What specific problem are you facing in monunting nfs (error messages and the procedure you are following to mount nfs)

What is your kernel version and on which board are you working

Hi, all,

I have problem in mouting nfs in my target board. My nfs server works very well, and I tested using other computer (no firewall problem). My linux kernel is 2.6.22, and nfs is included in the compilation.

when I mount it:
mount -t nfs 192.168.0.99:/.. /..

I got the error message:

mount: wrong fs type, bad option, bad superblock on 192.168.0.99:/home/rumi/nfsroot, missing codepage or helper program, or other error (for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.<type> helper program) In some cases useful info is found in syslog - try dmesg | tail or so


Some people said nfs-common package are required. But the thing is, I don't know how install it in target board (no Apt-get in linux kernel).

I don't use nfs for root, is it a problem?

Any suggestion is highly appreciated.

I mount my rootfs using nfs at the boot time using the instructions given in
the book "building embedded Linux Systems" by Karim Yaghmour.

my bootargs is set as

mem=64M console=ttys0,115200 root=/dev/nfs rw nfsroot=10.1.0.43:/tftpboot/rootfs ip=10.1.0.44

There is an advantage of mounting the rootfs using nfs as I donot need to flash the new softwares to the nandflash, of course the same is in your case.

I just build the softwares using bitbake and copy the .ipk file to the mounted rootfs
folder on my pc. This way it also gets reflected on the rootfile system of the board
and I install it using the ipkg command.

you can do one thing download the software you want to install from the
http://www.angstrom-distribution.org/repo/
copy it to a pen drive, attach the pen drive to your board and mount it

to install .ipk package the command is
ipkg install <package name>

for more info. on ipkg refer

thanks.
