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 :

--I was doubtful about busybox version used in RAMDISK provided at git
site. So I compiled my own busybox-1.10.3 with my cross compiler tool
chain still I am facing the same problem. Can anybody guide me.
The problem is that the kernel can't find the init program. Check out
it, does it exist? You can use init= kernel option to specify a new
position other than the default one, if it's in a specific folder.
