Thanks for your reply.I tried to transfer it directly but no luck.
I have downloaded kernel from this source (git clone git://
git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git) and
compiled it.
when i directly boot the kernel (sudo ./usbboot aboot.bin zImage )it hangs
with following serial output:
[ aboot second-stage loader ]

MSV=00000000
jumping to 0x82000000...
Uncompressing Linux... done, booting the kernel.
Warning: Neither atags nor dtb found

I dont know whether my image is having some problem ???
Please suggest.
