STM32U5 Classic Core Middleware (CoreMW) MCU Firmware Package

Description

STM32Cube is an STMicroelectronics original initiative to ease developers' life by reducing efforts, time and cost.

Classic CoreMW is a collection of middleware stacks and associated applications allowing RTOS management, File System operations and connectivity through USB and Ethernet. It is based on:

• ST's proprietary stacks: ST USB Device and ST USB Host
• Third parties' stacks: FreeRTOS

This package is exclusively published on GitHub (and is neither available in STM32CubeU5, STM32CubeMX nor STM32CubeIDE available on www.st.com). It contains the integration of the Classic CoreMW stacks with STM32U5 devices, allowing users to get quick access to pre-built projects integrating them.

Note

• The repository containing this package has been created using the git submodule command. Please refer to the "How to use" section explaining how to clone this repository and how to get the latest updates.

List of applications

The STM32U5 Classic CoreMW package contains the following applications:

Note

• Only FreeRTOS_Template application is provided with preconfigured projects for Keil MDK-ARM and STM32CubeIDE toolchains. All others are provided only with preconfigured projects for EWARM toolchain.
• Projects in this package have not been generated with STM32CubeMX (i.e., no .ioc files are delivered).

Boards available

• STM32U5
  • NUCLEO-U575ZI-Q

Development Toolchains and Compilers

• IAR Embedded Workbench for ARM (EWARM) toolchain V8.50.6 + ST-LINK, patch available here
  • This patch supports STM32U575/585 devices
• RealView Microcontroller Development Kit (MDK-ARM) toolchain V5.32 + ST-LINK, patch available here:
  • This patch supports STM32U575/585 devices
• STM32CubeIDE v1.7.0

Dependencies

This package has been developed and tested using the list of components detailed in the table below.

How to use

This repository intrinsically contains the applications (projects and source files) located under folder ./Projects. It also contains the CMSIS Core files under folder ./Drivers/CMSIS/Include for size optimization reason. Other dependencies such as the HAL and BSP drivers, or the middleware libraries themselves are linked using the git submodule command. Please check the instructions below for a proper use.

Note

• USB-PD library is momentarily contained in this repository pending its publication on GitHub. Once published, it will be added as a submodule like the other components.

• To clone this repository along with the linked submodules, option --recursive has to be specified as shown below.

git clone --recursive https://github.com/STMicroelectronics/stm32u5-classic-coremw-apps.git

• To get the latest updates, issue the following two commands (with the repository stm32u5-classic-coremw-apps as the current working directory).

git pull
git submodule update --init --recursive

Note

• If GitHub "Download ZIP" option is used instead of the git clone command, then the required components have to be collected manually by the user.

Known Limitations

• USB Host application project can run correctly on NUCLEO-U575ZI-Q only after some hardware modifications:
  • Connect an external HSE clock circuitry on PH0 and PH1, to ensure HSE as source clock. Detailed schematic information can be found in this document
  • Add external circuitry allowing to provide Vbus (5V) source controlled by a GPIO from STM32U5 device (for example STMPS2141STR following the example of this board in sheet 7).

Troubleshooting
