I HIGHLY recommend that you do the CRC32 stuff mentioned on these pages:
http://docswiki.gumstix.org/U-Boot
http://docswiki.gumstix.org/Calculating_32_bit_CRCs

Also, for the cp.b command, you can use:

cp.b a2000000 0 ${filesize}

The loadb command should automatically set the filesize variable. You
can double check by using:

echo ${filesize}

Once you've got the new u-boot working, you can just drop into u-boot
and do a saveenv to get the environment variables set.
