Hi,
First time iam porting linux kernel 2.6.12 on MPC8540(PIC) board.In
platform code i have set the CCSRBAR to 0xff70 0000 which is the
default value for 8540. it gets hanged at "Uncompressing kernel image...ok".Iam
using u-boot-1.1.2.
Should i edit anything in .config file?
Thanks and Regards
Revathy

Hi,
I am able to boot linux kernel 2.6.12 on ppc 8540, and also able to login
too. But then i am unable to see any output when i say ls, mount,ifconfig
etc. Only pwd and env seem to work
Whereas if i boot with kernel 2.4.20 and with the same ramdisk which i
used to boot 2.6.12, i am able to see eveything, ls, mount outputs etc.
I built the ramdisk image using busybox 1.2
This is the boot messages of 2.6.12 :

Welcome to Linux on MPC85xxSK board!
MPC85xxSK login:
-> After this i login as root and type ls but no output on the screen, pwd
and env throw output.
-> I also see that in 2.4 booting messages :"Freeing initrd
memory........" is displayed" but not in 2.6.12, eventhough i have enabled
CONFIG_BLK_DEV_INITRD
-> Should i enter something for CONFIG_INITRAMFS_SOURCE as of now it is
blank ?
Thanks and Regards,
Prashant

Do you have console=3DttyS0 on the command line to the kernel?
