1. Release information

This article aims to describe the content of the software release included in the STM32CubeMP1 Package, version v1.4.0

2. Delivery scope and purpose

The STM32CubeMP1 Package is a software package running on Arm^® Cortex^®-M4 processors and is a fundamental part of the STM32MPU 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^TM and OpenAMP.
• All embedded software utilities delivered with a full set of examples.

It also includes:

• BSP for the STM32MP157x-EV1 Evaluation board and the STM32MP157x-DK2 Discovery kit (button and LEDs only)
• Multi-core components

• OpenAMP
• ResourceManager
• CoproSync

• Projects : several projects ( examples, applications and demonstration firmware) are implemented in different IDEs:

• STM32CubeIDE : IDE delivered by ST

• All the STM32MP157C-DK2 and STM32MP157C-EV1 projects are available on STM32CubeIDE.

• EWARM (version 8.32.3 and laters)

• Most of the STM32MP157C-DK2 projects are ported on EWARM.

• MDK-ARM (Pack Keil^®.STM32MP1xx_DFP.1.1.0.pack + MDK-ARM 5.27 and laters)

• Most of the STM32MP157C-DK2 projects are ported on MDK-ARM.

• System Workbench for STM32 toolchain (SW4STM32): now deprecated

• This IDE is no longer supported by STMicroelectronics, the reference is now STM32CubeIDE
• All the projects are still available on SW4STM32 but these projects are to be imported to the STM32CubeIDE.

3. Supported devices

The drivers provided within this package support all STM32MP15x line devices.
More details are provided in the article STM32MP15 ecosystem release note - Boards chapter.
