I have a motor, the phase register is 8 ohm.
I want to drive this motor using odrive34 board, the firmware is newest.
when I set motor_type = MOTOR_TYPE_HIGH_CURRENT, odrive34 report error ERROR_PHASE_RESISTANCE_OUT_OF_RANGE
when I set motor_type = MOTOR_TYPE_GIMBAL, odrive35 report error ERROR_CONTROLLER_FAILED
log info of two case as below:
