Please show me which U-Boot document uses 0x00400000 as load or entry
point address so I can fix this immediately. It is WRONG and CANNOT
work.

Please start by giving a precise description of what you did. and
which error messages you got.
You "get an exception" - when? When running "mkimage"? When booting
the kernel? Which sort of exception? What is the exact error message?
Please include a complete log of your actions and all output.

Wolfgang Denk

I take the "step" from u-boot's README file only. Because I got an
exception, I try to load it to other address. I use 0x00400000 because
zImage seems to be loaded at there....anyway, just a guess.

Maybe I do something wrong before. Now, it just hangs. Thanks your
suggestion about the load address.

I trace the code in kernel and I found some strange behaviors.
In the first case (using walnut_config provided in kernel source),
kernel hangs at mapin_ram();
However, if I turn off all unnecssary options and leave only serial
console, my kernel can run until init/main.c: kmem_cache_init();
As both hangs in memory related function, I tried to run a memory
test on my board in u-boot. But it hangs.
=> mtest 0 3ffffff
Pattern 00000000 Writing...
<hangs>
I tried smaller range (ffffff), it still hangs.
I am sure my board's memory is in good condition because VxWorks can run
very well on it. Have any idea? Thanks.
Best regards,
Jacky

Sorry, it should be sti() just after kmem_cache_init() instead.

The official 2.6.7 kernel works just fine on ppc machines.

Please define "ppc machines". It doesn't work on most of the systems
we have in the lab (like MPC8xx or MPC5200 etc.)

The question was: "Is there a linuxppc-2.6 kernel tree or are they
still using the linuxppc-2.5 tree?". "They" isn't a good definition
of what machines (or people ?) he was referring to. I guessed he
meant the majority of ppc machines.

Indeed. Not all "PPC machines" are Apple MacIntosh systems, although
Macs do use the PowerPC CPU. Too many folks simply equate the two...

Then send patches upstream. It's plain wrong to reproduce what we
had in 2.4 letting all sort of stuffs pile up in the "ppc" trees
that never get sent upstream.
I tend to think that pretty much everything including fancy board
support should be sent to lkml for comment & proposed upstream right
away.

There was a fair amount of MPC5200 code merged recently. MPC8xx
apparently isn't far off working either.

Amongst the "PPC machines" on which I have 2.6 running are mpc8265,
mpc8560 and a dual 745x machine with MV64360 chipset -- although the
latter isn't merged into Linus' tree yet.
It's not _just_ working on macs.

Recently the kernel version on the github
repository did not match up with the master branch of
https://kernel.googlesource.com/pub/scm/linux/kernel/git/powerpc/linux
Specifically, github was hosting v4.10-rc5 while master had
v4.10-rc8. All the while Linus' mainline was at v4.11-rc1.
Was this an anomaly or is there a technical reason please? While
writing this I see that perhaps I should have checked the other
branches (fixes, next, test).
thanks,
Tobin.

These are all managed by different people, and none of them are managed
by any of the linuxppc-dev folk.
Sorry I can't be more helpful.
