Hello, I have made a homemade PCB with the ATMEGA328P-AU (smd) and I want to burn the bootloader using a UNO as ISP. I have done this in the past using DIP microcontrollers with external 16MHz oscillators. This time I want to use the internal clock. I tried this method and selected the "ATmega328 on a breadboard (8 MHz internal clock)" as my board but I got this error:
avrdude: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check.
What board should I select to burn the bootloader on the SMD ATMEGA328P-AU using the internal clock? Thank you
