This programmer worked fine and successfully flashed an ATmega168 with avrdude on the first attempt with the blink_1MHz.hex file, and also another 10 times there after with slightly modified blinking hex files. I may have accidentally powered the breadboard from a wallwart with the 5Vcc from the programmer plugged in as well but I don’t think this should have been a problem.
The programmer is still recognized by windows Vista and says its working correctly however when I begin to flash the initialization fails, rc=-1 and when run with the -F flag it says device signature is 0x000000 and the expected Signature for the ATMEGA168 is 1E 94 06. I should also note that the D- status LED is constantly on when the board is sitting idle with the Power and Stat 1 LEDs on as well. Is this normal?
I’m beginning to think the programmer may be broken as I have a second never used ATmega168 that the programmer can’t read a signature from either. The first one still blinks an LED too! Or can the chip still be bricked? Any help would be appreciated.
