first attemp at uploading to arduino uno

i just received an arduino mega 2560 and am using a generic pc running win xp.

i tried following all the directions to ‘get started’…correct board, correct com port…

i wanted to load the first basic example program to blick an on board LED at one sec. intervals but when i attempt to upload i get this message at the bottom of the screen:

avrdude stk500_getsync() : not in sync: resp=0x00

avrdude stk500-disable(): protocol error, expect=0x14, resp=0x86

not sure what this message is telling me and what i’m doing or not doing that

causes a failure to upload

avrdude stk500_getsync() : not in sync: resp=0x00

The "not in sync" error tends to mean that the PC is not communicating with the Arduino at all.

billgull,

I suggest you check the Arduino type setting in the iDE. “Uno” and “mega 2560” are not the same thing.

Also, there has been a change in interface chips in the Mega boards, so you may need to update your Arduino IDE and pick the correct setting for whichever interface chip you have.

Good Luck,

Eric

I had this problem on my Windows computer. I fixed it by installing the Arduino drivers.

Control Panel → Device Manager

Right click on “unrecognized device”

Install drivers from a location on my own computer

Go to the Arduino folder, select the “drivers” subfolder

Install.

Worked great after that!
