Bootloader not burning to my Ender 3 Pro

Development Tools Uploading
1

We got an extension kit for our Ender 3 Pro and I need to update the firmware to change the size of the print bed in the system. My bootloader keeps coming back with an error. He is the print out code I get for my error. Kind of out of my realm with this so any help is appreciated.

avrdude: Device signature = 0x1e9705 (probably m1284p)
avrdude: Expected signature for ATmega328P is 1E 95 0F
Double check chip, or use -F to override this check.

avrdude done. Thank you.

I think that might be your problem. avrdude is seeing what it thinks is an ATmega1284P on the Ender's board (which from my superficial 30 second research seems to be correct), not an ATmega328P. So your avrdude command line should probably specify -p atmega1284p, not -p atmega328p.

This is really not my realm so sorry if I get annoying but is there a way for me to correct that? Like a way to change the command even though it happens right after I hit the burn button.

Since I have no idea what procedure you're following (that's a big hint that you really need to provide a link to it if it's online, or otherwise make it available here), I can't give you any kind of useful answer.

If you haven't done so already, install a board package that supports the 1284P. GitHub - MCUdude/MightyCore: Arduino hardware package for ATmega1284, ATmega644, ATmega324, ATmega324PB, ATmega164, ATmega32, ATmega16 and ATmega8535 is one of them and googling github 1284P will reveal a few more.

After installing, select the correct processor (and possibly options) and burn the bootloader.

Note:
No experience with your board or 1284P in general.

Your welcome, don't forget to set up your marlinfw with platform.io in vscode.!
