FreeRTOS Porting

What is FreeRTOS

Developed in partnership with the world's leading chip companies over a 20-year period, and now downloaded every 170 seconds, FreeRTOS is a market-leading real-time operating system (RTOS) for microcontrollers and small microprocessors. Distributed freely under the MIT open source license, FreeRTOS includes a kernel and a growing set of libraries suitable for use across all industry sectors. FreeRTOS is built with an emphasis on reliability and ease of use. FreeRTOS includes libraries for connectivity, security, and over-the-air (OTA) updates, and demo applications that demonstrate FreeRTOS features on qualified boards.

Porting FAQs

What is a FreeRTOS port?

A FreeRTOS port is a board-specific implementation of APIs for the required FreeRTOS libraries and the FreeRTOS kernel that your platform supports. The port enables the APIs to work on the board, and implements the required integration with the device drivers and BSPs that are provided by the platform vendor. Your port should also include any configuration adjustments (e.g. clock rate, stack size, heap size) that are required by the board.

If you have questions about porting that are not answered on this page or in the rest of the FreeRTOS Porting Guide, please see the available FreeRTOS support options.
