<title>Device Firmware Update</title>
<para>The Device Firmware Update (DFU) part of the firmware will be
booted first, it is checking if a button is active or if the software
reset reason was for DFU and then activates the DFU part or jumps to
the main application. DFU can be activated at any time using
<command>dfu-util</command> on the USB Host.</para>
<para>The <command>dfu-util</command> application might be already
packaged for your distribution, the source code can be found on the
<ulink url="http://dfu-util.gnumonks.org/">dfu-util.gnumonks.org</ulink>
website. To update the main part of the firmware simply do:
<screen>
$ $ dfu-util -d 16c0:0762 -a0 -D ./main_simtrace.bin -R
