Duemilanove Bootloader on Uno Board

Development Tools IDE 1.x

Are there any foreseeable problems with using an Atmega328P-PU with a Duemilanove bootloader on an UNO board?

I was trying to connect to this old Uno I had put away. I could not communicate with my PC and Uno... I finally just tried setting it up as a Duemilanove and it worked. I suspect the uC has the wrong bootloader.

Thanks

It may be an older version before the uno optiboot.

Yes, you can live with it at a duemilanova, but If you have another uno or duemilanova it is very easy to burn the updated uno bootloader.

You will get more program memory size, and it is supposedly faster than the duemilanove bootloader. You wont have to remember to select a different board if you re burn it as an Uno.

The "board" menu in the IDE can be misleading sometimes. Really, it is referring to what bootloader will avrdude be talking to. So if you put a Duemilanove bootloaded chip on an Uno board, you just turned the Uno into a "Duemilanove" board. (And vice versa.)
