The Texas Instruments Zephyr GitHub repository is the starting point for Zephyr development on supported Texas Instruments devices. TI's Zephyr solution is based on the Zephyr project and utilizes the same familiar environment, tools, and dependencies.
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.
This release of TI Zephyr is based on v3.6.0 and includes support for the following Texas Instruments boards and devices. This release specifically adds support for CC2340R5 and the LP_EM_CC2340R5 Launchpad.
- CC1352P
- CC1352R
- CC2652P
- CC2652R
- CC1352P7
- CC1352R7
- CC2652P7
- CC2652R7
- CC3220SF
- CC3235SF
- CC2340R5
- cc1352p1_launchxl
- cc1352p7_launchpad
- cc1352r1_launchxl
- cc26x2r1_launchxl
- cc3220sf_launchxl
- cc3235sf_launchxl
- lp_em_cc2340r5
For getting started, please refer to the Upstream Zephyr Readme for the Zephyr project and follow the same getting-started guide for setting up the environment and building your first application.
NOTE: When running
west initin the getting-started guide it's important to instead runwest init -m https://github.com/TexasInstruments/simplelink-zephyr -mr v3.6.0-d0ae1a8b105-ti-8.20.00_ea zephyrprojectin order to use the TI Zephyr repository.
Currently the XDS110 debugger supplied with TI Launchpads is not natively
supported in the west Zephyr tool for all devices. In order to flash/debug the
CC2340R5 device with west, only JLink
is available. The recommended version to use is V7.94f which has been used for
validation. Note that it is also possible to build an application in Zephyr
targeting CC2340R5, and to use Code Composer Studio
to both flash and debug the application using the XDS110 debugger.
TI will tag each release with the following format: {upstream-tag}-ti-M.mm.pp(_optional-qualifier)
This tag can be broken down into 4 components:
- upstream-tag: This is the tag or commit of the Zephyr repo that the TI release is based on
- -ti-: Separator
- TI release version: This is TI's version on top of the upstream Zephyr version. The version scheme is explained below.
- Qualifier. The qualifier keyword is described below.
The TI version follows a version format, M.mm.pp, where:
- M is a 1 digit major number,
- mm is a 2 digit minor number,
- pp is a 2 digit patch number.
M.mm will follow TI's SimpleLink SDK version and is an indicator that the TI added content is based on the SimpleLink SDK with matching M.mm.
Tags that are appended with _ea are for demo only and are beta quality, while tags without the _ea keyword should be treated as production worthy releases.
All releases will be tagged using the version format above. Release notes are provided in the form of GitHub's release notices. Read the release notes for your selected version here:

This release is provided as-is and should be considered Beta quality. This product is meant for demonstration purposes only.
