boot linux kernel error
so i brought a development board(FriendlyARM mini2440),i have compiled the linux Kernel many times.
also it all doesn't work.
when i compiled the linux Kernel(linux-2.6.29) to a zImage and downloaded to board.
at the same time the rootfs.img download to board.
when boot the kernel it show that "Root-NFS: No NFS server available, giving up." ,"VFS: Unable to mount root fs via NFS, trying floppy."
"VFS: Cannot open root device "mtdblock3" or unknown-block(2,0)"
how can i do to this problem?
At last thanks for you spent the time to read my questions.

- I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
You must have it configured to mount an nfs share for your root file system. I do that with my ARM development board. You have to be sure your host has exported the appropriate directory tree for that, and that permissions and such are appropriately configured.Sometimes, real fast is almost as good as real time.
