Re: 8272ADS and Linux 2.6.12

Hello,

We have a MPC8272 Eval Board which came with Linux 2.4 and U-boot. We
wanted to move to 2.6. I downloaded the latest 2.6.12 sources and
compiled the sources for this platform. The kernel is built, have run
the mkimage tool, but the kernel wont boot.  It just hangs after
decompressing the image.

 

Any ideas  ? Anything different that needs to be done for 2.6 ? Or any
known issues ?

 

If you're using the u-boot that came with MPC8272 Eval board it may happen that BCSR is mapped differently in u-boot and the kernel 2.6. That's what happened when I tried to boot linux 2.6 on MPC8272ADS. Check the value of CFG_BCSR in u-boot/include/configs/MPC8260ADS.h and BCSR_ADDR in linux/arch/ppc/platforms/pq2ads.h

Thanks!
