OneWo-zepLinux
The OneWo-zepLinux system, based on a deeply customized Zephyr RTOS, pioneers an MCU-level Linux API compatibility layer. This allows Linux ecosystem applications to run stably on resource-constrained microcontroller (MCU) platforms without re-engineering, filling the technical gap in the embedded domain for "lightweight real-time + Linux ecosystem compatibility." Currently, the core code of zepLinux is open-sourced on GitHub, available for download and community collaboration for industrial control, IoT, smart terminals, edge embedded, and other scenarios.
[Technical Breakthrough: Zephyr Kernel + Linux Compatibility, Reshaping the MCU Development Paradigm]
zepLinux is built on the Zephyr RTOS foundation, inheriting its native advantages in lightweight design, real-time performance, multi-architecture support, and modularity, while innovatively constructing a Linux API compatibility subsystem, achieving three core breakthroughs:
- Full-stack Linux API Compatibility: Deep implementation of Linux standard task scheduling, task synchronization, memory management, driver model, and other core subsystems. Linux application code can be directly compiled and deployed to MCUs without large-scale refactoring, significantly reducing cross-platform migration costs.
- MCU-level Ultra-lightweight Design: Retaining Zephyr's microkernel features, with a minimum image size < 45KB, memory footprint < 10KB, and startup time < 5ms, perfectly adapting to mainstream MCUs such as ARM Cortex‑M, RISC‑V, and resource-constrained embedded scenarios.
- Hard Real-time Performance Guarantee: Scheduling latency < 5μs, interrupt response < 2μs, meeting microsecond-level real-time requirements in industrial control, real-time sensing, motion control, etc., balancing the Linux ecosystem with RTOS real-time capabilities.
[Scenario Value: Cost and Efficiency Gains, Accelerating Domestic Production and Intelligence of Embedded Products]
zepLinux addresses three major industry pain points in industrial automation, IoT terminals, automotive MCUs, medical embedded systems, etc.:
- Ecosystem Reuse: Mature Linux ecosystem applications, algorithms, and middleware can be directly migrated to MCUs, avoiding redundant development and shortening product cycles by over 60%.
- Cost Optimization: Running Linux-level applications on MCU hardware replaces traditional "MCU+CPU" dual-chip solutions, reducing hardware costs by 30%–50%.
- Self-control and Autonomy: Self-developed compatibility layer adapts to domestic MCUs and chip platforms, helping to replace key embedded systems with domestically produced alternatives.
