Extended Maintenance Plan


The FreeRTOS Extended Maintenance Plan (EMP) allows you to receive security patches and critical bug fixes on your chosen FreeRTOS Long Term Support (LTS) version for up to 10 years* beyond the expiry of the initial LTS period. Provided by Amazon Web Services (AWS), FreeRTOS EMP can help you keep your microcontroller-based devices secure for years, save operating system upgrade costs, and reduce risks associated with patching your devices in the field.


Reduce product liability risks

Run firmware that receives security patches on a feature-stable codebase throughout the lifecycle of your product. A feature-stable codebase ensures that you receive security patches on the same LTS version, so you don't need to upgrade to the latest FreeRTOS version with potentially breaking changes.

Save operating system upgrade costs

Continue to use FreeRTOS libraries that provide feature and API stability for the term of your subscription, so you don't need to incur development, testing, and QA costs to migrate to the latest FreeRTOS release.

Improve device security for the long term

Receive security patches and critical bug fixes on your chosen FreeRTOS LTS libraries to improve security of your IoT devices throughout their lifecycle.

Reduce the risk of delayed updates

Updating devices with critical fixes involves project planning, release readiness testing, and over-the-air (OTA) update scheduling. Reduce delayed deployment risks by receiving timely notification of upcoming patches, and needed support with integration issues.

How it works

FreeRTOS EMP extends the maintenance period of FreeRTOS LTS libraries from the initial two years to up to an additional ten years. Once you choose an LTS version, you will be provided with a private git repository that contains your chosen LTS version and any patches (if any are required). Like the FreeRTOS LTS libraries, FreeRTOS EMP libraries will continue to have feature and API stability for the duration of your subscription.

* AWS may terminate the Extended Maintenance Plan for any version of LTS before the expiration of your subscription term as permitted under the agreement governing your use of AWS services, including upon at least 12 months' notice.
