configurator create lines:
stepper.TmcUartPins = {E.0, D.3, D.0, C.6, D.12, E.11, B.9, B.0}
I think there is error, PB9, is on I2C connector not on EXP1.
In my opinion there should be:
stepper.TmcUartPins = {E.0, D.3, D.0, C.6, D.12, E.11, E.9, B.0}
I don't have SKR2, board and I can't check this with this board. I just make some research to run BTT Octopus Pro with BTT-EXP MOT, maybe two BTT-EXP MOT :).
