Ramdisk Image is corrupt or invalid

[admin]

I am working with  layerscape ls1012a processor. Our code warrior license is Developer. For our custom board I am trying to build our own kernel and device tree. I have built kernel_fdt.itb. But when I try to boot my board with this kernel_fdt.itb, I get a failure message and it is Ramdisk image is corrupt or invalid . How to fix this error? Also I need to attach rootfile system with it.I don't know how to do it.I am giving my kernel_fdt.its code here
