avrdude :stk500_getsync(): not in sync: resp=0x30
avrdude :stk500_disable(): protocol error,expect=0x14 resp=0x51

plz help

Have you selected the right COM port? My bluetooth device is a COM port under XP and it gets selected before the arduino sometimes.

I have a few Arduino Duemilanove 328’s which I’ve used w/ Ubuntu, Mac OS X and Windows XP all to great success. I’ve recently gained a Windows 7 laptop and wanted to run a few projects from there, but I’m having the same problem as swarooppal1088.

“Problem uploading to board.”
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

I’m on COM3 and FTDI device drivers are installed. I’ll look into it again another day but any links or suggestions would be appreciated.


The most common cause of this error (IMO) used to be people choosing the Duemilanove 128 when they had the newer Duemilanove 328. Click on → and make sure you have the right board chosen, and try again.

Yeah, I had the wrong board selected. Hope this helps.
