my toneboard was working fine with a vim3 for some time, although it hat the oddity that it would only work if connected to USB and GPIO, GPIO alone would not work.
As I started it in he morning, I cannot connect to the board.
I checked with my gentoo pc:

Sorry, I dont have a camera at hand, but it is a straigt connection from the toneboard with usbc to usba on my pc motherboard. I have already tested several cables (khadas genuine among them) and also my notebook and vim3 -> same effect
