I'm trying to load the Arduino bootloader onto some ATMEGA328-PU-ND chips I got from DigiKey (http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=ATMEGA328-PU-ND), but am having an error thrown at me from the IDE.
I have loaded the ArduinoISP sketch onto a Duemilanovae clone (Freeduino from NKC Electronics), and have wired up an ATMEGA328-PU-ND on breadboard as described by the Arduino website: http://arduino.cc/en/Tutorial/ArduinoToBreadboard
I have wired up an external 16 mHz clock w/ 20pF capacitors for the ATMEGA chip.
The error I am getting is from avrdude, saying "Expected signature for ATMEGA328 is 1E 95 0F". Doing some checking in these forums, I found a couple similar topics, but for slightly different ATMEGA chip models (mostly P-PU variety).
How can I go about fixing this error, and does this particular chip variety need any special considerations compared to the P-PU?
