<h1>dfu-util - Device Firmware Upgrade Utilities</h1>
<h2>Description</h2>
<p>
dfu-util is a host side implementation of the <a
href="http://www.usb.org/developers/devclass_docs/usbdfu10.pdf"
title="DFU revision 1.0"> DFU 1.0</a> and <a
href="http://www.usb.org/developers/devclass_docs/DFU_1.1.pdf"
title="DFU revision 1.1">DFU 1.1</a> specifications of the USB forum.
DFU is intended to download and upload firmware to/from devices connected
over USB. It ranges from small devices like micro-controller boards
to mobile phones. Using dfu-util you can download firmware to your
DFU-enabled device or upload firmware from it. dfu-util has been
tested with the Openmoko Neo1973 and Freerunner and many other devices.

<h2>Releases</h2>
<p>
Releases of the dfu-util software can be found in the <a
href="http://dfu-util.gnumonks.org/releases/" title="Releases">
releases</a> folder.
The current release is 0.7.
</p>
<p>
We offer binaries for Microsoft Windows and some other platforms.
dfu-util uses libusb 1.0 to access your device, so
on Windows you have to register the device with the WinUSB driver
(alternatively libusb-win32 or libusbK if libusbx 1.0.13 or later),
please see the <a
href="https://github.com/libusbx/libusbx/wiki/Windows-Backend">libusbx wiki</a>
for more details.
</p>
<p>
Mac OS X users can also get dfu-util from <a href="http://brew.sh/">Homebrew</a> with "brew install dfu-util" or from <a href="http://www.macports.org/">MacPorts</a>.
</p>
<p>
Most Linux distributions ship dfu-util in binary packages for those
who do not want to compile dfu-util from source.
On Debian, Ubuntu, Fedora and Gentoo you can install it through the
normal software package tools. For other distributions
(namely OpenSuSe, Mandriva, and CentOS) Holger Freyther was kind enough to
provide binary packages through the <a
href="https://build.opensuse.org/package/show?package=dfu-util&project=home%3Azecke23">Open Build Service</a>.
</p>
