I will email you the boot.bin and dfu-utils.tar.gz, you have to use this
version for it to work

If you expand the dfu-utils.tar.gz in ~/beagle, you should be able to
do:

sudo ~/beagle/dfu-util/src/dfu-util -v --alt 0 -D ~/beagle/uImage

  I added this to my env var's in u-boot:

set dfu 'run setneteth bootargs_base bootargs_nfs; bootm'

  Got a chance to try the DFU:
