Hi Peter, I have managed to get it to compile on Ubuntu 10.10 without problems.
I have some issues with a FreeRTOS project I have. 1. I need a naked interrupt routine, bacause the tic routine is an interrupt, and must push and pop the regs in a known way. I removed the condition to stop this, in msp430-functions.c no problem. 2. For some reason which I have yet to find, the processor gets to location 0x0000 and stops there. I'm using msp430-5438 I like the clean up around crt0.S.
