• The ESP-IDF v4.4.x release requires an updated toolchain (xtensa-esp32xx-elf-gcc esp-2021r2-patch3-8.4.0) and is not compatible with the older toolchain used in Amazon FreeRTOS (xtensa-esp32xx-elf-gcc esp-2020r3-8.4.0).

Hello, @aggarg and @paulbartell!

This pull request updates ESP-IDF shipped with AFR to v4.4.2 and also adds support for the ESP32-S3 SoC.

As mentioned, the FreeRTOS-Kernel submodule for this PR is based on the latest main branch commit - https://github.com/FreeRTOS/FreeRTOS-Kernel/commit/195a351ec797ba434c0e00fbba1d1f6adb74e279. The same for AFR main branch is set at v10.4.3 LTS Patch 2 and there is a draft PR for updating it - https://github.com/aws/amazon-freertos/pull/3507.

Will we have to wait till the above draft PR is merged? Is there a plan to use only LTS versions of the FreeRTOS kernel in the AFR main branch henceforth?

The iot-reference integration for the ESP32S2 can be found as part of this repo: https://github.com/FreeRTOS/iot-reference-esp32c3 This repo uses IDF 4.4 so it has support for all ESP32 devices.
