style='font-size:12.0pt'>Hi,<br>
<br>
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.<br>
<br>
And when I give kernel command string as init=/bin/sh , it says : <br>
>Failed to execute /bin/sh. Attempting defaults...<br>
[ 3.744035] Kernel panic - not syncing: No init found.
Try passing init= option to kernel.<br>
[ 3.768073] Rebooting in 30 seconds..<br>
<br>
--init is present in sbin/init which is a soft link to ../bin/busybox<br>
<br>
--I used powepc-405-gnu-readelf -h bin/sh to verify that it is compiled for
powerpc itself.<br>
<br>
Any other suggestions ?<br>
