Uploading problem in OSK5912

[naga rajan]

Hi,

 While mounting the filesystem using NFS, the following error occurred. DHCP
configures the IP address properly(192.168.0.150). What could be the
problem?



Looking up port of RPC 100003/2 on 192.168.0.121

Looking up port of RPC 100005/1 on 192.168.0.121

Root-NFS: Server returned error -13 while mounting
/tftpboot/serverip:/home/sach

in/montavista/filesys

VFS: Unable to mount root fs via NFS, trying floppy.

VFS: Cannot open root device "nfs" or 02:00

Please append a correct "root=" boot option

Kernel panic: VFS: Unable to mount root fs on 02:00



Please provide a solution for this problem.
Thanks in advance,
B.Nagarajan,
SANDS.
