I have my IDE set to the Arduino ADK and I have the appropriate port set.
It's important to understand...I CAN upload successfully - as long as my sketch is below 30k.
So:
- I upload a sketch that is just under 30k - success!
- I add one harmless line of code...say, declare an int, or do a Serial.println...anything that will increase sketch size.
- Try to upload - FAILURE
- comment out any line to reduce sketch size again below 30k size - SUCCESS.
This is purely a size issue - I've tried it on both Windows and MAC machines with two different ADK boards...
All 4 combinations of ADK board and laptop are the same - success with small sketches, failure the moment they go over ~30k.
