Hello everybody,
I am trying to bootload Atmega2560V, I am having a hard chance trying to bootload these chips :(, THese chips are set to incorrect fuses - I am running threads at AVRFreaks and GitHub.
I am pushing 1Mhz to XTAL1 of Atmega2560V and tried burning bootloaders, I am getting an unexpected error
avrdude: Device signature = 0x1e9803
avrdude: Expected signature for ATmega2560 is 1E 98 01
Strange right.? I know there's no "0x1e9803" such device signature exists.
The full verbose output is here :
Arduino: 1.8.3 (Windows 10), Board: "ATmega2560, Arduino MEGA pinout, 2.7v, Disabled (default), 1 MHz internal"

Double check chip, or use -F to override this check.avrdude done. Thank you.
Error while burning bootloader.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
What could be the issue.? Why it's showing different Device Signature, This is 100% Atmega2560V and it supports MegaCore bootloaders as well, I want to solve this as quickly as possible because I have low deadlines.
Can I change Device Signature in avrdude.exe and avrdude.config from 0x1e9801 to 0x1e9803 .? so that it works in my case.?
or any other way around.?
Thank you
