I've upgraded my board to SKR1.4 Turbo with RepRap firmware. Everything works, but motors move double the request. M112 reports them as 'no-driver-detected'.

But M569 seems to be able to communicate with the drivers:
M569 P0
Drive 0 runs in reverse, active low enable, timing fast, mode stealthChop, ccr 0x00053, toff 3, tblank 0, tpwmthrs 2000 (4.7 mm/sec), pwmScaleSum 0, pwmScaleAuto 0, pwmOfsAuto 0, pwmGradAuto 0, pos 0

M569 P0
Drive 0 runs in reverse, active low enable, timing fast, mode spreadCycle, ccr 0x00053, toff 3, tblank 0, hstart/hend/hdec 5/0/0, pos 0
As you can see, I managed to change the setting from 'stealthChop' to 'spreadCycle'.
I also tried editing the config.g to check if the stepping is set correctly and, unfortunately, it is.
Both M350 X16 Y16 Z16 E16 I1 and M350 X256 Y256 Z256 E256 make the stepper motors run twice the distance in mm required.
I can fix this problem by setting the steps per mm from 80 to 40, but I always ran 80 and online calculators say that my steps/mm are 80.
Is there something that I missed checking? How is it possible that the motors spin twice the required?
