Avrdude verification error while using Arduino as ISP to program another Arduino

Hi guys!

I have two boards: an Elegoo Mega 2560R3 and an Arduino Duemilanove.

I'm trying to use the Mega programmed as ISP to write a sketch on Duemilanove to avoid the bootloader.

I've followed a lot of guides and double checked the pinout. On Avrdude:

avrdude: verification error, first mismatch at byte 0x012f
         0x00 != 0x92
avrdude: verification error; content mismatch
avrdude: verification error; content mismatch

Can anyone please help me to solve this?


I think that there is some problem with the actual NAND EEPROM(storage chip) of your board.

Could be wrong not an expert...

Thanks for the reply!

Are you talking about the nand of the duemilanove?

The issue shows only when I try to program it via ISP. If I upload a sketch using the normal procedure, no error shows.
