Dear all
as a arduino user for a few year i haven't encounter much unsovable problems until now.
I am using a uno as a arduinoisp to burn the bootloader on a pcb with a ATMEGA2560 on it.
Afther a while , afther a lot of activity on the rx-tx leds , i recieve a error message:
AVRDUDE : verification error , first mismatch at byte 0x1e000
                0xff !=0x0d
AVRDUDE : verification error , content mismatch.
I am using 0022  and tryed it with 1.01   
Has anybody any experiance with this error ?
Thanks .
