nRF DFU Flashing Tool
nrfdfu-rs is an implementation of the protocol used by the bootloader on the nRF family of microcontrollers.
It can be used to flash an ELF firmware file onto devices such as the nRF52840 Dongle.
This tool was written to replace
pc-nrfutil in our trainings, so it implements a subset of the features found there.
Run the following command to install the
nrfdfu executable on your system:
$ cargo install nrfdfu
The tool is designed to be passed an ELF file as follows:
$ nrfdfu path/to/firmware.elf
This allows using it as a Cargo runner to automatically flash your Rust firmware during
Place the following in
.cargo/config.toml to use
nrfdfu as the Cargo runner:
[target.'cfg(all(target_arch = "arm", target_os = "none"))'] runner = "nrfdfu"
