avrdude device signature = 0xffffff

Projects Programming
1

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. I do not think the problem is the Arduino, because I was able to record in another microcontroller.
The microcontroller I use is an ATMEGA328P-AU and to record I use Arduino Duemilanove by ISP.
Could someone help me?

Thanks!

Can you upload the basic BLINK program to the Arduino that gave rise to the error?

If not, post the exact error message that you get when you tried.

Nick Gammon's diagnostic program may help

Sounds to me like one of your ISP wires has come loose.

I tested the cable, wire by wire, and the tracks responsible for power and programming. It's all OK.

avrdude done. Thank you.

0xFFFFFF sig indicates a wiring problem, usually MISO shorted to Vcc.

In that case I suspect that something has gone wrong with the system clock on the target processor. You can't do serial programming unless the processor's system clock is running.

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

The error occurred again. I do not know what to do.

Well, I using a 16Mhz crystal oscillator. I removed it from the circuit and made the programming changes to use the ATMEGA internal oscillator (8MHZ), but the write error continues.

You have to keep the crystal attached until AFTER you set the fuses to use the internal oscillator. If it is set for a crystal and the crystal is not installed... No Clock. Therefore, no serial programming.
