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: FatFS
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:
| Middleware |
Application |
Short Description |
| FatFs |
FatFs_RAMDISK_Standalone |
Shows a typical application where the STM32 MCU write and read back a Fat Format text file from RAMDISK |
| ST USB Device |
CDC_Standalone |
Shows how to use USB device application based on the Device Communication Class (CDC) following the PSTN |
| ST USB Device |
HID_Standalone |
Shows a typical application where the STM32 MCU is enumerated as a HID device |
| ST USB Device |
DFU_Standalone |
Shows a typical application where the STM32 MCU is enumerated as a DFU device |
| ST USB Host |
HID_Standalone |
Shows how to use USB host application based on the Human Interface Class (HID) to connect a mouse or a keyboard |
| ST USB Host |
MSC_Standalone |
Shows how to use USB host application based on the Mass Storage Class (MSC) to communicate with a usb flash disk |
Note
- FreeRTOS Middleware and examples are delivered on STM32U5 in the form of X-CUBE-FREERTOS that is available from st.com, from GitHub and from STM32CubeMX.
- Only FatFs_RAMDISK_Standalone application is provided with preconfigured projects for EWARM, 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).

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.
- 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:
- 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
Please refer to the CONTRIBUTING.md guide.
