Building an Operating System In Rust Part 2

Short summary

Part 2 of a hands-on series on building an operating system in Rust, focusing on the kernel entry point. The author explains core low-level concepts—registers, stack, stack pointer, instruction set, and program counter—then transitions to writing assembly boot code because Rust requires a pre-configured stack pointer. The tutorial targets Aarch64 architecture and includes a GitHub repo for following along.

• •Explains CPU fundamentals: registers, stack, instruction set, and program counter for Aarch64
• •Demonstrates why assembly is required for kernel boot code since Rust expects a stack pointer to already exist
• •Provides a GitHub repo to clone and follow along with the OS-building tutorial
