hi,

Dennis Welbourn said:
If you want to replace the original bootloader, assuming it's located in flash, why not create an application to (re)write the bootloader? Use the original bootloader to load the bootloader bootloader, then run that to rewrite the bootloader.


No, Atmel does not allow it. Their bootloader placed in FM1 part of flash memory supports only parallel programming by programmers.

Oleg
