This article aims to describe the content of the software release included in the STM32CubeMP2 Package, version v.1.1.0, which is part of the STM32 MPU ecosystem release note - v6.0.0.
1. Delivery purpose and scope[edit | edit source]
The STM32CubeMP2 Package is a software package running on 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.
It also includes:
- BSP for the STM32MP257F-EV1 Evaluation board
, STM32MP257F-DK Discovery kit , and STM32MP257F-DK Discovery kit for STM32MP23x lines evaluation 
(LED, button, STPMIC25 and COM ports) - Multi-core components
- OpenAMP
- ResourceManager
- Projects: several projects (examples, applications) are implemented in IDE delivered by ST
- STM32CubeIDE delivered by ST
- All the STM32MP257F-EV1 , STM32MP257F-DK , STM32MP257F-DK for STM32MP23x lines evaluation projects are available on STM32CubeIDE.
- All the STM32MP257F-EV1
- BSP for the STM32MP257F-EV1 Evaluation board

6.2. Main restrictions[edit | edit source]
- A compilation issue is observed when we develop a project using I3C LL API and any other internal peripheral using HAL API.
- There is a fix available on Github, to take on top of the Yocto-based Linux embedded software, for this compilation issue: Fix to the I3C compilation in hybrid HAL/LL usage
- There is python package issue observed when using the script to sign the firmware.
- This issue is resolved by using following solution available on github (to take on top of the Yocto-based Linux embedded software) : Fix python package issue in signing script
