Topic: Bootloaing AVR chip (Read 1 time) previous topic - next topic


Ah..Just forget about using internal osciallator as it is not that accurate too from what I heard. Just stick to 16MHz and burn arduino UNO bootloader or optibootloader.

Anyway, any difference between optiboot and UNO bootloader ?


I can't answer that, I don't really know.
Perhaps a little smaller with shorter startup delay?

Anyway, thanks for your great help in providing info :)


The Uno bootloader is a slightly older version of optiboot.  There shouldn't be any differences relevant to an ATmega328, unless you're compiling from the source code and making changes to the options.


Can you elaborate more on that ?

Thank you :)
