Topic: Making an UNO boot load chip work on Duemilanove? (Read 1 time) previous topic - next topic

I make a project with my students where they have to remove the Atmega 328 chip from the Arduino Duemilanova and use it in a stand alone project. I have always bought chips that are boot loaded for the Duemilanova. I am no longer able to find those chips so I bought 30 boot loaded for the UNO. I have found out that those do not work with the Duemilanova. Is there a method or printed procedure any one knows of for re-imaging the UNO boot loaded chip to a Duemilanova chip?

There is no reason a Uno bootloader 328p chip will not work in a Duemilanova board, you just have to remember to select the Uno board type on the IDE before uploading. I have burned the Uno bootloader on several of my 328p chips and they run on any of my 328p based boards, or standalone circuits with out any changes required other then to remember to select the Uno board before uploading.

Well that worked. Never crossed my mind that it would be that simple.

In the future, you might want to just buy bare ATmega328 chips and burn the Duemilanova boot loader onto them.  Might save a few $ that way.

And if you want to save more money, the ATMega328 will work just fine as a replacement for the 328P. I use them here with no issues.
