ARM-PRos Operating System

A minimalistic 64-bit operating system written in C and Assembly for ARMv8-A architecture

Overview

ARM-PRos is my experimental operating system project for the ARMv8-A architecture. It's practically bare bones right now, but if I find the strength to develop this project further, I'll try to turn it into something more.

Roadmap

• UART Driver: Basic text output (puts, puthex, putc)
• UART Input
• String Library (strcmp, strlen, atoi)
• Kernel Shell
• Framebuffer
• Interrupt Controller (GIC)
• Keyboard Driver
• Timer Driver
• Physical Memory Manager
• PCI Scanning
• FAT32 file system
• *.ELF programs
• Multitasking

Building from Source

Install aarch64-linux-gnu-gcc (or clang if you wanna use dcr) compiler using your package manager, then run build script:

chmod +x build-linux.sh
./build-linux.sh

Or use dcr

dcr build

Runing ARM-PRos

Install qemu-system-aarch64 emulator then run this command:

./run-linux.sh

Or manually:

qemu-system-aarch64 \
    -M raspi3b \
    -drive file="$SD_IMG",format=raw,if=sd,index=0 \
    -kernel "$KERNEL_IMG" \
    -serial stdio \
    -display gtk

Or use dcr

dcr run
