If you want to execute programs directly from the simulator then you
need Mark's toolchain not Rich's. If you want to use Rich's toolchain
you have load the Linux image that is provided with Rich's toolchain and
to use the sim.cfg that Rich includes in his toolchain. If you use
Mark's or32-elf toolchain you can create programs that execute directly
from the simulator and you should use this sim.cfg that is provided in
this hyperlink http://www.geocities.com/dimitrisorfanos/sim.cfg.gz
