I made a custom PCB with an ATMEGA328 on it. However, when I try uploading the bootloader, it gives me this error, below. I think it's because this is a new ATMEGA328, and that if I override the check it should be fine. How would I do that, and what does "use -F to override" mean?
Thanks so much,
Arduino: 1.8.13 (Windows 10), TD: 1.53, Board: "Arduino Uno" avrdude: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check. Error while burning bootloader.
