I attached my uEnv.txt file I use for NFS. Make sure you change the IP
address and <userID> for nfsroot to match your host IP and userID. My local
network uses an address 10.100.116.xxx. My BBB is 10.100.116.104 and my host
is 10.100.116.73.
You need to install nfs-kernel-server on your Ubuntu host
Add the following line to your /etc/exports file on your host
/home/<userID>/targetNFS
10.100.116.0/255.255.255.0(rw,insecure,async,no_wdelay,no_root_squash,no_sub
tree_check)
Place your rootfs in /home/<userID>/targetNFS on your host
sudo service nfs-kernel-server restart
I think that is all, so NFS should work for you. I hope this helps.
Regard,
John
