SOP: Testing and Troubleshooting Device Connectivity
Objective : JTAGENUM: Arduino Nano Troubleshooting [ Hardware Hacking]
To test and troubleshoot device connectivity using serial commands and terminal commands.
Key Steps
1. After flashing the device, unplug and plug it back in.
2. Open the serial command interface.
3. Select the device and establish a connection.
4. Send a test signal (e.g., edge command) to check connectivity.
5. If the signal is not received, close the interface and terminal.
6. Reopen the terminal and run the troubleshooting command: `screen /dev/tty.usbserial-115200`.
7. Verify the program is working successfully.
8. Connect the Arduino Nano to the board and locate the JTAG pins.
Cautionary Notes
Ensure the device is properly plugged in before testing connectivity.
Follow the correct syntax for terminal commands to avoid errors.
If the signal is not received, check connections and settings before troubleshooting.
Tips for Efficiency
Use descriptive names for devices to easily identify and select them in the serial interface.
Keep track of troubleshooting steps taken for future reference.
Regularly check for firmware extraction tutorials and updates for efficient troubleshooting processes.
