Step 1: The Beginning
Last week I decided to make a classic Arduino clone with an ATMEGA328P-PU. I seemed to be so easy and quick but a very bad surprise for me: I odered the cheaper ATMEGA328-PU (non P!!) that is to say: non pico power.
The difference: this IC needs a bit more energy and IS NOT COMPATIBLE with the Arduino ISP bootloader (see the wrong signature). So I was a bit disappointed.
I looked on the net for a method to boot load this kind of circuit: a lot of methods found but none of them would run with Arduino 1.0.6. So I tested one of mine: a sort of mix between all this tricks. I will give it to you now…
Step 2: The Schematic and the Bootloader to Use:
You can find it easily on:
https://www.arduino.cc/en/Tutorial/ArduinoISP
I use a prototype board to connect all the cables on the photo (components on the top of the board are decorative).
Then you have to follow these steps:
1-download in your arduino the famous example “arduinoISP”, then close Arduino 1.0.6
2-backup the arduino/hardware/tools/etc/avrdude.conf and do the following change (at line 8080 for me in notepad++):

I give you the initial avrdude.conf and the modified file in 2 archives.
3-run ARDUINO 1.0.6
4-select the board Arduino Duemilanove or Diecemilia
5-select the good pprocessor: Atmega328
6-select Arduino s ISP
7-burn the bootload
8-shut off ARDUINO 1.0.6, replace avrdude modified by the original file you back up.
9-now you have to change the file arduino/hardware/arduino/avr/boards.txt to make appear the new board name with this kind of circuit. I called it: Arduino Uno w/ ATmega328 (non-P)
The text you have to insert in it:
##############################################################
uno328.name=Arduino Uno w/ ATmega328 (non-P)
