Please read the section on how to enable Jffs2 in the kernel - make menuconfig, filesystem, check for MTD if flash driver is enabled etc.. 

If u dont have jffs2 available consider using ramdisk option too if ur filesystem is small and you dont care about files generated/modified after bootup.

Hi Nagarajan,

I Use something as follows:

setenv bootargs 'mem=32M console=ttyS0,115200n8 noinitrd root=/dev/nfs
rw nfsroot=<serverIP>:<MntPath>,vers=2,rsize=1024,wsize=1024 ip=dhcp
devfs=mount'

for a 2.4 kernel.

Check if you are able to do a "mount -t nfs '<serverIP>:<MntPath>' -o
'vers=2,rsize=1024,wsize=1024'" from another linux box. If this works,
then the above boot args should work.

Note: the vers argument is needed for some nfs servers..

Regards,

Nishanth Menon

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.
