First of all I highly recommend a careful study of the MSP430 and the 
ATmega128 specs. The two architectures are quite different and they have 
different limitation.

In tosboot the writing is done using a component called ProgFlashM.nc. 
There is one in tos/lib/tosboot/msp430 and another one in 
tos/lib/tosboot/avr. The function that is using it is the programImage 
from TOSBootM.nc from tos/lib/tosboot.
