I have got a 3.5 board and test it with my KEDA motor and everything seems to be fine.
I set the start config to:
and after the beep and the initial run of the motor I started the odrv0.axis0.config.startup_closed_loop_control manually. I was able to give ASCII comands over a virtual Com port.
Sometimes it happens that the motor starts uncontrolled spinning very quickly after the closed_loop_command. I cut the power and start again, I thought that could be a bug of the original firmware. So, doesn’t matter during my tests.
Now I set the odrv0.axis0.config.startup_closed_loop_control to the startup setup and saved it. After powering on, the motor start it`s initializing and shows the error again spinning with full speed. I changed the config command from True to False, saved it and disconnect after that the power supply.
Now my ODrive didn’t responses anymore and the motor initializing will not start. Everything is dead.
What should I do now?
