I'm nearly finished with my Nybble, but have run into problems uploading software to the board. Whenever I try, I see the following error:

avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x65
An error occurred while uploading the sketch

When I check the serial monitor, Writeinstinct.ino is running, but I'm not able to send commands. It was working yesterday, but something in the chain is off. I'm using Mac OS and Nyboard 0_2. I've tried restarting, different USB ports, etc. Any advice is welcome!
