You are burning the wrong .hex file.
To be an UNO, use the hex file in the bootloaders/optiboot directory.

Thanks, this was exactly the problem smiley. Everything works fine now.
2  Using Arduino / Microcontrollers / [SOLVED] Burning Arduino UNO Bootloader with AVR Dragon and AtmelStudio on: October 04, 2012, 05:57:08 am

This problem is solved and this post now describes how to burn the Arduino Bootloader onto an ATMega328P with AtmelStudio using an AVR Dragon (or any other ISP).


I want to burn the Arduino UNO Bootloader with an AVR Dragon to an ATMeage328P-PU, but after everything is done I can only use the chip as a Duemilanove Board but not as an UNO.

Here is what I did:
I soldered a ZIF socket to the AVR Dragon and connected it like this:

From the AtmelStuido Help

Also I added a 16MHz Crystal into the same slots of the ZIF socket of PIN 9 and 10 of the IC (otherwise I cannot even read the device signature; If the chip was set to the internal clock this would not be needed).

After this I started AtmelStudio 6 and went to Tools->Device Programming.
There I set the ISP Clock to something low like one MHz (or even less).

Then I went to Fuses (this is probably where things went wrong) I selected the following:

BOOTSZBoot Flash size=256 words start address=$3F00
SUT_CKSELExt. Crystal Osc. 8.0- MHz; ... 16K CK/14 CK + 65 ms

And in the lower tab:


And as the last step I went to memories and selected the bootloader .hex file (arduino-1.0.1\hardware\arduino\bootloaders\atmega\ATmegaBOOT_168_atmega328.hex arduino-1.0.1\hardware\arduino\bootloaders\optiboot\optiboot_atmega328.hex).

OK, everything went fine, but if I go to the Arduino IDE I have to select Tools->Boards->Arduino Duemilanove w/ ATmega 328.

However I want to use it as an Arduino UNO.

Can anyone help me please?

Kind regards,

//edit2: "westfw" provided the solution, so I edited the post so that it can be used as a tutorial.
