AMCC ppc440spe 2.6.23.10 kernel boot help

[Shubhada Pugaonkar]

Hi Wolfgang

I could get 2.6.28 version up and running after using device tree blob.
Also our customer is using Luan and our IT dept ordered Katmai. 

So looks like the problem is solved for now (basically my company needs
to look into alternative setups)

Thanks a lot for your prompt help.
Shubhada

You probably did not load (and use) the device tree blob which is
needed with recent (arch/powerpc based) kernel versions.

It looks broken to me for a Katmai board. Are you sure your customer
is also using Katmai?

This is obviously  an  old  setup  for  old  (arch/ppc  only)  kernel
versions,  and  heavily  crippl^H^H^H^H^H  modified  from the default
environment.  You  might  consider  to  restart  from   the   default
environment settings (probably even with a recent version of U-Boot -
your's is too old and does not include full device tree support).

On the other hand, I don;t see a reason why the old (arch/ppc based)
kernel should not boot - except that it might be misconfigured for
that board.

Did you try any of the released (and well tested) kernel images on
our FTP server? See ftp://ftp.denx.de/pub/linux/images/amcc/katmai/

Best regards,
