Hello,
I recently bought a arduino mega 2560 and im trying to upload marlin firmware on it (this one) but I have a little problem, I keep getting the out of synch error.
running windows 7 64-bit, tried numerous drivers, tried arduino 0023, 1.0.1, 1.6.4 and 1.6.7. on every version I added the sanguino addon. tried diffrent cables and tried pressing and/or holding the reset button on diffrent times.
I also tried this with 2 diffrent mega boards. I know there are a lot of threads on this but I can't find a solution.
Also I added the error message, hope I could give some more info
Arduino: 1.6.4 (Windows 7), Board: "Sanguino, ATmega1284 or ATmega1284P (16 MHz)"
