I have an ET-BASE AVR (ATMega128) board from Futurelec which I decided to program the fuses as:
SUT1:0 - 11
CKSEL3:0 1111
CKOPT - 1
After doing this, it will no longer communicate. I misread the datasheet, and after looking again, it says that the frequency range for this setup should be 3.0-8.0MHz.
It has a 16MHz onboard crystal oscillator. Any ideas how I might be able to recover this? I've tried parallel programming with an STK500 but not had any luck.
