RE: [Ltib] Old uImage Won't Boot

[Reer, Carolyn (SA-1)]

Hi Stuart:
My host /etc/exports file is:
/tftpboot/ltib 192.168.1.100(rw,no_root_squash,sync)

/tftpboot/ltib is a link to the root file system
/tftpboot/ltib -> /home/vrams/mpc8536ds/ltib/rootfs

I also changed /home/vrams/mpc8536ds/ltib/rootfs/etc/exports file to:
/tftpboot/ltib 192.168.1.100(rw,no_root_squash,sync)

But that didn't help

Hi Carolyn,

Make sure you have the right export permissions on your NFS server.  For
example, make sure you have no_root_squash listed in the options.

You can verify this independently by mounting the rootfs on some other
machine and trying to touch a file somewhere on that filesystem.

Regards, Stuart
