Trouble setting up NFS for i.MX53

Hello,

I'm been trying to setup the i.MX53 to boot via NFS but having some problem.  Here is what I did and maybe someone can point out what I did wrong and how to fix it.  I'm pretty new with this so any help is greatly appreciated. I used the Adeneo 4.1 prebuilt files to build this setup.

 

Here is my IP info, using an Apple Ethernet Adapter

eth1 Link encap:Ethernet HWaddr 28:37:37:03:c5:f1

inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0
