Re: 8272ADS and Linux 2.6.12

Thanks all for the replies and help. I have the 2.6 Kernel running
now. Here are few of the things that i did to make it happen:

1: make ads8272_defconfig
2: edit .config to add the follow:
CONFIG_SERIAL_CORE=3Dy
CONFIG_SERIAL_CORE_CONSOLE=3Dy
CONFIG_SERIAL_CPM=3Dy
CONFIG_SERIAL_CPM_CONSOLE=3Dy
CONFIG_SERIAL_CPM_SCC1=3Dy
CONFIG_SERIAL_CPM_SCC2=3Dy

3. In u-boot, set the bootargs to
bootargs=3Droot=3D/dev/ram rw console=3DttyCPM0,115200

4.Modify the file arch/ppc/platforms/pq2ads.h,
// #define BCSR_ADDR            ((uint)0xf4500000)
#define BCSR_ADDR ((uint)0xff080000)

Thanks!

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
