Burning Arduino Bootloader

Question

I'm trying to use an atmega chip from an arduino on a breadboard, with minimal hardware (using the internal 8mhz clock). I am using the article in the link provided. When I reach the final step (burning the bootloader), I get an error telling me the device signature is wrong-

Arduino: 1.8.5 (Windows 10), Board: "ATmega328 on a breadboard (8 MHz internal clock)"

avrdude: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check.

Error while burning bootloader.

I am assuming the error is because the chip is from a uno clone, and uses an atmega328p-pu chip. How am I able to override this check using -F, as described in the error message? Or is there maybe some other way i can fix this? Thanks in advance.

Answer 1

One of the parameters that you have to give avrdude is the microcontroller you are using, and then it checks the signature of the micro to ensuere that everthing is ok. this parameter is passed through -p flag

avrdude -p <microcontroller name>

For ATmega328 this parameter should be m328 and in your case, with ATmega328p this parameter should be m328p. All options avalible can be checked in man page.
