Is ThreadX (Azure RTOS) officially supported on the Cortex-M4 core of STM32MP157F-DK2?

Hello ST Community,

I am currently working with the STM32MP157F-DK2 development kit and exploring RTOS options for the Cortex-M4 core. While FreeRTOS is officially supported through STM32CubeIDE, I would like to know if ThreadX (Azure RTOS)is officially supported and available for use on the Cortex-M4 core of the STM32MP157F-DK2.

Specifically, I am looking for:

• Official support or examples of ThreadX running on the M4 core of this platform

• BSP or middleware integration through STM32CubeMX or STM32CubeIDE

• Any known limitations, configuration notes, or documentation

I understand that ThreadX is well-integrated in STM32H7 and STM32U5 series, but it is unclear whether the same level of support is available for the STM32MP1 series, particularly the M4 core.

If anyone has successfully used ThreadX on the STM32MP157F-DK2 (Cortex-M4), or if ST officially supports this configuration, I would appreciate your insights or pointers to relevant resources.

Thank you in advance.

ST have just switched (back) to FreeRTOS as their "preferred" RTOS:
