I have the VOXL FPV ESC and I cannot spin/ calibrate one of the motors. 3 motors spin calibrate fine but one motor spins very intermittently. I tried replacing that motor but same behavior.

Screenshot of the ESC detection:

Good motor spin:

Bad motor spin:

I think it is a bad ESC, but need your guidance if this can be fixed. The output when running this motor is different: it shows extra BOARD_VOLTAGE, and BOARD_CURRENT fields when spinning. Also it knows the RPM keeps going to zero.
