I have v3 client enabled, but didn't use it so far. Following your
suggestion, I've changed my u-boot settings:
U-Boot> setenv nfsargs setenv bootargs root=/dev/nfs rw
nfsroot=\${serverip}:\${rootpath},rsize=2048,wsize=2048,tcp,nfsvers=3
It works, though looks like version is still 2 (I'll check my server):
# mount
/dev/root on / type nfs
(rw,v2,rsize=2048,wsize=2048,hard,tcp,nolock,addr=192.168.0.141)
/proc on /proc type proc (rw)
none on /var type ramfs (rw)
none on /etc/config type ramfs (rw)
Thanks,
Leonid.
