USB DFU Solution


TL-USBDFU is a host-side, cross-platform, customizable software solution that implements firmware upgrade via USB. It works with devices that are compliant to the USB device class specification for Device Firmware Upgrade (DFU) version 1.1. The solution is available for Windows, macOS and Linux.

The overall software architecture is shown right.

The core component is a dynamic link library which provides a cross-platform implementation of the DFU protocol. The library exposes a unified, C-style API which behaves in the same way on all supported platforms. Based on this API custom applications or scripts can be built which work across all platforms. A customizable application with graphical user interface and a command line based utility is included.
