try changing the USB-C port with another one. Sometimes it just works.
It seems to still require a port even in HID 2.2 bootloader. Ill try downgrading arduino IDE. Otherwise everything else I followed and it worked. Maybe usb cable.
Thank you from Brazil bro!
Np bro 😂
The Github link in the description is broken and not valid anymore.
Hi, will it work with other frameworks, such as stm32Cube?
Great job! Thanks You a lot. Finally easy un following story to do it properly! Thumbs up from me!
Yeah I tried to cover the edge cases and compress it a decent amount. Glad you found it useful!
Hi
Your video on STM32F103 is brilliant, it helps a lot. Both programming and native are combined into 1 port after installing the HID bootloader. Appreciate your video.
Do you also have a video that guide us on STM32F407 board?
It should be almost exactly the same process, just using the f407 bootloaders instead. I've never used one of those boards though. What are you confused on?
Even though I had uninstalled all smt32-related stuff from the UI, I still had in the `C:\Users\MyUser`Documents\Arduino\Hardware` some folder called Arduino_SMT32-master that I surely put there some day in the past from some other method. That's also the reason why my UI in "Tools" looked different than the one showed by Caleb. Once I deleted the folder, my UI started looking normal again and I was able to select all the right options that he showed. Finally, I had to manually select the right COM port at the time of my second upload and that was it now my Blackpill f103C8T6 works perfectly as the Bluepill shown in the video.
Do any devices show up in the device manager when you plug it in? That's very interesting. Try moving the boot one jumper to the one position and seeing what happens
@@CalebMarting Sorry I edited my comment to make it more concise after I found my mistake, I think you answered to the original one.
However... now I tried uploading my own sketch instead of a simple led+Serial and I've lost the COM port that had appeared and I'm unable to program the Blackpill again (the "1209:BEBA" error).
@@CalebMarting I found why my sketch did that: "Wire.setClock(400000L)". Apparently that's the cause. When I don't have it, my bootloader continues working for another round.
For STlink V2, which position should the jumper set during loading the hid library file?
Important to be persistent with this, I used the usb SWD programmer, stlink v.2 to flash, simply because it was convenient, and I had to finally erase it three times, and then program twice in succession, to get the new HID 2.2.2 bootloader to enumerate correctly on Window 10.
Be sure to use a known good usb cable, and I had to use my older 2.0 version USB connector, not my new USB 3.0 ports I added via a PCI-e expansion card
Once you get past the initial flash, it will create a serial port that works perfectly as a CDC serial port (COM44 in this particular case).
I also tested the hid_flash (v2.2) from the command line like this ...
"hid_flash>hid-flash.exe C:\Users
anda\AppData\Loca\Temp\arduino_build_363784/Serial_Test_Arduino.ino.bin COM44"
All OK!
(As always, don't be shy to connect/reconnect the usb cable to power cycle, and/or press the reset button if something appears to hang)
Hello im arduino uno comanication to stM32f103 ,after cod uplord come erro is compling for stm32 series
What would you need to upload when using the STM32F303 ? Could the same bootloader be used as the Blue Pill?
I'm not sure, someone else was trying the f303 and couldn't get it to work with this or with my f401 video. I would recommend getting an ST link V2, it's well worth it
Could i use that to program it with its Cube IDE ? Thanks for the reply btw
Yep! That's actually what you are supposed to use
In my case, I have to choose a COM port in order for the uploading process to be successful. Do you know why that is?
I think It uploads fine The first time without a com port selected for me, but then I have to have it selected too. I think the reason is Arduino has an old check that makes sure there's a com port selected when uploading because It was designed for the AVR chips that upload over com
Excellent!
Can I use stm32cubeide for programming and upload that loader?
Where I could see instruction?
You can probably set it up but I haven't seen anyone get that working yet. You'd basically need to have a script that runs for upload when the binaries are generated. Again I'm sure it's possible. I would recommend an ST Link V2 if you actually want to use STM32 cube IDE
@@CalebMarting I use ST Link v2 for debugging, I try making custom board. I wanna upload code from flash memory also. Thanks for advice anyway
Is there a way to make an usb Hid device with this bootloader? UsbComposite library is incompatible :(
You can go back to the old core mentioned in my previous video on the topic, although I don't know if you'll be able to use this specific bootloader then
Although I think it is possible to use it as a keyboard and or mouse if you set the USB in the tools menu to hid and use the built-in keyboard or mouse library
I have an error at the connection process with ST-LINK V2 via STM32 Cube Programmer : "OLD ST-LINK firmware, please upgrade it befrore trying to reconnect". And when i click the upgrade firmware button this appears "ST-LINK is not found in DFU mode. Please restart it." Any idea how to fix it?
I think when it says "please restart" just unplug and replug the ST-Link and try again. You may have to be quick but I don't believe it matters, it should lock it in DFU mode
We had an issue like this before on the discord.If you want to join I can help you figure it out there (link in description) otherwise how he fixed it was copying the downloaded hid flash from GitHub into where it expects it in the Arduino15 folder (I forget exactly what subdirectory though)
The "Additional Board Manager URL" link is broken
I've been playing with the Blue Pill and the St-Link Flash utility, and I think I might have erased chip including the built-in embedded boot loader.. is that possible?
The reason, when I switch the BOOT0 jumper to 3.3v and power the board, I see the UART1 TX pin from the Stm32 stay LOW... but I've read that if the ROM bootloader is running correctly, its TX line output should idle HIGH. I tried sending 0x7F (even parity) anyways, but no luck.. no (0x79) response from the chip on UART1 (B7/B6). I also tried UART2/3 (A3/A2, B11/B10).
Is there a way to verify if the embedded bootloader is still there.. or restore it if I've clobbered it? As a test, I was thinking jumping to the bootloader from my application but I can't find the address where to jump. AN2606 says the for medium density devices like the F103C8, that the chip id is 0x410, but only lists the *bootloader id*/address (0x10/0x1FFFF7D6).
The UART bootloader is in rom and cannot be erased. However the chip itself could be fried for some reason. Do you have an ST link or another blue pill? You can make the blue pill into an ST link and potentially still upload code to the one that's messed up. I should have a video coming out about that soon
@@CalebMarting yes, the chip seems to operating otherwise normally.. I can still program it with the st-link (swd interface). Long-shot, but perhaps it is in DFU mode, but somehow thinks the upgrade is coming from USB/CAN/I2C/SPI and therefore its disabled the uart? Seem unlikely as aside from power via the usb-micro, all the other pins are open.. but not sure what else to make of it!
Those pins might have just been fried too cuz I've heard other people have fried only specific pins. Very weird. Perhaps there's some sort of protection feature? Maybe you could use STM32 cube programmer to do a full chip erase, see if that helps
@@CalebMarting Thanks, you gave me a great idea.. test the pins by writing a program that uses UART1... as I was doing that, the Device Configuration Tool shows UART1 to be on P10/P9! Using those pins, the DFU worked! I goofed when I was using a very colorful popular pinout diagram of the blue pill that shows RX1/TX1 on B7/B6..I thought the outer most columns were the default pins, and alternate functions on the inner ones... apparently, that's not the case!
Muito obrigado pelo excelente tutorial.
Hi - thank you for these videos - very helpful! I hope you can find the time to help me - I bought some STM32 boards that seem to be using this chip: STM32F303CCT6 with 256 KB Flash - Robotdyn is the manufacturer. The binaries in the links you posted are for F103 and F407 only - does this mean my board cannot be flashed with a bootloader?
Hello! The f303 supports DFU upload, so you actually do not need a separate bootloader to upload code over USB. you can find this info in section 3.5 of the official datasheet.
www.google.com/url?sa=t&source=web&rct=j&url=www.st.com/resource/en/datasheet/stm32f303cb.pdf&ved=2ahUKEwiv95CQ3LbqAhVGCc0KHQieDuoQFjAAegQIBRAC&usg=AOvVaw316i_atPeBiw5Z2kVGDzC4&cshid=1593973002676
Please take a look at my black pill video, the process is essentially the same for uploading code! ruclips.net/video/b1123kz_3MM/видео.html
@@CalebMarting Thanks for the prompt response! I cannot get my Windows 10 PC to "recognize" the STM32 board, hence why I thought I needed to flash the bootloader. Is this just a USB driver issue then, and if so do you know where I can find the correct driver?
Do you have the boot pins set correctly? You may need to install a driver too, I am not sure
I'm running into a weird issue with PlatformIO! I can upload the code to the BluePill but only once than the laptop says "USB device not recognized", if I re-flash the bootloader then I can upload the code again but right after that get the "USB device not recognized" error.
To get to upload from PlatformIO all I had to do was add "upload_protocol = hid" in the .ini file.
There's a lot of options that aren't checked when you use platform IO because there's no gui. Go to 8:30 in the video and I have a config that works
ruclips.net/video/Myon8H111PQ/видео.html
I have problems !, I get this comment:"Timeout error occured while waiting for acknowledgement.
Timeout error occured while waiting for acknowledgement.
Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again...
"
Do you still have this error? If you do I can walk you through a fix. If you join the discord (link is in the description) it would make it a lot easier to show you how to fix it.
Just click the reset button and retry... you have to listen carefully the explanations in the video before posting !
EDIT: Okay, I found out how to fix that! In my case it was bad, cheap chineese clone of programator PL2303. If you have one of these, you need to find drivers from 2008 (3.3.2.105). They will work on Windows 10. The new ones just block the chineese versions from working. Aside from that, check all the cables if they stick, and don't forget to choose the correct port, in Cube32Programmer in UART configuration, check if other COM ports appear :)
Muito obrigado. Realmente funcionou dessa forma.
Hi, Great Tutorial. How can we do the same thing to Maple mini which does have any jumpers ?
static.leaflabs.com/pub/leaflabs/maple-docs/0.0.12/bootloader.html
This page says you need to tie pin 2 to ground (boot 0) and in the process would be the same. Although I believe the maple mini comes with a bootloader, and you may want to use their official bootloaders as well
@@CalebMarting YES that worked, Thanks
For some reason this works only the first time I upload a sketch after the bootloader was installed. Once the sketch is uploaded in Arduino IDE (PlatformIO as well) I get "Error - [1209:BEBA] device is not found" on all subsequent upload attepmts. The only fix is to upload the bootloader again through STM32CubeProgrammer. What I'm missing?
You need to have the correct USB settings as mentioned in the video, such as Usb support. Also if your Sketch us using HID you can get some interference. If you move the boot1 jumper to the one position and press reset, it will put it in bootloader mode and you should be able to upload again.
@@CalebMarting Thanks for answering - yep, the bootloader starts when boot1 jumper is in position one. However I cannot get it to work (after the first upload) in position zero for both jumpers. My PlatformIO settings are as follows:
[env:bluepill_f103c8]
platform = ststm32
board = bluepill_f103c8
framework = arduino
board_build.variant = Generic_F103Cx
upload_protocol = hid
upload_port= COM14 ;not needed, but the uploader complains without it
build_flags =

Hi Caleb, i am getting the following error
Timeout error occured while waiting for acknowledgement.
i tried all of your troubleshooting suggestions but didnt work, please help
Do you have another blue pill? The quality control on the boards sometimes isn't great
@@CalebMarting @Caleb Marting no, i have a few more on the way, however, i figured out how to use stlink v2 with arduino without the bootloader
Am i the only one who cannot communicate with bluepill over uart? No matter what i tried, it didnt work. I checked A9 and A10 if they are connected to stm chip with multimeter and yes they are. When it is not bootlader mode it just blinks, when it gets bootloading state no respond at all.
Do you have another blue pill you can test with? Sometimes there are defective blue pills, the chips on them especially
It didn't work for me, when I upload the bootloader and reset the board, the led on pc13 blink pretty fast. Then I tried to upload a sketch and didn't work.
I mean it could be a USB cable without data lines, is any device detected when you connect it? The LED blinking means it should be working. You could also try it on another blue pill because sometimes it'll look like it should work but it just won't
@@CalebMarting it was the USB cable. Thanks. It works now.
NOT WORKING!!! My Arduino IDE throws an error saying "Failed uploading: no upload port provided". I used ST-Link V2
After you flash the bootloader you need to hook it back up to the TTL converter and select the COM port and then try uploading in arduino IDE. It then begins to flash something else and it will finally work.
// This method did not work for me, I was able to finish the process and load the "Blink" example, but after loading my own code, the PC did not recognize the blue pill board. I have resorted to your previous video (2018), and the previous method has worked for me wonderfully.
Try again but with 1.8 of core and not 1.9. This worked for me.
//Edit: I was able to update core to 1.90. Maybe the root of my problem was solved by installing a driver for STM32 device. My system recognizes the pill as a generic serial device that helps Arduino when searching for it.
I possibly had the same problem: My Bluepill could send messages via serial over ttyACM0 but it was not possible to flash it a second time. The bootloader was not active anymore (no fast blinking), but the slow blinking occurred according to the example I had programmed. The Solution was to reset the board (or power it up) while the BOOT1-jumper was set to 1. The other jumper! Then the fast blinking reoccurred and I was able to flash it with HID Bootloader method. After resetting I could set the Jumper back to 0. Thus after reprogramming the board the USB-Serial automatically re-activated. Perhaps this should be added to the instructions.
Now I'm very happy with the solution: Small bootloader and defined switching to programming via jumper. No STLink or USBtoSerial adapter needed anymore. Many Thanks Caleb.
@@raulkompass2773 Thanks dude : )
I have tried this and ran into a brick wall when I could not get a CONNECT when clicking on the green button in the STM32CubeProgrammer. I am using a ST-Link32/V2 clone which had been working fine until today. I didn't change anything, but I can no longer program my blue pill with it. I am on W10 and it recognizes the dongle as does STM32CubeProgrammer, which does read the serial number of the dongle. Does anyone have any ideas of how to get this bootloader onto my blue pill? Thanks!
Maybe the clock and data lines were reversed? Otherwise maybe try upgrading the firmware or plugging in the USB and ommiting the 3.3 line
thank you very much...!!!
i cant find my st link dongle and i dont have a serial adaptor, i do have a lot of nanos' megas and wemos bits and even something labeled usb asp.......
I haven't quite figured out how to use another mcu as a serial adapter to program, but if you can find a sketch that lets you do it, please let me know! It certainly seems possible but I don't know the speeds
...I recently got 2 pcs of the infamous bluepill...but both had different chip Id by country..1st one chn other mlys ..both did not work with ftdi..later The mlys worked with stlink ..later on ftdi after pc13 bootloader install..but the chn came with 128kb of uneraseable bootloader detected under hotplug cube programmer.only..normal mode get no target...how to fix it..?
...I got it fixed today....ftdi...check unprotected mode... download bootloader via cubeprogrammer...yeeay
the stm32 cube programmer wont work, ive tried reinstalling java , any ideas how to fix this ?
Is it the latest java version? In the installation directory there were some files that look like you could use them for command line. I bet you could use those to install. otherwise there are specific tools that STM has put out for just the ST link or serial port. (STM flash loader demonstrator for that one) although you will still need to have those command line things installed
it work well...thank you
it gives "Error - [1209:BEBA] device is not found :(> Searching for [COM7] ..." when uploading without a serial adapter
We found two causes for this
1. Defective/knockoff chips
2. Failed upload
To fix the 1st, try a different blue pill board, they're so cheap that you should probably just buy them in pairs or triplets.
To fix the second, perform a full chip erase in stm32 cube prog and then upload again. You can try it one or two times.
More often than not we found it happens with defective chips but it can't hurt to try uploading again after a full erase. We can provide more info in the discord linked in the description
Maybe you just try 1.8 of STM32 core, that helped me. 1.9 may have problems with 2.2.2 of the bootloader, maybe.
