Re: [AVR-Chat] Problem setting fuse bits of ATMega8535 AVR

2006-09-15 by David VanHorn

The way atmel did the fuses is a bit confusing, and that may be what's going
on.

One thing to check that I didn't see mentioned, is that CKOPT needs to be
changed.  The default state enables a low power "vittoz mode" oscillator
that may or may not run with a given crystal, or worse, will run just barely
enough amplitude to clock most of the chip, most of the time.

I don't have pony prog, so I can't directly help you on the fuse settings.

NOTE TO TOOL MAKERS:  PLEASE PLEASE PLEASE Use nomenclature that is exactly
the same as the chip data sheets!
