Hello, Im trying to port a flavour of devuan to the arduino uno q, the port itself is built successfully, but booting doesn't initialize the cpu ( as i see from the debug leds ) , is there any way of debugging the boot process. This is the image if anyone would help to test

See this section of the **UNO Q** user manual:

Will this aliexpress adapter work well?

Yes, that should work fine. Just be careful to place the voltage level jumper on the adapter so that it uses the 1.8 V level that is safe for the UNO Q's microprocessor.

serial port worked well for me. Ensure it is 1v8 though.
