Rust Raspi3 OS Tutorials
This project is a tutorial and framework for building a low-level, bare-metal operating system from scratch using the Rust language. It focuses on ARMv8 kernel development specifically for the Raspberry Pi 3, providing the resources necessary to implement a monolithic kernel that runs directly on hardware without an underlying operating system.
The project distinguishes itself by providing a complete embedded cross-compilation suite within a containerized environment to ensure consistent builds. It includes a dedicated kernel deployer that uses a serial interface and chainloader to load and boot kernel images onto physical hardware via UART.
The framework covers core system capabilities including virtual memory mapping and configuration for resource isolation, hardware exception handling for system stability, and the implementation of serial drivers for console output. It also supports hardware simulation through emulators and on-chip debugging to verify kernel logic before physical deployment.
