TMC2100 stepper motor drivers not detected on SKR 1.4 turbo with RepRap firmware I've upgraded my board to SKR1.4 turbo with RepRap firmware. Heated bed and heated nozzle work, but motors do not move.
OctoPrint reports them as 'no-driver-detected'.

I tried to figure out what is wrong, but did not find good documentation for this combination of hardware.
This is how I setup the drivers.

I removed all four jumpers from the board below each driver (MS0, MS1, MS2, RST).
Plugged each driver to the board making sure that the corresponding pins match (GND to GND etc.)
Checked voltage between ground pin of the board and VREF pin of the driver. The voltage was 1.365 V (same for each driver). This is a bit higher than some guides suggest, but the drivers worked perfectly with the old board.

Some guides suggest modifying driver timings if the motors do not move, but I was unable to find the right timings for my drivers. What could be wrong in my setup?
As @towe mentioned, 'no-driver-detected' messages in Octoprint log are harmless if you have TMC2100 motors. After experimenting with RepRap settings I found the correct configuration that works with my hardware. Here is the relevant part of the configuration.
