About Simple implementation of an OS for the BeagleBoard C4 with ARMv7 A8 processor.
MinionOS is a simple operating system implementation designed for the BeagleBoard C4 single-board computer, which features an ARMv7 Cortex A8 processor (OMAP 3530). Developed as an educational and experimental project, it provides a hands-on demonstration of core OS concepts including GPIO control, interrupt handling, system timers, system calls, a filesystem, scheduler, virtual memory, process management, inter-process communication (IPC), and basic user applications. The project also includes a shell, low-level drivers for MMC/SD, SPI, UART, and high-level DMX support. Written primarily in C with Assembly components, it uses Code Composer Studio v7 as a design tool. The repository is licensed under MIT.
Key Features
Pros & Cons
- Covers a wide range of OS fundamentals from GPIO to virtual memory and IPC
- Open-source (MIT license) and free to use
- Modular design with separate components for drivers, system calls, and scheduler
- Well-documented in the repository with a clear README and code comments
- Limited to the BeagleBoard C4 with OMAP 3530 processor, not portable to other boards without modification
- Primarily educational; not intended for production or real-world deployment
- No pre-built binaries or releases; requires building from source
