New Pi 3, New install of Jessi, fully updated, new install of Arduino IDE, new install of Arduberry github files.
Any attempt to program Arduberry with anything connected get following error:
avrdude: AVR device not responding
avrdude: initialization failed. rc=-1
Double check connections and try again, or use -F to override this check
I have to disconnect anything I have connected to the arduberry (even a simple LED will cause this error and the upload to fail).
