Future proof

As a leader in the Zephyr community, TI is committed to the evolution of embedded innovation. TI’s deep collaboration with Zephyr ensures that the open-source RTOS evolves in lockstep with your hardware needs, providing a stable, high-growth foundation for all your applications.

Develop with confidence.

Leverage the flexibility of open-source software backed by TI’s broad embedded portfolio and long-term product availability. Through our Platinum-level membership in the Zephyr Foundation, you benefit from TI's leadership in both upstream and downstream collaboration, ensuring your ecosystem remains stable, supported, and ready for production.

Upstream collaboration

Official Zephyr repository

Stay synchronized with the latest Zephyr updates. This repository offers a stable implementation that aligns with community standards, ensuring your development remains reliable while leveraging fast access to cutting-edge innovation. 

  • Access leading-edge community innovation
  • Leverage fully open-source collaboration
  • Benefit from TI upstream contributions

Downstream collaboration

TI validated Zephyr repository

Move from prototype to production faster. Our downstream repositories are forked from the official Zephyr repository, providing you with pre-validated software and early access to the latest TI board features before they are merged into the upstream repository.

  • Reduce time-to-market with pre-validated packages
  • Simplify integration with user-specific examples
  • Get early access to the latest TI hardware features

Quality, validation & product readiness

Built for production, not just prototypes

Successful products require more than just software availability—they demand rigorous quality, predictable release cycles, and long-term maintainability.

TI enhances your Zephyr software quality through continuous validation on real hardware, simplifying your development workflow and streamlining your path to compliance.

Simplify your qualification process

Reduce your testing burden with TI’s production-grade CI/CD pipeline. Every SDK release includes a full Twister suite with HIL (Hardware-in-the-loop) validation on real ASM, MSP, and SimpleLink boards, ensuring your software is battle-tested on actual hardware.

Streamline your own certification by using our downloadable test reports. Available in JSON, XML, and HTML formats, these reports allow you to directly cite validated results in your own qualification packages.

Automated testing for total accuracy

Eliminate manual error with Twister, Zephyr’s official integrated test runner. Twister automates your entire workflow, building and executing tests across both emulators and real hardware to ensure consistent, repeatable performance.

Gain deep visibility into your design with automated tracking of pass/fail results and memory footprints. Integrate Twister results seamlessly into your automated CI/CD pipelines or use them for rapid, data-driven manual review.
Open-source RTOS is changing how embedded software is developed. At TI, we are embracing this shift by contributing upstream and collaborating with the Zephyr community, pairing our industry-leading silicon with the Zephyr RTOS as a first-class platform to create a unified, scalable ecosystem. This partnership removes low-level development complexity, allowing developers to focus on what truly matters: bringing innovative ideas to market faster.
