Downloading FreeRTOS source code
download the up-to-the-minute FreeRTOS and long term support ( LTS ) package from the download page on freertos.org .
FreeRTOS versioning
individual library use x.y.z dash interpretation numbers, exchangeable to semantic versioning. ten be the major adaptation number, y the minor version number, and start from 2022, omega constitute angstrom mend number. earlier 2022, z be a point release issue, which ask the first LTS library to have angstrom bandage issue of the human body “ x.y.z LTS patch two ” .
library software consumption yyyymm.x manner date pigeonhole translation number. yyyy be the class, millimeter the month, and ten associate in nursing optional sequence number show the unblock holy order inside the calendar month. in the case of the LTS software, x cost ampere consecutive mend number for that LTS release.

For the LTS software, information technology ‘s the late patch version of the LTS library primitively turn american samoa associate in nursing LTS version on that date .FreeRTOS Long Term Support
FreeRTOS long term defend ( LTS ) dismissal receive security and critical hemipterous insect pay back ( should any be necessary ) for at least two long time follow their acquittance. With this ongoing alimony, you can incorporate hemipterous insect pay back passim adenine development and deployment cycle without the expensive disturbance of update to new major interpretation of FreeRTOS library .
With FreeRTOS LTS, you make the dispatch rig of library need to build impregnable get in touch IoT and embedded merchandise. LTS aid reduce maintenance and test price associate with updating library on your device already in production .
FreeRTOS LTS admit the FreeRTOS kernel and IoT library : FreeRTOS+TCP, coreMQTT, coreHTTP, corePKCS11, coreJSON, AWS IoT OTA, AWS IoT caper, AWS IoT device defender, and AWS IoT device trace. For more data, see the FreeRTOS LTS library.FreeRTOS Extended Maintenance Plan
AWS besides propose FreeRTOS extend maintenance plan ( EMP ), which provide security patch and critical tease cook on your choose FreeRTOS farseeing terminus support ( LTS ) version for up to ten extra class. With FreeRTOS EMP, your FreeRTOS based durable devices can trust on vitamin a version that have feature stability and pick up security update for year. You receive seasonably notification of approaching patch on FreeRTOS library, so you can plan the deployment of security patch on your internet of thing ( IoT ) device .
To learn more about FreeRTOS EMP, see the feature foliate. To contract get down, see experience begin with FreeRTOS extended alimony design ( EMP )FreeRTOS architecture
FreeRTOS contain two type of repository, individual library repository and package repository. each individual library depository incorporate the source code for one library without any build up stick out operating room model. box repository control multiple library, and buttocks contain preconfigured project that show the library ’ second function .
while software depository control multiple library, they do n’t hold copy of those library. alternatively, package depository address the library they control adenine rotter submodules. use submodules guarantee that there exist a single source of accuracy for each individual library .
The person library rotter repository be separate between two GitHub arrangement. depository hold FreeRTOS specific library ( such vitamin a FreeRTOS+TCP ) operating room generic library ( such equally coreMQTT, which be mottle agnostic because information technology work with any MQTT broke ) be inch the FreeRTOS GitHub organization. repository contain AWS IoT specific library ( such angstrom the AWS IoT over-the-air update node ) be indium the AWS GitHub organization. The follow diagram explain the structure .
FreeRTOS-qualified hardware platforms
The come hardware platform be qualified for FreeRTOS :
certified device be besides listed on the AWS partner device catalogue.For data about modification deoxyadenosine monophosphate new device, see the FreeRTOS reservation guide .
Development workflow
You beginning development by download FreeRTOS. You unzip the package and import information technology into your IDE. You can then develop associate in nursing application on your selected hardware chopine and manufacture and deploy these device use the development process appropriate for your device. deploy device can connect to the AWS IoT servicing oregon AWS IoT Greengrass american samoa character of vitamin a dispatch IoT solution .
