I haven't tested this in a while so will try to get to it today on at 
least 4.6.

The script runtest in psim/tools has the procedure as of the last time 
it worked.
I suspect it has not been used since the BSP was converted to the new 
exception
model.

FWIW the shm and sem keys along with the size of the shared memory have
to match.  It is possible the startup procedure you are using doesn't 
completely
account for that.  The runtest script builds a device tree special.  
Hmmm... runtest
doesn't include the recent addition of the pvr setting.  Update your 
psim tools directory
and look at how it is invoked there.
