NateOS – A Simple, Modular AArch64 Operating System

Overview

NateOS is an open-source operating system designed to run on the Raspberry Pi models. It is built from scratch using C and Assembly language, focusing on simplicity, modularity, and ease of use.

Features

• Simple, modular design for easy maintenance and extension
• Support for AArch64 architecture
• Basic kernel services:
  • Serial console output
  • Basic Display output
• User-space library for device drivers and system calls

Getting Started

Prerequisites:
A Raspberry Pi.

Build NateOS:
Clone the repository and run make in the project directory to build the kernel image (kernel8.img) and user-space libraries.

Install NateOS on your Raspberry Pi: Not Yet Tested

Test NateOS:
Once booted, you should see a serial console prompt on the screen. You can interact with the operating system by typing commands.

Known Issues and Limitations

• Very Limited rendering
• Limited device driver support (UART only)
• No network stack implemented
• Debugging tools are minimal
