Hi,

Yes I am using ARCH=ppc (actual line is $make ARCH=ppc CROSS_COMPILE=powerpc-405-linux-gnu- zImage.initrd ) for this I have placed ramdisk.image.gz in arch/ppc/boot/images. In case of ARCH=powerpc I cannot find processor type 405 , in make menuconfig. Thats why i am using ARCH=ppc.

And when I give kernel command string as init=/bin/sh , it says :
>Failed to execute /bin/sh. Attempting defaults...
[ 3.744035] Kernel panic - not syncing: No init found. Try passing init= option to kernel.
[ 3.768073] Rebooting in 30 seconds..

--init is present in sbin/init which is a soft link to ../bin/busybox

--I used powepc-405-gnu-readelf -h bin/sh to verify that it is compiled for powerpc itself.

Any other suggestions ?

Hi,

I am trying to boot ML405 with Linux source code downloaded from  
http://www.git.xilinx.com . My cross compiler tool chain version is  
gcc-3.4.1, glibc-2.3.2 and binutils-2.15. I have also downloaded RAMDISK  
from same url (http://www.git.xilinx.com). When I download  
zImage.initrd.elf using XMD everything goes fine, untill RAMDISK is  
uncompressed, I get following messages :

Try changing the kernel parameters line to specify init=/bin/sh and see
what happens.
