Let’s back up a second.

  1. is there any visible activity from the LED’s upon power up or when the reset button is pressed?

  2. have you attempted to upload a sketch via FDTI/serial device? If so, what board type/attributes did you use?

  3. what did you do (command line, ide selection, etc) that generated error message in #9?
