Hello community,

I am working on v3.5 and struggling to make the motor turning.
When first boot and I see no error

However when I commanded motor calibration, it won’t turn and I see MOTOR_ERROR_DRV_FAULT.
odrv0.axis0.requested_state = AXIS_STATE_MOTOR_CALIBRATION

Testpoint at FAULT shows high when this happens.
What could cause this problem? any idea?

These UNKNOWN ERROR’s usually suggest outdated firmware or odrivetool, in general you should update them both.
However, in this case you seem to be using v3.5, which is no longer supported. I would suggest upgrading to an ODrive S1/Pro, or a v3.6 if the older design is a necessity.

Out of curiosity, did you recently purchase this v3.5?
