[U-Boot] Kernel boot halts with "Verifying Checksum ... Bad Data CRC"

Hi,

I'm not sure if this is specifically related to u boot.

I have compiled a linux kernel, which if I run on a system with flash memory with 256k sector size there are no problems, however if  I rebuild for a system using flash with 64k sector size the boot process halts with the following errors

 Booting image at 00060000 ...
## Copy image from flash 00060000 to ram 00200000 ...
   Image Name:
   Image Type:   ARM Linux Kernel Image (uncompressed)
   Data Size:    1759300 Bytes =  1.7 MB
   Load Address: 00008000
   Entry Point:  00008000
   Verifying Checksum ... Bad Data CRC


The script I'm using to make my kernel image is:

SRC=$2/arch/arm/boot/uImage
    if [ -f $SRC ]; then
        printf "Kernel source in: %s\n" $SRC 
    else    
        printf "Error: No kernel source in : %s\n" $SRC
     exit 0
    fi
    mkimage -T kernel -C none -a 0x8000 -e 0x8000 -d $SRC scp_uimage

The above script is called with:

    echo "Destination: scp_zimage"create_flash_image kernel linux-2.6.24/

What do I need to do differently with mkimage so that u boot is happy with the CRC?
