184.108.40.206. USB Device Firmware Upgrade (DFU)¶
When working with USB Device Firmware Upgrade (DFU), regardless of the medium to be written to and of the board being used, there are some general things to keep in mind. First of all, you will need to get a copy of the dfu-util program installed on your host. If your distribution does not provide this package you will need to build it from source. Second, the examples that follow assume a single board is plugged into the host PC. If you have more than one device plugged in you will need to use the options that dfu-util provides for specifying a single device to work with. Finally, to program via DFU for a given storage device see the section for the storage device you are working with.
