Settings are lost at reboot


I had that now multiple times.
I set the pre_calibrated=True, save_config(), reboot but this setting is false then. (Yes, the motor was calibrated before setting that).
I set the startup_closed_loop_control=True because startup_encoder_offset_calibration is already true and works, save_config() but after re-connecting the board to power it is not in closed loop mode.
I set the odrv0.axis0.controller.config.control_mode = CTRL_MODE_VELOCITY_CONTROL, all works, save_config(), next time I send a speed command after reboot, it does not work any longer and I have to set it again.

I cannot see a pattern for that. I started to validate that setting the variables did work by reading them immediately after - so it is not that. And I don’t think these are side effects from other things, e.g. neither motor, encoder or anything shows an error, hence should work.

Did you experience similar things?


Lack of an action step to store restart



@wdaehn There is a known issue about the state machine we use for the configuration saving. Specifically, there are issues with saving configuration more than once per boot. Please see if this workaround works for you?


I did definitely multiple saves without reboots. Hence very likely I did hit that. Thanks!
