Arduino Due not in sync

Official Hardware Mega Due
1

Hi All,

I purchased an arduino Due, hooked it up, and got the following synch error: avrdude: stk500_getsync(): not in sync: resp=0x00

I tried reinstalling the driver, IDE (1.5.6-r2), double checking the COM port, and nothing would let me upload the sketch. I also tried all of the different variations of resetting just bofre or just as I was uploading the sketch. After a positive loopback test, I concluded that the 328P chip was bad, so I returned it. Got a new one, and I have the same problem. I can;t imagine the odds of both 328P chips being defective, and I can;t help but suspect user error, on my part.

Any other ideas of things I can try to get this thing working?

Thanks so much.

Hello gidmark,
I am sorry your first encounter with DUE was not the best (as it should be).

Every time I see the word AVR instead of ARM in the Arduino Due's world it means to me that in some way I am trying to mix (or mess) both architectures. It can be a software issue (like trying to access AVR libraries) or a hardware issue (like trying to config an AVR board (UNO, LEO, MEGA, etc). See if you are using the correct board: Tools->Board->Arduino Due (programming or native). May be you are trying to run a sketch that use a similar AVR library. If that is the case, clean for a moment your: ...\Documents\Arduino\libraries. Regards!

I think you forgot to select the arduino due board. The due doesn't use avr dude, but bossac.
