Zephyr is a small real-time operating system[3] for connected, resource-constrained and embedded devices (with an emphasis on microcontrollers) supporting multiple architectures and released under the Apache License 2.0. Beyond its kernel, Zephyr includes all the components and libraries needed to develop a full application such as device drivers, protocol stacks, file systems, and firmware updates.[4]
History[edit]
In November 2015, it was originally developed as Rocket[5][6][7] kernel by Wind River Systems for Internet of things (IoT) devices.[8]
In February 2016, Zephyr became a project of the Linux Foundation.[9][1] Freedom download windows.
Since then, early members and supporters of Zephyr include Intel, NXP Semiconductors, Synopsys, Linaro,[10]Texas Instruments, DeviceTone, Nordic Semiconductor, Oticon, and Bose.[11]
Features[edit]
Zephyr intends to provide all components needed to develop resource-constrained and embedded or microcontroller-based applications. This includes, but is not limited to:[12]
- A small kernel
- A flexible configuration and build system for compile-time definition of required resources and modules
- A set of protocol stacks (IPv4 and IPv6, OMA LWM2M, MQTT, 802.15.4, Bluetooth Low Energy, CAN)
- A virtual file system interface with several flash file systems for non-volatile storage
- Management and device firmware update mechanisms
Configuration and build system[edit]
Zephyr uses Kconfig and device tree as its configuration systems, inherited from the Linux kernel but implemented in Python for portability to non-Unix operating systems.[13] The RTOS build system is based on CMake, which allows Zephyr applications to be built on Linux, macOS and Microsoft Windows.[14]
Kernel[edit]
The kernel offers several features that distinguish it from other small OSes:[15]
- Multiple scheduling algorithms
- Highly configurable and modular for flexibility, with resources defined at compile-time
- Memory protection unit (MPU) based protection
- Asymmetric multiprocessing (AMP, based on OpenAMP) and symmetric multiprocessing (SMP) support
Security[edit]
A group is dedicated to maintaining and improving the security.[16] Also, being owned and supported by a community means the world's open source developers are vetting the code, which significantly increases security.[9]
