Hello All,

I am facing problem while NFS mout and boot from TFTP Server and client.

Could you please help he I am unable to find problem where it is occurring.

 

1) I have set it up tftpboot and tftp service also i added.

 

 -> tftp loading image.

2) NFS

 

server(Host Linux ip) - 192.168.1.34

etc/exports -

/tmp/fs          *(rw,sync,subtree_check)
/tools/rootfs    *(rw,sync,subtree_check)

 

3) for NFS mounting

sudo mount -t nfs 192.168.1.34:/tools/rootfs  /tools/rootfs   -->?

the above mounting step is right or wrong.

otherwise please help me.

4) current printenv
