2.6.24 for mpc8458amc

[-- Attachment #1: Type: text/plain, Size: 1877 bytes --]

Hi,

I am trying to make a 2.6.24 vanilla kernel boot (an work fine in a second
time) on a mpc8548amc board.
I have add the platform specific stuff from the sources of the current
kernel running on the cards.
What I have basically add is:
- a folder mpc8548amc, in the config/platform directory, which allow to
select the mpc8548amc as the supported platform
- add the following files:
  - arch/ppc/configs/mpc8548amc_defconfig
  - arch/ppc/configs/platforms/85xx/mpc_8548_amc.h and .c
- I have used the dts of an another platform (mpc8548cds) which seems quite
the same, but I haven't got any confirmation of that yet.

When I am booting the kernel image I get:

AMC=> dhcp 0x1000000 uImage.amc.2.6.24
Speed: 1000, full duplex
BOOTP broadcast 1
DHCP client bound to address 10.255.255.2

Hello Maxime,

if your board is still running, although you can't see the messages tha=
t
means you don't have any console. Try to set one (I think you can use a=
 SCM
of the CPM) in the kernel configuration (characters devices)  or in the=

command line (console=3D).

Anyway, if you want to be sure if the  kernel is booting up, look up th=
e
buffer where the messages are saved before the console is enabled. Find=
 the
function __log_buffer in the System.map file and throu the bootloader, =
have
a look at this address.

Uh, let's clear up minor confusion here.  Are you using
ARCH=ppc or ARCH=powerpc?  I'm surprised to see that there
is mention of arch/ppc/... above.  Are you sure this is an
ARCH=ppc build?  You won't need a DTS file at all then.

But if you are using a DTS file, and I suspect you should,
then this is ARCH=powerpc.

Did you download a DTB file and use it on the bootm
command?  Nope.

This is really a FAQ failure mode.  Are you sure
you have the console set up properly?  Any chance
you can get to the __log_buf with a BDI-2000?

Thanks for your answer,

I am going to check this ppc / powerpc things.
I should use the architecture powerpc, don't I?

I'm not really sure I have understand what do you want to do with a
BDI-2000.
I access the cards through a serial line directly.

cheers,
Maxime

ARCH == ppc is scheduled for _removal_ from the
entire Kernel source base is just about 4 months.
Feel free to move the deck chairs around. :-)

Perhaps, for starters, you read "Building Embedded Linux Systems"
as found here:
    http://www.oreilly.com/catalog/belinuxsys/

> I access the cards through a serial line directly.

Of course.  But when you get no information there,
you might try a different interface.

Hi again,

this time I have tried to compile the kernel, with an embedded compiler on
the board.
here is the result...

That's a bug in older toolchains, which is aggravated by a misguided 
policy that we build all wrapper platforms, always.  Either use a newer 
toolchain, or remove treeboot-walnut from arch/powerpc/boot/Makefile.

It would be good to know what versions of binutils and gcc are being
used though.

If you really have a mpc8548 than there is no CPM.  It has 16550 style  
UARTs on it.

Hi,

yes It has something like 16550 UART.
the compiler version is gcc-3.4.3 with some specific stuff for the platform.
I also have a gcc-4.1.2 vanilla which has been compiled with the previous
one. The 4.1.2 works if you tell it to emulate the floating point
instructions.

thanks Scott,
without the treeboot-walnut it compiled

I have still my first problem though:

AMC=> bootm 0x1000000
## Booting image at 01000000 ...
  Image Name:   Linux-2.6.24
  Image Type:   PowerPC Linux Kernel Image (gzip compressed)
  Data Size:    1802038 Bytes =  1.7 MB
  Load Address: 00000000
  Entry Point:  00000000
  Verifying Checksum ... OK
  Uncompressing Kernel Image ... OK

and nothing else...

Any idea ?

This may become from the fact that the uboot installed on the cards is old
and it apparently doesn't support the newer version of the kernel image...
(I have got that from an another mailing list)

cheers,
Maxime

Yes, you'll either need to look at updating u-boot and including  
support for the device tree in it or look at the cuImage wrappers in  
arch/powerpc/boot as a mechanism to boot a kernel w/an old fw.

Hi,

I have updated the uboot on the cards and get the same result

AMC=> bootm 0x1000000
## Booting image at 01000000 ...
  Image Name:   Linux-2.6.24
  Image Type:   PowerPC Linux Kernel Image (gzip compressed)
  Data Size:    1802038 Bytes =  1.7 MB
  Load Address: 00000000
  Entry Point:  00000000
  Verifying Checksum ... OK
  Uncompressing Kernel Image ... OK

No further messages...

However I have try to boot an image (2.6.23-rc6 from freescale) which has
been patched for my platform and it works.
Thus the problem is not coming from the uboot anymore, but from something
else.
I can't get the source from freescale to see what they have changed because
their is some other stuff (unrelated with my problem or even my platform)
that are confidential to them...

So what I am looking for here is a hint of where to look, an idea of what I
might have done wrong...

regards,
Maxime
