Re: [avr-gcc-list] ATMega32 fuse bit problem

[Bernard Fouché]

If you focus on erasing the chip to regain control of it, then you can 
use nearly anything that provides logical zeros and ones as a clock.

For instance I  recovered chips sometimes by  using UART traffic because 
I had no other hardware at hand: I took a RS232-UART converter, sent a 
big file from a terminal emulator (with no particular protocol, just raw 
byte sending) and I tried a few times to erase the chip until it worked ;-)
