[U-Boot] Problem with uboot booting Linux image

[Rahanesh]

Hi All,

I am trying to boot Linux from uboot.  I have cross compiled Linux and 
ramdisk for my board. After cross compilation i did a tftp to download 
the image(Linux + Filesystem) to RAM(0x80800000) . From there i copied 
it to flash(0xad040000).

Now on a reset u boot comes up and then when trying to bring LINUX it 
throws an error saying

Verifying Checksum.......Bad data CRC.

Then uboot prompt appears.

This is what happened.....
