Need Help with i960 simulator

[Jim.Montville@nokia.com]

I'm trying to use the i960 simulator that came with gdb-5.0, and I believe I
have it all configured and built properly (--target=i960-sim-coff), but I
have some fundamental 'newbie' issues:

1. I know that I have to define memory regions to the simulator, but I
haven't a clue how to do this from within gdb. Without memory regions
defined, I can load a i960 coff executable, and specify 'target sim', but if
I run or single step, I get a segmentation fault.

2. I have been somewhat successfull with run.exe which was built when I
built gdb. That's where I learned about the options to i960 sim,
specifically the --regions command line option.

Am I on the wrong track with trying to use the i960 sim from within gdb?
Does i960 sim only exist as a standalone application?

Thanks in advance. Any help that anyone can offer will be appreciated.
