The PC and Arduino install work fine on other boards so it is not the port or cable etc.
The upload tries 10 times and then fails with:
Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xb2

Any suggestions?
