Bare Metal Rust: Build Your Own Operating System for Raspberry Pi

💡Bare metal programming allows you to write custom code that runs directly on the hardware without an operating system.

🔧The Raspberry Pi is a versatile board that can be used for learning embedded programming and building custom operating systems.

👨‍💻Rust is a powerful systems programming language that provides memory safety and high-level abstractions, making it ideal for bare metal programming.

🔌You can control the GPIO pins of the Raspberry Pi using the BCM2837 ARM peripheral data sheet, which provides information on the addresses and functions of the pins.

🧰By modifying the linker script and using object copy, you can extract the code from the ELF file and create a flat binary that can be loaded onto the Raspberry Pi.

Do I need an operating system to run code on the Raspberry Pi?

—No, you can run code directly on the hardware using bare metal programming.

Why should I use Rust for bare metal programming?

—Rust provides memory safety and high-level abstractions, making it easier to write bug-free and efficient code for bare metal programming.

How can I control the GPIO pins of the Raspberry Pi?

—You can refer to the BCM2837 ARM peripheral data sheet to find the addresses and functions of the pins and use them to control the GPIO pins.

What tools do I need to build my own operating system for Raspberry Pi?

—You will need Rust, Cargo, the BCM2837 ARM peripheral data sheet, a text editor, and an understanding of bare metal programming concepts.

Can I use other programming languages for bare metal programming?

—Yes, you can use other programming languages like C or assembly language for bare metal programming, but Rust is a popular choice due to its safety features and high-level abstractions.
