This repository is a fork of the mbed DAPLink firmware repository adding experimental WebUSB support.

New features

USB DFU

The firmware has an additional USB Device Firmware Upgrade interface that can be used to flash the target microcontroller instead of the mass-storage drag'n'drop interface.

WebUSB

The firmware reports descriptors for WebUSB support, allowing WebUSB-enabled pages to access the device. Currently, the only interface accessible is the new USB DFU interface, which can be used to reprogram the target directly from the browser.

In the future, CMSIS-DAP commands could be proxied through another USB interface to allow direct SWD debug access from the browser.

Supported Hardware

The primary development platform is the ST Nucleo F103RB development board. The DAPLink firmware has been ported to run on the embedded STLink/V2-1 present on all ST Nucleo boards.

See Installing Firmware for flashing instructions.

Demos

webdfu-util

https://devanlai.github.io/webdfu/dfu-util/

A utility similar to dfu-util, but contained entirely in the browser.

mbed-download

https://devanlai.github.io/webdfu/mbed-download/

A proof-of-concept that uses the mbed remote compile API to build mbed programs and flash them with a single button press.
