2.6.24 for mpc8458amc

[raul.moreno at telvent.abengoa.com]

Hello Maxime,

if your board is still running, although you can't see the messages that
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=).

Anyway, if you want to be sure if the  kernel is booting up, look up the
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.

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

No further messages...

Does someone has an idea ?

thanks,
Maxime
