Swami, I suspected the Server, and checked the exportfs file and it was ok. Just to make sure I NFS mounted the same directory on a different dm355 board and it was succesful. Only in a particular board Im getting the problem. Well, even in this board it was working fine until sometime back when the board's ip was different. All this seem to have happened only after the ip addresses changed Is there a possibility of the server rejecting for a particular board(particular MAC id or so) Please help me on how further I can trouble shoot! Cheers, Deepak

DM355 EVM is contacting the NFS server but the server is returning error for the NFS mount.

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.
