Burning bootloader to ATMEGA328P-AU-ND using AdaLoader

[zenwebb]

I assembled a little breakout board for an ATMEGA328P-AU-ND (http://www.digikey.com/product-detail/e ... ND/1832260) thinking that it was the same chip that is used by the Arduino main boards. Apparently, the "AU" part makes it a different chip, and I can't burn the bootloader using an UNO with ArduinoISP.

Whenever I connect my breakout board to the Arduino UNO (using digital pins 10, 11, 12 and 13 and power), then attempt to burn the bootloader using Arduino as ISP, I receive this error (Arduino 1.0.1):

Code: Select all

avrdude: Yikes!  Invalid device signature.
         Double check connections and try again, or use -F to override
         this check.

So, I loaded my UNO with the AdaLoader (https://github.com/adafruit/Standalone- ... programmer), hoping to get the device signature from the board so I can modify my boards.txt file (somehow). Here is the output in the Serial Monitor once I hit "G":

Code: Select all

Reading signature:200
Searching for image...

Image fail

200? Haha, I thought there would be a hex value? Not sure how to proceed.

Did I buy the wrong ATMEGA328 chip? I wanted a 32-TQFN package, but maybe I got the wrong one. If not, does anyone have any idea how to get a bootloader onto it?

I downloaded WinAVR and used it's avrdude to check the device signature. It's 0x000000, which I guess means I fried my chip while soldering. Uh oh.
