Dear Wade:
Since the MontaVista engineers have no clue as to how to use their product, and
I had the same experience, the appropriate solution is to abandon their product
until and unless they do have a clue as to how to use their IDE.
The route using DDD/gdb is an appropriate one and building an .elf file is no
problem with either uboot or Linux.
Another thing to watch out for with Montavista is their gdb executable may or
may not work correctly. If this is the case, you will need to get a gdb from
gnu.org and cross compile it. Basically, they blew it on the toolchain also.

Montavistadevrocket
Thanks!
I did indeed mean to say "devrocket" when I said "MontaVista"
I went down the DDD/gdb route using the MontaVista command line tools.
Their ppc_405-gdb connects to the abatron bdi2000 as a gdb server. I was able
to get that to work to some extent.
I did not ask my main question correctly enough. Let me rephrase.
My main question (for the MontaVista experts out there) is either
1) In DevRocket, what kind of project do you choose to debug an externally
build .elf file?
MontaVista support engineers had no clue.
or
2) How do you use DevRocket to create a cross compiled set of code linked
to a specific address.
MontaVista support engineers also had no clue on this one.
If either answer is no, OK.
Now that I have the DDD/gdb/Abatron complex working, I don't think I
absolutely need the DevRocket and its nice (but slow) facilities. It would be
nice to do the cross compile under DevRocket, but the Xilinx EDK is doing just
fine.
I will look into uboot later, when I do another attempt at getting linux
into the system.
I failed to mention that we have the system ace chip with a compact flash
card, and it is apparently functional. It provides all the "flash" that we
need. We do have some onboard flash for configuration data.
Our project is simultaneously complex and simple. It is complex in what it
does ( a complicated receiver based on latest DSL technology), but simple in
the household chores (linux is almost overkill, but we do need ethernet and all
that implies).
Interesting we can get PPC linux into 16 meg. Once that happens, I'll try it
again.
thanks,
wade

Writing custom bootloaders is nontrivial. Are you sure you really want
to do that?
And what does MV have to do with the bootloader?
