So, installed the board.

Steppers: 2pcs tmc2008, with uart activated, according manual. 3pcs of tmc2100 config as a4988 and spreadcycle at vref 0.7v there about.

My computer does not recognise it and connecting it to a headless linux SBC, I can't even type lsusb.

Have not managed to compile either a new marlin nor the one from bigthreetech, so it's what was supplied on the microsd-card.

Any ideas to diagnose further?

Thanks!

I have same problem, i tried to move jumpers for USB Host or USB Flash Drive , changed firmware over 20 times with different code setup no luck. The 5v bridge is works, it seems problems in RX/TX line.
