Linux on a NCD Explora 450 Xterm

[Donovan, Chris]

I've got a NCD Explora 450 Xterm which I am trying to load up Linux on. The
Explora has a PowerPC 403CGX processor in it. During normal use the Explora
uses tftp to load an NCDware image from one of our servers.

I have compiled a Linux kernel configured for an Oak board. After I ran
"make zImage" I found vmlinux but I was unable to find vmlinux.img. There
were no errors indicating that there was a problem.

At this point, I'm trying to figure out how to take vmlinux and boot it on
the Explora. Both vmlinux and the NCDware image seem to be ELF executables
but when I try to load the vmlinux file onto the Explora via tftp I get the
following error: "Address out of range. File is bad or too large for
installed memory." The vmlinux file is much smaller then the NCDware file
and I get the same error even if I pad blanks on the end of vmlinux to make
it the same size as the NCDware file. I assume that this is not an
appropriate file to be loading to the Explora. Does anyone have any
suggestions for a way to go about creating an appropriate file? I'm
interested in developing this if someone can provide some guidance on how to
do it. Thanks.
