What is the exact command (and options) to use dfu-util to upgrade the Pyboard-D firmware. I am confident about getting the Pyboard-D into (and out of!) dfu mode, but I want to be absolutely certain about the command I need to use to upload the firmware.

e.g. sudo dfu-util --alt 0 -D PYBD_SF2_W4F2.dfu
File name to be changed for the various models

Thanks, worked perfectly
