[U-Boot] Problem with uboot booting image

[Rahanesh <rahanesh@tataelxsi.co.in>]

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.....
