Hi, I tried to upgrade my breadboard arduino, and ended up ordering some Atmega328-PU instead of Atmega328P-PU chips. I could burn the bootloader to them by modifying the avrdude.conf file with no problem, but the problem I'm facing is, the chips aren't working with any bootloader other than the Uno…
