mp application for powerpc-psim does not work!

[Bert]

Thank joel first!
I use the script c/src/lib/libbsp/powerpc/psim/tools/psim as follows:

sh psim base_mp-node1.exe

but still failed, it said:
attemp to attach unknown device shm.

Here is the question:
How can i get the needed device "shm and sem"?
