EVM437x NFS rootfs problem

I have problems when trying to configurate NFS rootfs to Uboot with this setup:
- EVM437x
- VirtualBox Xubuntu with USB<-->Ethernet converter, static IP 10.0.0.0
- Sitara Linux SDK installed
- uboot in SD card
- kernel from VirtualBox using tftp (<-- working!)
- rootfs from VirtualBox using NFS  

I get the "RPC call returned error 13" when kernel is trying to mount the rootfs. I think that is "access denied" error?
Everything seems to be ok in the VirtualBox, see below:

sudo service nfs-kernel-server status
nfsd running

sudo exportfs
/targetNFS        <world>

I have tweaked these Uboot variables...
bootargs=console=ttyO0,115200n8 root=/dev/nfs nfsroot=10.0.0.0:/targetNFS,nolock rw ip=10.0.0.1
netargs=setenv bootargs console=ttyO0,115200n8 root=/dev/nfs nfsroot=10.0.0.0:/targetNFS,nolock rw ip=10.0.0.1
rootpath=/targetNFS

... with this result:
[    4.253219] IP-Config: Guessing netmask 255.0.0.0
[    4.258630] IP-Config: Complete:
[    4.262112]      device=eth0, hwaddr=34:b1:f7:30:de:9b, ipaddr=10.0.0.1, mask=255.0.0.0, gw=255.255.255.255
[    4.272593]      host=10.0.0.1, domain=, nis-domain=(none)
[    4.278501]      bootserver=255.255.255.255, rootserver=10.0.0.0, rootpath=

It looks like the rootpath is not passed correctly from the Uboot bootargs to the Kernel (empty string in "roothpath=" ).

Any suggestions?

Brgds,

M.T.
