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:
shell
$ 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 cargo run.
Place the following in .cargo/config.toml to use nrfdfu as the Cargo runner:
toml
[target.'cfg(all(target_arch = "arm", target_os = "none"))']
runner = "nrfdfu"
