Hi ,
  I am facing a problem in mounting the nfs file system  with the new linux PDK1.4 on the imx31-3 stack board. I did have this problem with the old linux bsp and the redboot.
 
With the new PDK Linux version1.4 , i am facing problem in mounting the NFS .
 
I am giving the following command during the kernel boot up. 
 
 
exec -c "noinitrd console=ttymxc0 root=/dev/nfsroot rootfstype=nfsroot  nfsroot=192.168.1.84:/tftpboot/Disk-Tftp/rootfs ip=192.168.1.83:192.168.1.84"
 
(The NFS Server ip address is 192.168.1.84  and the imx31-3 stack board ip address is 192.168.1.83.)
 
The following error messages are coming on the hyperterminal
 
 
 
eth0: link down

When i check the  /var/log/messages    i did not find any request coming from the imx31-stack board for nfs mounting.
 
Could any one help what is the problem?
