Hi 

 

I am trying to bringup AMCC ppc440sPE  board with 2.6.23.10 kernel from
kernel.org. My .config file is attached. I used ARCH=ppc and
CROSS_COMPILE=ppc-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.

Hi Steve

 

Thanks for your reply. I compiled the kernel.

But I can only load a kernel which was configured for the ppc
architecture

make -j2 ARCH=ppc CROSS_COMPILE=ppc_4xx- 

O=../build-linux-sequoia-DENX-v2.6.23 

sequoia_defconfig

 

If I pass

make -j2 ARCH=powerpc CROSS_COMPILE=ppc_4xx- 

O=../build-linux-sequoia-DENX-v2.6.23 sequoia_defconfig

the board hangs after 

 

    ## Booting image at 00200000 ...

       Image Name:   Linux-2.6.23

       Image Type:   PowerPC Linux Kernel Image (gzip compressed)

       Data Size:    1461799 Bytes =  1.4 MB

       Load Address: 00000000

       Entry Point:  00000000

       Verifying Checksum ... OK

       Uncompressing Kernel Image ... OK

 

I passed the same arguments to the kernel as before. Do I have to
specify 

something different? For the kernel? or a u-boot parameter?

 

Thanks in advance for your help

 

Best regards

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.

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.

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

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

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/

Wolfgang Denk

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.=20

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
