I've been using the Arduino on my Bolt and recently had it drop off of USB and not come back after a reboot. I followed the udoo instructions to disable the modem manager and shorted the reset pin, and the Arduino came back but then dropped off again as soon as I ran my sketch again (~3 seconds into running). I have it connected to a bunch of buttons and lights, plus a WS2812b LED strip with a separate 5V power supply (grounds tied). I ran a sketch animating the LED stirp overnight without any problems and haven't touched the hardware since. But my most recent edits send a lot more data over the serial port, so maybe that's killing it? I'll try to hardwire a reset button so I can experiment with this, but I'm curious if anyone has ideas of what could be kicking it off.
