Deepak,
Pl. ensure that your NFS configuration at the NFS server is
correct. DM355 EVM is contacting the NFS server but the server is returning
error for the NFS mount.

Swami

Subject: Unable to NFS mount in dm355
Im not able to do NFS mount in dm355 evm board.
I have tried stopping iptables, exporting exportfs configuration, restarting
portmap and nfs.
The board was working well until 2 days ago when my host had an ip address of
10.100.135.213.
Now due to some changes(!!! donno what exactly) the ip address of the host
became 10.100.135.173 after then it was not working.
I have changed the nfshost address in the bootargs. Also with the same host Im
able to nfsmount the /workdir/filesys on another dm355 eval board!
Could someone please help me to resolve the issue in booting?
Here is the startup log.
