Troubleshooting and Debugging

Inspecting USB

To check whether your operating system identifies OpenSK over USB:

On Linux, try lsusb or dmesg.

On macOS, use the ioreg tool:

ioreg -p IOUSB

Debug console

You may need to install extra udev rules for probe-rs.

To flash a firmware that prints more debugging information, remove --release from the flash command, and add --log=trace/debug/info/warn/error with the level of your choice.

Adding debugging to your firmware increases resource usage, including

• USB communication speed
• RAM usage
• binary size

Depending on your choice of board, this may affect functionality, e.g., cause packet loss.
