This article introduces the structure and the content of the STM32CubeMP2 Package, the embedded software part of STM32Cube™, running on the Arm® Cortex®-M33 coprocessor. It references also other interesting wiki articles to better understand and use the STM32CubeMP2 Package.

1. What is the STM32CubeMP2 Package[edit source]

STM32CubeMP2 Package, running on the Arm® Cortex®-M33 processor, consists of:

  • The hardware abstraction layer (HAL), enabling portability between different STM32 devices via standardized API calls
  • The low-layer API (LL), a light-weight, optimized, expert oriented set of APIs designed for runtime efficiency and so enhanced performance
  • The board support package drivers (BSP), based on HAL drivers, an API set for the evaluation board and third-party components.
  • A collection of middleware components (such as FreeRTOS)
  • A collection of examples, running on an MPU board and allowing demonstration of a basic implementation of features from a set of IPs

STM32CubeMP2 Package uses components such as OpenAMP and ResourceManager that allow easy communication and resource sharing between main processors running with Linux on Arm® Cortex®-A35, and MCU coprocessors running on Arm® Cortex®-M33.

  • OpenAMP is a library implementing the remote processor service framework (RPMsg) which is a virtio-based messaging bus that allows a local processor to communicate with remote processors available on the system.
  • ResourceManager is a utility that handles peripheral-accessibility requests and system-resource configuration.

2. Software architecture overview[edit source]

Software architecture overview is described in STM32CubeMP2 Package architecture.

3. STM32CubeMP2 Package structure[edit source]

This chapter describes the structure of the STM32CubeMP2 Package (drivers, middleware components...).

STM32CubeMP2 Package offers a highly portable Hardware Abstraction Layer (HAL), built around a generic and modular architecture.

This HAL allows the upper layers, middleware and application, to implement functions whenever STM32MP25 device is used. This improves the library code re-usability and guarantees easy portability from one device to another. STM32CubeMP2 Package also offers a highly portable Low Layer interface (LL), which allows a quick, simple and optimized API to access the STM32MP2 registers.

The STM32CubeMP2 Package is provided with the structure shown below.
