Ok, so all that worked - it WAS necessary to choose "[*] Default all settings
(lose changes)" in order for it to work though. Without this option checked I
needed to add information and variables and constants and definitions that were
not added into necessary files after make menuconfig and make dep were
completed.
But I still have nothing working with the ML310 board. I did a "dow
image.elf" at the XMD command prompt, then "con" and it showed up with a
"RUNNING>" prompt, but nothing showed up on the hyperterminal window. I
compiled using 115200 baud and I changed my hyperterminal to match this, but
nothing shows up ...at all. Where do you think I would need to start looking
to resolve this issue?

After generating a new auto-config.in using the BSP,
you'll need to:
0. put new auto-config.in into kernel directory
linux-2.4.x/arch/ppc/platforms/xilinx_auto
1. change to the top uClinux-dist directory
(*NOT* the kernel directory)
2. In "Vendor/Product Selection --->"
Choose "Xilinx"
Choose "powerpc-auto"
3. In "Kernel/Library/Defaults Selection --->"
Choose linux-2.4.x as your kernel, making sure that
this is a symlink to or copy of the linuxppc-2.4
tarball from UQ.
4. In "Kernel/Library/Defaults Selection --->"
Choose "[*] Default all settings (lose changes)"
5. Save and quit..
This process will pull in default Xilinx/powerpc config
files from vendors/Xilinx/powerpc-auto/config.*
for the kernel and for other uClinux components.
It will also generate a new linux-2.4.x/.config
based on your auto-config.in and the defaults
in vendors/Xilinx/powerpc-auto/config.linux-2.4.x.
btw, I don't have an ML310 board. I have however gotten
the UQ kernel + uclinux to work on a v2pro FF1152 board
and a virtex-4 FX-12 minimodule.
another btw, the linuxppc-2.4 code has an auto-config.in
inside it which, if you follow the above steps (without
doing step 0), should compile. The supplied auto-config.in
won't match your board, but it should at least compile.
