VESC can't control motor anymore

ESK8 Electronics

After only about 15km on this VESC (egreenmotion) it stopped working and when I pull the trigger on the remote a red LED flashes 3 times, stops and flashes another 3 times. BLDC tool can connect fine but also cannot controll the motor. Detection fails, LED response is the same.

are you getting any faults?

type “faults” in terminal and post results. If it’s a DRV failure, you’re gonna need a new one.

for some reason when I connected to the vesc after it stopped worrking “Sensorless - Communication Mode” under Motor Configuration > BLDC was set to “delay” instead of “intergrated”. I don’t recall doing that.

and here is a video of the issue

You have buggy firmware, as shown by the 50.00 max current ramp step. In addition to replacing the DRV8302 chip you need to update your f/w to get rid of the bug.
