When I attempt to image the 32U4 I get the following...

The cable is not the issue, I can access the board with the arduino API with no problems using the same cable.

Any ideas?

If you have a different data-capable USB cable, could you try that? Also, you have the USB cable connected from the Raspberry Pi to the 32U4 right?

I have tried 3 cables, all work for other data transfer situations. I have tried all 4 USB ports on the Pi with no luck.

Couple of troubleshooting steps:

If this doesn't work, SSH into the pi (ssh pi@10.0.0.2) and do ls -l /dev/tty* to see if /dev/ttyACM0 is listed there.

Couple of worst case options:

Initially this did not work. I noticed that the Roma power switch was off. It was lit up and led 13 was flashing. I powered everything off, turned on the pi. The Romi has lights when the Pi is powered on. I SSH'd to the pi. The ttyACM0 dev was flipping from being there to not and the 'Update Firmware' button was also flipping. I turned the Romi power switch on. The tty dev stabilized. I was able to update.

Thanks for your help. I think the issue was the Romi power switch.

  • Unplug all USB cables from the Pi, and restart the Pi.
  • Once it starts up again, verify that the Update Firmware button is NOT enabled
  • Plug in the 32U4 to the Pi, and verify that the Update Firmware button is now enabled

If this doesn't work, SSH into the pi (ssh pi@10.0.0.2) and do ls -l /dev/tty* to see if /dev/ttyACM0 is listed there.
