Hi Joerg,
the problem is following:
In my working application I get data from an interface (e.g. UART) and I
will write it into the Flash. This is necessary for changing the
application during a software update.
I will divide the application flash section into 3 parts where I have 3
different applications. The boot loading process shall decide which part
shall be used.
I use the ATmega128.
Regards,
Thomas

In the question there was an error but you understand it
correctly. I would ask for the functions in <avr/boot.h>. I am not
sure that these functions also useable for application flash
section.
Depends on what you actually mean by this. If you're asking for
something that could be run from *within* the application section,
this is impossible with the AVR (except for a few ATtinys): *only* the
bootloader area (as designated by the respective fuse bits) is allowed
to write to flash.
If you're asking for something that can *update* the application flash
section: that's it.
