Electronic – Arduino’s “Upload Using Programmer” for ATmega328 (not ATmega328P)

arduinoavravrdudebootloaderprogrammer

I am using the the Atmega328 (not the Atmega328P that is standard with Arduino) on a breadboard version of the Arduino. I am able to get the bootloader on the Atmega328 using these instructions. In summary, you add a new entry for the 328 to the avrdude.conf file and the boards.txt file.

Then, I am able to get my program on the chip by going to Tools>Board and setting it to Arduino Uno w/ ATmega328 (non-P) then burning the bootloader on the chip using the 328 config files with the AVR Pocket Programmer. Then I go to Tools>Board and switch it to Arduino Uno and upload the program using the normal USB connection.

Now, my question is about using the File>Upload Using Programmer functionality. When I do this for the the Atmega328p on a fresh chip everything works. However, when I try it for the Atmega328, with the IDE set to upload to Arduino Uno it throws the error:

avrdude: Expected signature for ATMEGA328P is 1E 95 0F
Double check chip, or use -F to override this check.`

Is there another config file that has to be changed to enable the "Upload Using Programmer" functionality on other chips? If anyone has some tips on where to look it would be greatly appreciated!

Edit1:

I also tried setting the IDE to Arduino Uno w/ ATmega328 (non-P) and it throws this error:

Edit2: Here is another person with the same problem but without an answer.

Best Answer

You could possibly solve the problem by trying the following variant of your approach:

Edit avrdude.conf (located in \hardware\tools\avr\etc) by going to the Atmega328P entry and then replacing "0x1e 0x95 0x0F" with "0x1e 0x95 0x14".

In other words, REPLACE Atmega328P's expected signature with that of Atmega328 (i.e., NOT make a separate entry, but instead actually replace... so as to essentially attempt to trick the IDE).

Be sure to restart the Arduino IDE after saving the .conf file.

Now, continue with "Upload using programmer", with Atmega328P board (i.e., the original) selected.

If that fails, you may instead use an FTDI board/cable to upload, if circumstances allow.
