Verifying Your Rust Installation for Embedded Development

Main Point

The primary focus of this section in the Rust Embedded Book is to guide users on how to verify their Rust installation, ensuring that they are set up correctly for embedded development.

Key Concepts

• Rust Toolchain: The collection of tools needed for Rust programming, including the Rust compiler (rustc), package manager (cargo), and standard libraries.
• Embedded Targets: Specific configurations tailored for programming embedded systems. These can differ from standard Rust targets for desktop or server applications.

Steps to Verify Installation

1. Check Rust Version:
   • Open your terminal (Command Prompt, PowerShell, or Terminal).
   • This command should return the version of Rust you have installed, confirming the installation.
2. Check Cargo Version:
   • Cargo is the Rust package manager and build system.
   • Similar to rustc, this command should return the version of Cargo.
3. Test Embedded Setup:
   • To ensure that the embedded toolchain is set up, you can check for specific embedded targets.
   • This will list the targets you have installed, including embedded ones like thumbv7em-none-eabihf.

Run the command:

rustup target list --installed

Run the command:

cargo --version

Run the command:

rustc --version

Example Commands

Creating a New Project: After verifying your installation, you can create a new Rust project using:

cargo new my_embedded_project

Install an Embedded Target: If you notice that a specific target is not installed, you can add it using:

rustup target add thumbv7em-none-eabihf

Conclusion

Verifying your Rust installation is a crucial step in getting started with embedded programming. Following the steps outlined above will ensure that your development environment is correctly configured, allowing you to focus on building your embedded applications.
