I'm interested in using openOCD to read from a Risc-V on an FPGA (Microchip's PolarFire). I configured SoftConsole(Eclipse) to download the elf using a Flash Pro JTAG dongle. However, not sure I understand what's happening under the hood. I understand OpenOCD is a local server that accepts commands from the IDE.. yet, how does it talk to the Flash Pro Adapter? I see another local server (fpserver") is running, which I assume listens for commands from OpenOCD, yet how does OpenOCD know how to use this server? I don't see any (API) documentation for fpserver!

The board is out of stock. Where to buy it?

Any thoughts how you can dump the chip's memory to a file? I purchased a FlashPro4 jtag adapter to program a Cortex-M3, but not sure how all this works. From, what I see, OpenOCD is a GDB server running on your computer, but uses "fpserver" to talk to the FlashPro4 jtag adapter/chip? So while Eclipse can download the elf using OpenOCD , I can't telnet directly to that port using putty (4444) . Interestingly, I *CAN* telnet to fpserver on 3334, however that seems to be an undocumented API.. so kinda in limbo.

Should have covered your password :-)

Correction in Video: At approximately 5 minutes and 50 seconds, I say that the SoC is J721s2, also known as AM67. I'm afraid that's not right. It should have been: J722s is also known as AM67.

Joel Fernades and you have been great at covering kernel debugging. Another great video. The only grouse I have with BeagleV-Fire, BeagleY, etc is the use of Tagconnect pins for JTAG. How hard is it to populate a 10 pin micro-jtag connector ffs?

How can i create this kind of flight plan ? Any suggestion ?

Excellent presentation! Does the BeaglePlay have the XDS110 built-in by default? If it does, it means I don't require a J-Link/Lauterbach right? Also, do I need a TUMPA with the BeaglePlay since there is provision for a Tag-Connect? All I need is the Tag-Connect and TC2050-ARM2010 Adapter, right?

Neat trick! Pretty cool that usbip supports wsl now!

Would be awesome to see that self hosted stuff

Factual correction: LA-3780 is available for ~71 USD.

VSCode was meant to be an editor not an IDE? WHAT!!!

Nice!🔥

Nice explanation, please can you make some introduction to the BeaglePlay board , i'am planing to get this board , thank you .

Very Informative 💯

Never seen an aspect ration this wide. Wow! That 103 does stall very easily, unfortunately. Wish the author had used the more powerful engine's model. Thanks for sharing.

what is this from?

it was nice tutorial ! thank so much ! But when i 'm following these steps. I got echo (" Output :") on screen, and i typed ( loadb -f /dev/ram0 ) but nothing happen. Help ???????

@aynusbay depends on the images you choose to put on it - the choice of u-boot and MLO is important - if you decide to use the version for diagnostics, yeah it will be similar to first use.

@hydrohobbyist - yes, the pserial is an alternate to pusb - it could be used instead - i personally have not created a video around it yet :(

Is there anyway of sending the x-loader from a windows terminal? i dont have linux at my disposal nor the experience to manipulate files on a live cd. I have tried using kermit protocol but it says failed.

@all thanks..

it works! thanks! great work.

Hey nice video.. i was planning to get a beagle board and ubuntu on it... im not much of an embedded system guy so i dont really know how these things work..all i know so far is it runs ubuntu..but it doesn't come with wifi inbuilt so i was wondering if an external usbwifi card would be supported? are the device drivers processor specific as in will the normal drivers work on an arm procsor? i am trying to build a device which can do packet injection.will it run when attched to the beagle board?

Gee thanks.. I have wished i had a little more time to clean up the video though.. anyways, there are couple of things planned: a) get the usb2tty working. - probably on u-boot v2? b) redo the video with that.. might be faster need to consider dumping u-boot v2 though.. if only we could make u-boot v1 work as good..

This is a good video...I've read the comments by jadonk...good critiquing! Thanks for posting and I wish you well on the advancement of your BB project!

Autoprogramming: It already does, I just explain what it does in the video..

usbtty: Not with the mainline version of uboot from denx tree. If we manage to push usb2serial adapter to u-boot mainline, yes we can do it.

fonts: I am still learning ;).. hopefully I can fix it up.. hmm.. must be my excitement with trying various styles causing this..

jadonk, Thanks for the feedback..
