RE: [AVR-Chat] Programming ATMega128

2006-03-15 by wbounce

I do not have the ponyprog but sometime use a different programmer. I
had in the past corrupted the fuse bits. To get things working again I
had to connect another board to the xtal1 and 2 and generate a 1mhz
pulse on the other board long enough for me to reprogram the fuse bits
to the right clock setting

I had a simillar problem with PonyProg and an ATmega8.
 In my case, I had programmed the fuse bits the
opposite of what I thought I had.  Naturally, I blame
PonyProg for being non-intuitive and confusing me. . .

Good Luck!
