Hi,i'm so stupid i bought atmega328 chips instead of atmega328p, so now i cant use the embeded bootloader burner. I surfed the web and of course there are some ''how to'' and video to show how people did burn a 328 chip, but for me nothing works.


Can someone help me to make those little chips work with arduino?


My IDE version : 1.8.10
Myboard that i want to use as a programmer : UNO R3 with the OEM ATMEGA328P U
Target chip to burn : ATMEGA328 U


Wiring is okay cristal, cap jumpers.

Communication to the UNO is also ok, i can upload anyskect i want. (i tried blink and it works) so i decided to upload successfully the arduinoISP sketch

I tried to replace the boards.txt and avrdude.conf files but it was worst, impossible to upload a sketch. bunch of errors.

I trieds different programmer, board selection etc, i always got a message that said it's a 328p and it can be burned.




So what should I do now? Some surely has successfully done this before, I can't believ.

Do this:

  • Install MiniCore, following the instructions here: https://github.com/MCUdude/MiniCore
  • Tools > Board > ATmega328
  • Tools > Variant > 328 / 328A
  • Tools > Programmer > Arduino as ISP
  • Tools > Burn Bootloader
