Lalalandrus over at the 430h forum shares his experience debricking a WRT54G router with a MSP430 Launchpad:
I ported the code to a MSP430. Changing pinouts should be relatively straight forward in the DEFINES. . The router is fixed but took literally days, backing up the 128k CFE took three days even though I didnt need it. Wrtiting is a little faster at one-ish day.
