Dev Board: LPC3131 board
Dev Host Environment: Ubuntu 10.04
Using LTIB...
Hi,
Need advise, I'm trying to accomplish an NFS mounted root filesystem setup but i'm having problem during the mounting of the filesystem on my target board. See the portion of the error i got below.
Looking up port of RPC 100003/2 on 192.168.0.101
Looking up port of RPC 100005/1 on 192.168.0.101
Root-NFS: Server returned error -13 while mounting /home/raul/ltib/rootfs

Has anyone encounter this problem before?
Anyway, i'm using a JFFS2 filesystem and 2.6.33 Kernel.
I also notice when i restart the NFS server on my Host i got a warning something like,
"exportfs: Warning: /home/raul/ltib/rootfs does not support NFS export."
I don't what this warning means, i just ignore it. I was thinking this might be the cause of the issue or maybe not...
Hope someone could help me with this issue... Thanks
regards,
Casper
