### USB DFU Utility
http://dfu-util.gnumonks.org/
## Usage Notes
DFU boot downloads to RAM then executes. Need a DFU suffix, but also a header
> cp blinky.bin blinky.dfu
Add DFU suffix and address prefix:
> /usr/local/bin/dfu-suffix --pid=0x000c --vid=0x1fc9 --did=0x0 -s 0 -a blinky.dfu
Create header:
> echo "0000000: da ff 02 00 ff ff ff ff" | xxd -g1 -r > header.bin
where the 02 means 2 x 512 + 16 bytes ... this should be automated.
Assume rounded up.
Add header
> cat header.bin blinky.dfu > load.dfu
Check for device:
> /usr/local/bin/dfu-util -l
Download (I used the latest dfu-util from git)
> /usr/local/bin/dfu-util -d 1fc9:000c -a 0 -D load.dfu
