RE: AMCC ppc440spe 2.6.23.10 kernel boot help

Hi Wolfgang=20

Thanks for quick response.=20

I am kind of helpless regarding the kernel version, as our customer is
using it and I need to replicate their environment. I just tried 2.6.28
with katmai_defconfig file and still face the same problem.=20

The config file that I sent before is provided by the customer. It is a
working configuration for them.=20

The exact board that I have is Katmai.

I verified that I am using serial port 0. I tried to set bootargs to
just console=3DttyS0,115200 and I don't see the kernel booting. =
Everything
in env variables seems ok to me unless something trivial is missing my
eyes.=20

My sequence for boot is=20
=3D>tftp 0x1000000 uImage-ppc
=3D> run flash_nfs (I have done this manually also)=20

my printenv output is as follows.

Thanks for your help
Shubhada

I am trying to bringup AMCC ppc440sPE  board with 2.6.23.10 kernel

2.6.23.10 is very old. Please use current code. 2.6.23 was long before
the switch to arch/powerpc, so all the efforts you are spnding now on
this old stuff are really wasted.

Use at least 2.6.28 or later.

kernel.org. My .config file is attached. I used ARCH=3Dppc and

Why don't you start with a good, known to work kernel config file
like 44x/katmai_defconfig ?

For example, you mention a 440SPe processor above, but your config
file seems to be derived from a Luan board, which is 440SP (not SPe)
so there is not much surprise if it doesn't work.

CROSS_COMPILE=3Dppc-linux- (also tried ppc_4xx-) and did 'make =

uImage',

but unable to boot into the kernel. My nfs and uboot settings seem to

be

correct. The kernel gets stuck as shown below. Any help appreciated.
Please let me know if any more information is required.

In the first place, please use current code.

Second - which exact board is this? Katmai?

=3D> run flash_nfs

What exactly are your environment settings? Which exact value of
"bootargs" do you pass to Linux? Does it include a valid console=3D
argument?


Best regards,

Wolfgang Denk
