Hi folks,
I am a beginner with the DaVinci DM8168 and in this forum.
We are using a DM8168 platform with software ezsdk_5_03_01_15. Our development platform is a Ubuntu 10.04 running in Vmware.
At the moment we do the first steps with this device.
I compiled the Linux kernel success and loaded the kernel via Tftp right.
But when Boot with NFS,we get a error.We have a NFS server (nfs-kernel-server) running on our host.
Here is the log, the Uboot settings:

this info 'VFS: Cannot open root device "nfs" or unknown-block(2,0)' show the linux kernel may not support nfs module,but i find the all nfs related option selected, but i don't know why '/dev/nfs' don't exist
I need help! Thanks!
Best Regards!
