STM32U0 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, FatFS, and LwIP

Note

This package is exclusively published on GitHub (and is neither available in STM32CubeMX nor STM32CubeIDE available on www.st.com). It contains the integration of the Classic CoreMW stacks with STM32U0 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 STM32U0 Classic CoreMW package contains the following applications:

Middleware	Application	Short Description
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

Note

• FreeRTOS Middleware and examples are delivered on STM32U0 in the form of X-CUBE-FREERTOS that is available from st.com, from GitHub and from STM32CubeMX.
• Only HID_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).

Boards available

• STM32U0
  • STM32U083C-DK RevC

Development Toolchains and Compilers

• IAR Embedded Workbench for ARM (EWARM) toolchain 9.20.1 + ST-LINKV3, patch available here.
• RealView Microcontroller Development Kit (MDK-ARM) toolchain V5.39 + ST-LINKV3, Patch available here.
• [STM32CubeIDE V2.1.0] + ST-LINKV3

Dependencies

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

Name	Version
Cortex-M CMSIS	v5.9.0_fix_620_dsp_v1.10.0_nn_v3.1.0_no_doc
STM32U0xx CMSIS	V1.3.0
STM32U0xx HAL	V1.3.0
BSP STM32U083C DK	V1.1.0
BSP Common	V7.3.0
STM32 USB Device Library	V2.11.5

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

• 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/stm32u0-classic-coremw-apps

• To get the latest updates, issue the following two commands (with the repository stm32u0-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

• None
