I was developing a firmware for a device, constantly recording and verifying the results and correcting the errors, until a certain moment appeared the error message when trying to record: "avrdude device signature = 0xffffff avrdude yikes invalid device signature", no longer performing recordings. …

avrdude device signature = 0xffffff

The ATMEGA328P-AU really burned. I traded for a new one and it all worked out perfectly.
