Toolchain setup

In order to create a device firmware, you will need to set up an embedded toolchain for Rust.

Install rustup

In order to install Rust and Rust components, you will need rustup:

On Unix-like environment, the following command should work just fine:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

There are other ways to install rustup. Check its homepage to learn more.

Install an embedded toolchain

By default, rustup will install a toolchain (compiler, …) for your current host architecture and operating system.

When compiling a device firmware, we need to have a compiler for a different architecture (CPU). The examples used in this workshop contain a rust-toolchain file which will tell rustup to automatically download the toolchain required for your board.

Additional tools

In addition to the actual toolchain, you will need tools to flash the firmware to your device, and to monitor what is going on.

There are a few tools for Rust which can help here. However, we will focus on the probe-run.

You can install probe-run be executing the following command:

cargo install probe-run
