Support for MSP430X

Hello everyone,

My research team is interested in porting RIOT OS to MSPSim for our research on RPL. Because of our need to use a device with more RAM and flash memory, we have chosen to port it for the MSP430 EXP5438 board because that is the only board that meets our specifications.

We used the latest MSP430-GCC compiler provided by SOMNIUM (version 5.0.0) to compile RIOT. Unfortunately, we have encountered some problems. So far, we made RIOT work with threads, SPI, and UART. However, we are now stuck with making ISRs work since the program calls an illegal PC on ISR entry (0xFFFF).

Is there anyone who did the same thing and may have code to share with us?
