I haven't fiddled with the arduino toolchain, but instead blown away the bootloader and just used the unit as a bare AVR development board with avr-gcc, so haven't had that issue. However, it looks like arduino users have found various ways to produce that type of error message: http://www.instructables.com/id/A-solution-to-avrdude-stk500getsync-not-in-syn/ http://forum.arduino.cc/index.php?topic=28223.0 There are doubtless other google hits which describe causes and fixes, and there are youtube clips on the subject - though they seem a tedious way to fight your way to anything informative. Your device seems to match, leaving correcting mismatched com ports, pressing reset, and disconnecting RX, as potential fixes. Good luck.
