AMCC ppc440spe 2.6.23.10 kernel boot help

[Shubhada Pugaonkar]

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
