I am facing some problems with the controller board.
At the very beginning, the controller board didn’t work until I plug in the USB cable of the top interface board. Now the arduino is running and Beaglebone black without it the led power and RX are on (Led4 is flashing). I dunno what happened but it is supposed nothing get work without plug in the USB cable! Any thoughts?
And now the leds aren’t working anymore I don’t know why how many time I keep trying “pressing i, o and p” nothing work when apply a direct power for the leds it works very fine but I don’t know why isn’t working with arduino.
