1) Did you install the server using the nfs-server-config script?
2) Can you post your /etc/exports and and static map files you're using?

If you're able to mount the RFS, the only thing I could think to
suggest would be to look at your /etc/exports and make sure that
you're using a proper map file for your NFS export.  Try "man exports"
and look for the map_static section.  That may help you clear up
your permissions issues.

You might want to try and mount the exported RFS from a desktop linux
system; this will give you some idea of what permissions are being
translated incorrectly, and how you can go about correcting your
static map files to deal with them.

Sure!  Just not using Wind River's stuff :-)
