Kernel configs to boot from NFS

Hi Everybody,

I’m facing a simple problem while I’m trying to boot from NFS. I used demo kernel (2.6.29) from Arago project and I could successfully boot from NFS. Then I downloaded source codes from git repository using 2.6.28-oe-r8 branch. After using uImage that I created by compiling 2.6.28-oe-r8, I could not boot from NFS.

I was searching the difference by checking options in .config file but I could not figured yet. Could you please help me to understand which options I need to turn on in order to boot from NFS ?

current NFS options in my .config
