fatload? FATLOAD??? You mean you have a FAT filesystem on that partition???
Than why do you try using usbboot? usbboot like diskboot try to load
an U-Boot image from a RAW partition, i. e. without any filesystem on

If you have a FAT filesystem you should use fatload to load your image.
If you have an ext2 filesystem you should use ext2load to load your image.
If you have a foo filesystem you should use fooload to load your image.

You used the command without having a valid image IN THE RAW PARTITION.
The "First Block: 1, # of blocks: 10239, Block Size: 512" message
should not be printed at all; it is actually debug code only. I'll
change this in the code. I'll also make the code verify the header
checksum - just relying on the magic number is probably a bit too
