Dan,
Try the obvious things first:
Make sure the correct device is selected (ATMEGA8515, not AT90S8515)
Make sure there are no other devices still plugged into your STK500 (I do this
regularly)
Make sure there are no extra jumpers installed on the IO pins
Double check the clock configuration pins if you've selected an external
oscillator before.
If the program got that far into (attempting to) programming the device, then
the serial port settings are correct.
Try erasing the part a few times.
Let us know if you get it to work.
Thanks,
Dale Wheat
