I wrote a little guide for hardware debugging with Eclipse using my makefile toolchain as the backend.
If you have a makefile environment with most CortexM3 or most MSP430 you could use much the same guide to set up hardware debugging.
There is a blog post with similar info to this post and links to the docs:
http://teholabs.com/2011/10/eclipse-har ... ing-guide/ (http://teholabs.com/2011/10/eclipse-hardware-debugging-guide/)
If you have problems with the guide in addition to the contact form and comments on the teho Labs blog you may post them in this thread.
