I don't understand why you're losing the source-level information by
splitting the program.

After all, you aren't going to jump into arbitrary bootloader
locations from your application, are you?  That would be poor style
anyway.  Instead, put a jump table somewhere into the bootloader, and
use that one.  That way, if your bootloader changes, your
application(s) can still remain intact.  Then you can debug the
bootloader, and if it works, the application.

AVRDUDE is a programmer, yes.

AVaRICE + GDB
