You better should not use the flash for such purpose, since you could
override your application code. If you still wand to do so, have a look
to the eboot bootloader. I also could send you a flash-routine that you
can use to write to application flash on runtime. Reading is then done
by the program space string utilities.

Better use the eeprom. Have a look to avr-libc (if you use gcc) or
implement writing to the eeprom by hand... Have a look to
NutSaveConfig / NutLoadConfig.

Bye,

Ole
