The Zephyr Project is a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource constrained devices, and built with security in mind.
The Zephyr OS is based on a small-footprint kernel designed for use on resource-constrained systems: from simple embedded environmental sensors and LED wearables to sophisticated smart watches and IoT wireless gateways.
The Zephyr kernel supports multiple architectures, including ARM (Cortex-A, Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, SPARC, MIPS, and a large number of supported boards.
Welcome to Zephyr! See the Introduction to Zephyr for a high-level overview, and the documentation's Getting Started Guide to start developing.
Besides this repository (tl_zephyr), the SDK pulls in the following Telink
maintained modules through its west manifests (west.yml and
submanifests/telink.yaml). Forked repositories carry Telink-specific
modifications and optimizations on top of upstream projects; others are Telink
provided components. All forked modules are published under the tl_ prefix
to distinguish them from their upstreams:
- tl_xz — fork of XZ Utils integrated as a Zephyr module
- tl_openthread_libs — Telink-provided prebuilt OpenThread FTD libraries
- hal_telink — Telink HAL module (follows the upstream
hal_<vendor>naming convention)
For details on each module, see the linked repositories.
The modules above were previously published under their upstream-derived names
(zephyr, xz and openthread_telink_lib)
and have been renamed with the tl_ prefix to make the Telink maintained
components of the SDK easy to identify.
