This article aims to describe the content of the software release included in the STM32CubeMP2 package, version v1.3.1, which is part of the Yocto-based_OpenSTLinux ecosystem release note v6.2.1.
1. Delivery purpose and scope[edit | edit source]
The STM32CubeMP2 package is a software package running on the Arm® Cortex®-M33 processor and is a fundamental part of the Yocto-based OpenSTLinux embedded software distribution.
This release includes:
- The STM32Cube HAL: STM32 abstraction layer embedded software ensuring maximized portability across the STM32 portfolio. HAL APIs are available for all peripherals.
- Low-layer APIs (LL APIs): Offering a fast, lightweight, expert-oriented layer that is closer to the hardware than the HAL. LL APIs are only available for a limited set of peripherals.
- A consistent set of middleware components: such as FreeRTOS™ and OpenAMP.
- All embedded software utilities: delivered with a full set of examples.
- Multi-core components
- OpenAMP
- ResourceManager
- SCMIAgent
- All the STM32MP257F-EV1
, STM32MP257F-DK , STM32MP257F-DK for STM32MP23x lines evaluation 
, STM32MP215F-DK Discovery kit projects are available on STM32CubeIDE.

6. Release content[edit | edit source]
This is a maintenance release of the STM32CubeMP2 software package running on Arm® Cortex®-M33 core. The full content is available in STM32CubeMP2 Package content.
6.1. Main changes[edit | edit source]
- Updates for the M33-TD flavor
- Firmware update feature is now available in the StarterApp.
- Low power state management support is enhanced.
- Utility M33TD_NSAppCore is updated to fully support new usecases of Firmware update and Low Power state management.
- A new project VisualWatchdogDemo is added to demonstrate how OSTL running on the Arm® Cortex®-A35 processor can be independently rebooted or recovered from a crash.
- Updates for the A35-TD flavor
- A new example is added which demonstrates full-duplex SPI transfer between two STM32MP257F-EV1 boards using SPI3 and HPDMA3 in Linked-List mode.
- A new application is added which demonstrates how you could use the scmiagent middleware in your Cube Firmware to communicate using ARM SCMI protocol and enable/disable clocks controlled by CA35.
- CMSIS device updates for:
- ETH
- Bugfix: correct malformed comment delimiters and missing opening parenthesis for some definitions.
- PWR HAL: updated to use DSB before WFI in low power functions.
- Bug Fixes and improvements in examples.
