Beyond its kernel, Zephyr includes all the necessary components and libraries required to develop a full application such as device drivers, protocol stacks, filesystems and firmware update [3]. HistoryIn November 2015, it was originally developed as Rocket[4][5][6] kernel by Wind River Systems for Internet of things (IoT) devices.[7] In February 2016, Zephyr became a project of the Linux Foundation.[8][9] Since then, early members and supporters of Zephyr include Intel, NXP Semiconductors, Synopsys, Linaro[10], Texas Instruments, DeviceTone, Nordic Semiconductor and Oticon.[11] FeaturesZephyr intends to provide all necessary components to develop resource-constrained and embedded or microcontroller-based applications. This includes but is not limited to[12]:
Configuration and Build systemZephyr 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]. KernelThe kernel offers several features that distinguish it from other small OSes[15]:
SecurityA group is dedicated to maintaining and improving the security.[16] Also being owned and supported by a community means the eyes of the world's open source developers are vetting the code, which significantly increases Zephyr security.[8] See also
