So this is not a good sign if it stays lit because something else is communicating on your board. I suggest that you attach the controller by just the 4 wire without additional hats.
Ensure /dev/serial0 points to /dev/ttyAMA0
Try applying power to the controller at the exact moment you run avrdude. If you cannot get it working, please contact me by email and as a last resort I will send you a new controller.

Is there a chance you can try the tinypilot image to verify the motor controller?
