[AVR club] Cannot program the ATmega128 using SPI - Francois Rigaud - Jun 4 10:46:40 2007

Hello,
>> Cannot program the ATmega128 using SPI
Maybe you re making a mistake in programming fuse bit.

3 years ago, i have making the same and i restored 4 µc
with this:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Special "Rescue"-Mode: When the Bootloader-Enable jumper is set during
power-up a clock-signal (0,73MHz) is available at the "Rescue-Clock"
pin-header.
With this clock-signal connected to the XTAL1-pin of an AVR a
misconfigured
controller can be accessed and reprogrammed.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Good luck

Cordialement
