No, you do not _have_ to use NFS, but it is a lot easier than using a
RAMDISK when your developing apps.

How exactly are you loading the kernel/ramdisk image?

I'm not sure what is causing this, was the image corrupted when you
downloaded? Maybe someone else can help us here..?

Your boot options should have root=/dev/ram0

I used one of the Denx ramdisks with no problems and didn't need to
rebuild anything. I didn't build a unified kernel/ramdisk image though,
I just loaded the kernel and then the example ramdisk unchanged. Try that.
