Re: [avr-chat] How to program fuses with avrdude

There are 3 items in the chain that can be at fault: avrdude, your 
programming interface (ICE or whatever you use), and your CPU; can you 
try and assess for the initial 2 whether they work correctly?. Avrdude: 
are you using the right command-line arguments? Interface: what are you 
using - an ICE, the infrastructure of an STK500 or ... ? did you ever 
have a correctly working configuration? ("burned the parallel port": of 
the interface?) CPU: I think it unlikely that you destroyed several CPUs 
in a row - I would say the most likely reason for non-communication is a 
CPU that does not have clock cycles (therefore does not execute 
instructions), but I think people with more experience will have more 
pertinent advice. You should be more specific on the interface you use.
