ok, so I bought a new Arduino Mega 2560 and I can't get the thing to program. I'm using IDE 0021 on win7 64. Aside from a timer issue on the board, I didn't have any problems getting my older Mega to program.
When I plugged the 2560 into my USB port the LED on port 13 started blinking continuously without stopping before I even loaded a sketch onto it. When I try to load the sketch I get the following error:
Quote: Binary sketch size: 1960 bytes (of a 258048 byte maximum) avrdude: stk500v2_command(): unknown status 0xc8 avrdude: initialization failed, rc=-1 Double check connections and try again, or use -F to override this check.
avrdude: stk500v2_command(): unknown status 0x01 avrdude: stk500v2_disable(): failed to leave programming mode
What does it mean when the LED flashes continuously?
I've tried changing the com ports, but com3 is the only one that shows up. I've double checked and board is set to the Mega 2560
Any ideas or should I return this thing while I still can? Thanks
