Hi !
I have the same problem.
I'm using :
- Arduino diecimila
- Windows XP
I suddenly got the "avrdude : stk500_getsync():not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51"while programming with an accelerometer, and some sound variations on PWM.
Now I can't upload anything to my board, even after turning everything off, and disconnecting. The led on pin 13 blinks when reset, and blinks all the time if I try to upload something. I also checked the serial port on the computer, which name is under 10 (COM4), and works correctly. I tried on several computers, and it still the same.
Could you help me ?
Thank you !
