Hi all,

I'm trying to build a full Linux environment on a Virtex4 FPGA board.
I'm actually using a sparc's clone (LEON).
I've successfully built and run the system using grmon
grmon> load image.ram
grmon> run

But when it comes to mount the root filesystem over NFS, i get the
following error :

IP-Config: Complete:
     device=eth0, addr=, mask=, gw=,
     host=houat, domain=, nis-domain=(none),
     bootserver=, rootserver=, rootpath=
Freeing unused kernel memory: 5060k freed
Initializing random number generator... done.

I have checked my NFS server : it works fine, i can mount after boot
without any problems :
mount -o nolock -t nfs ip:path mountpoint

Any ideas please ?
Thanks a lot for your help
