Sounds like a ram problem. Devboard 82 has a 32 bit sdram connection, but
MCM (chip&software) has only 16 bit. Check the sdram_config setting in
kernel configuration, bootloader extracts that from the image to
initialize the processor before uploading the data to be flashed.
It's a bit misleading that the displayed checksum is calculated on the
fly, so it doesn't reveal anything if the image gets corrupted in memory.
