It stops here.

Is the any problem in making kernel image or any specific reason.

Suggest me

1) Is your initrd valid?
It should either be an initramfs newc cpio archive (optionally compressed) with a /init executable file, or a fs image (e.g. cramfs) with a /sbin/init executable file.
2) Is your ramdisk big enough to contain it?
You may have to set ramdisk_size on the kernel command line.
ramdisk_size=12M

I checked the above mentioned config.

Memory allocated for Kernel is only 64MB

I have video driver which capture image of HD resolution.
My ramdisk size after unzip is 32MB
I increased the memory allocated to linux by 82Mb and it works now.

Thanks for suggestion.

Kirthika
