Introduction

• PyDFUUtil provides for easy access to the devices that supports DFU interface over host machine's Universal Serial Bus (USB) system for Python 3.
• PyDFUUtil is an open realisation of original dfu-util and thin wrapper over libusb (uses PyUsb library as a backend).

[!WARNING] The current status of the project is BETA version. Use it for your own risk

[!IMPORTANT] Current version implements but not tested with real dfuse devices!

[!TIP] Searching for contributors for testing the library

Requirements and platform support

• Since PyDFUUtil uses the libusb library it has similar dependencies for using libusb
• PyDFUUtil primarily tested on Linux and Windows, but also can work on each platform where PyUsb library are available, including MacOS

Installing

PyDFUUtil is generally installed through pip

# the latest official release
python -m pip install pydfuutil

# install a specific version (e.g. 0.0.1b1)
python -m pip install pydfuutil==0.0.1b1

Usage

pydfuutil

pydfuutil -h 
# or
python -m pydfuutil -h

About

Dfu-util - Device Firmware Upgrade Utilities

Dfu-util is the host side implementation of the DFU 1.0 and DFU 1.1 specification of the USB forum.

DFU is intended to download and upload firmware to devices connected over USB. It ranges from small devices like micro-controller boards up to mobile phones. With dfu-util you are able to download firmware to your device or upload firmware from it.

dfu-util has been tested with Openmoko Neo1973 and Freerunner and many other devices.

Footnotes

• On systems that still default to Python 2, replace python with python3
• Project is in develop, it fulls issues not according to original dfu-util!
