Hello,

I'm just starting my experience of ARM-57TS-LPC3250 and LTIB. Trying to 
implement file system in NFS, I'm able to obtain a fully functional OS 
on the board, but during the boot kernel and root filesystem mount 
process I got some issues with the nfs server:

nfs: server 192.168.100.84 OK

         Welcome to Future Designs, Inc. LPC3250 Linux

The default password for the root account is: root
please change this password using the 'passwd' command
and then edit this message (/etc/issue) to remove this message

nxp login:

This just delay the mounting process, because at the end the system 
works, but I want to delete this issue.

Any ideas?
    

Well there are multiple possibilities, the following may give some ideas:
http://nfs.sourceforge.net/

Personally, I use " root=/dev/nfs rw nfsroot=<IP>:<DIR>,wsize=1500,rsize=1500" where "<IP>" is the NFS server IP address, "<DIR>" is the directory on the NFS server to mount as the rootfs.  Limiting wsize/rsize to 1500 helps to keep UDP fragmentation to a minimum.

Best regards
