Hello:
Now I can boot kernel both from Network or from Flashrom. But there are
problems.
[boot from Network]
When I download the kernel via TFTP at 0x400000 ,then go there to run
it:
.........
VFS: Mounted root (ext2 filesystem).
Freeing unused kernel memory: 28k init
As you see here, occasionally it can not even show the bash prompt
"bash#", and at this time any input on the Win98 SuperTerminal has no effect.
But most of the time it can show "bash#", and at this time I can do
"ls" "cd" etc, but after a certain time when I type any commands ,the Win98
SuperTerminal doesn't response and cannot show the character I just type any
more. It seems that it cannot receive input via SERIAL port.
And If I run an application which will print some debug information all
the time , it will also hang after a certain time(But it should not so in
theory).
So I suspect either the kernel is not stable or something is wrong with
my bootrom.
The kernel I use is MPC8xx-2.2.13, I have modified it to suit my
purpose(uart.c enet.c). But
to my surprise, When I use VxWorks bootrom to TFTP download the same kernel
and
run it, it doesn't have all the above problem. It works well. So the kernel
should be stable.
[Boot from flashrom]
It has the same symptom as the above.
Does someone has similar problem? and what's the solutions?
Another question I want to ask is: When you download the kernel via
TFTP or copy from flashrom to RAM 0x400000 , Do you do SOMETHING SPECIAL ELSE
(about 860) and then jump there 0x400000 and run it, Or do you DIRECTLY jump
there 0x400000 and run it?
Can you give me any suggestions?
Thanks very much.
dony

Mot SPS is trying to migrate to a One SPS Website, which is
supposed to be mot-sps.com. They took a snapshot of our website
many moons ago. Of course, while changing the look & feel,
they also want to change the backend and (our) interface to the
servers. Used to be two servers, one internal and one external.
You did a "Magical Mirror Command" on a Unix box to make the
external the same as the internal. Now there are three different
servers, the internal, a "staging" server, and the external. I
still don't quite have it figured out, but I do know that
www.mot.com inside the firewall does NOT correspond to www.mot.com
outside the firewall. On top of that, instead of just letting
us store documents in a .html directory, like sane people, they're
trying to do some kind of Mother of All Document Repositories,
with Magical Automagically Generated Pages, yada yada.
And on top of that, they're making us change to Outlook from
Netscape, and foisting Siebel on us. #include <big long anti-MS

Did the URL I give not work? Fscking 34@!$%#$@^%$#@%^
I'll try it from home and see if it does or doesn't work.
The patch we have should be updated from the previous one. The
old one had problems when the CPM was heavily loaded. This one
is supposed to be nicer to other CPM tasks.

Would you like me to email the package to you?
