Here we try again.

When I boot I run 'run nfsboot'.

I make the image like this:
mkimage -A ppc -O linux -T kernel -d vmlinux -C none -n "uImage" uImage
I don't see the (required) "-a" and "-e" options in your call to mkimage...
I didn't know they were required. How do I figure out what they should be?
Unfortunately my board boots like this:
Like this? What is "this"? You don't shouw us which exact boot commands you used, nor what your environment settings are.
How are we supposed to help you without all this important information?
## Booting image at 01000000 ... Image Name: uImage Image Type: PowerPC Linux Kernel Image (uncompressed) Data Size: 4242375 Bytes = 4 MB Load Address: 00000000 Entry Point: c000000c
^^^^^^^^^^^^^^^^^^^^^^^^^^^
Where is this coming from?
Verifying Checksum ... OK OK
If boot time plays a role, you might consider turning off the checksum verification - which will take a looong time on an uncompressed kernel image. See "verify" environment variable.
And that was it :-(
No big surprise if you jump right in the middle of nowhere...
it boots fine, so I think that my vmlinux/vmlinux.bin.gz image is fine.
No, it is not.
que? please explain.
