This document provides an overview of the FreeRTOS component, the different FreeRTOS implementations offered by ESP-IDF, and the common aspects across all implementations.

IDF FreeRTOS source code is based on Vanilla FreeRTOS v10.5.1 but contains significant modifications to both kernel behavior and API in order to support dual-core SMP.

This document describes the API and behavioral differences between Vanilla FreeRTOS and ESP-IDF FreeRTOS that were made in order to support Symmetric Multiprocessing (SMP).

官方 FreeRTOS （下文称为原生 FreeRTOS）是一个单核 RTOS。 为了支持各种多核 ESP 目标芯片，ESP-IDF 支持下述不同的 FreeRTOS 实现。

The ESP-IDF FreeRTOS is a modified version of vanilla FreeRTOS which supports symmetric multiprocessing (SMP). ESP-IDF FreeRTOS is based on the Xtensa port of FreeRTOS v10.2.0.

This document provides an overview of the FreeRTOS component, the different FreeRTOS implementations offered by ESP-IDF, and the common aspects across all implementations.

These supplemental features are available on all FreeRTOS implementations supported by ESP-IDF (i.e., ESP-IDF FreeRTOS and Amazon SMP FreeRTOS). This document describes these …
