Troubleshooting

  1. Try a different USB cable (some are power-only, no data)

  2. Check for loose connections

  3. Double check that you have the correct board selected

  4. Double check that the COM Port you have selected goes away when you unplug your board

  5. If you still have problems, make a post here that explains what is happening. and I will try my best to help. Please include as much info as you can including: 

    1. what board you are trying to upload to​

    2. if the com port goes away when you unplug

    3. how far along in the process you are able to get.

    4. any error message when you upload

    5. the color of the lights on your board and if they are flashing
