hi..i have a board with imx28 processor;i'm using ltib with kernel 2.6.35. i make boot from sd. i download the kernel via tftp and the last message in the serial port is the following:

 

....

VFS: Cannot open root device "nfs" or unknown-block(0,255)

Please append a correct "root=" boot option; here are the available partitions:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,255)

 

What could be the problem?

Thank you in advance

Do you have your root nfs directory setup correctly?

 

On my system it is /tftpboot/imx28/.... 

 

Where the imx28 directory has my entire system there.

 

It seems to me your NFS world is not setup correctly.

Do you have CONFIG_ROOT_NFS=y in your .config when building kernel?

 

Also what is your boot command line?

 

Option shown below in boot cmdline  works.

 

ip=192.168.137.1::192.168.137.254:255.255.255.0::eth0: root=/dev/nfs nfsroot=192.168.137.254:/tftpboot/,v3,tcp noinitrd
