ok so this has happened to 2 chips so far so might just be my bad luck :P
anyways i tried to burn a mega328p using a dueimlanove as the ISP and using the arduino 21 app on Mac... it immediately complained that the programmer was responding. i reseated the connections and tried again, then it started saying signature error..
i installed crosspack for mac so id have command line access to avrdude to run it manually and it came up with avrdude: Device signature = 0x1e9514 avrdude: Expected signature for ATMEGA328P is 1E 95 0F
using the force option i wrote the boot loader to the chip (it failed once, tried again it verified correctly)
i popped the newly flashed chip into my dueimlanove's board to write a test sketch and now it gives a programmer not responding error...
This happened to me before with 2 mega8 chips and i only managed to get one flashed with the boot loader
I started all this following the instructions here but it doesn't work for me -_-
ps- my dueimlanove has a m328p chip as well in full working order
