Release Notes for STM32CubeH7 Firmware Package

Purpose

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

STM32Cube covers STM32 portfolio.

STM32Cube Version 1.x includes:

The STM32CubeMX, a graphical software configuration tool that allows to generate C initialization code using graphical wizards.
A comprehensive embedded software platform, delivered per series (such as STM32CubeH7 for STM32H7 series)
- The STM32Cube HAL, an STM32 abstraction layer embedded software, ensuring maximized portability across STM32 portfolio
- A consistent set of middleware components such as RTOS, USB, TCP/IP, Graphics]

All embedded software utilities come with a full set of examples.

The STM32Cube firmware solution offers a straightforward API with a modular architecture, making it simple to fine tune custom applications and scalable to fit most requirements.

The drivers provided within this package support the STM32H743/753/750/745/755/747/757/742/7A3/7B0/ 7B3/723/725/733/735/730 lines.

The HAL and LL drivers provided within this package are compliant with MISRA-C®:2012 guidelines, and have been reviewed with a static analysis tool to eliminate possible run-time errors. Reports are available on demand.

Main Changes

Maintenance release

General updates to fix known defects and implementation enhancements.
The following changes done on the HAL drivers require an update of the application code based on older HAL versions
- Rework of HAL Ethernet driver to resolve problems and improve performance.(compatibility break)
- A new HAL Ethernet driver has been redesigned with new APIs, to bypass limitations with previous HAL Ethernet driver version.
- The new HAL Ethernet driver is the recommended version. It is located as usual in Drivers/STM32H7xx_HAL_Driver/Src and Drivers/STM32H7xx_HAL_Driver/Inc folders.
  - It can be enabled through switch HAL_ETH_MODULE_ENABLED in stm32h7xx_hal_conf.h
- The legacy HAL Ethernet driver is also present in the release in Drivers/STM32H7xx_HAL_Driver/Src/Legacy and Drivers/STM32F4xx_HAL_Driver/Inc/Legacy folders for software compatibility reasons.
  - Its usage is not recommended as deprecated. It can however be enabled through switch HAL_ETH_LEGACY_MODULE_ENABLED in stm32h7xx_hal_conf.h
\HAL Please Refer to the release notes for details.
- Rework Ethernet driver to resolve problems and improve performance.
\Middleware:
- Update of USB Device library to new version V2.10.0
- Update of USB host library to new version V3.4.0

- Update projects to avoid using MPU write through configuration
  - Use non cachebale configuration instead when a memory region is accessed by the DMA and by the Cortex-M7 (in write only)
  - Only the SDRAM regions used as LCD frame buffer are configured in write through which is safe as the Cortex-M7 will perform write access without immediate read access to these regions
- Update PWR/PWR_STOP_RTC examples to add voltage scale configuration after wake-up from stop mode
- Update SD/SD_ReadWrite_DMA , SD/SD_ReadWrite_IT and SD/SD_ReadWrite_DMA_HS examples to avoid waiting on card ready inside the Rx/Tx callbacks

Main Changes

Official release to add Demonstration Firmware for STM32H743I_EVAL.
General update to fix known defects and several implementations enhancement
CMSIS
- Update USB OTG bit definition.
- Adjust PLL fractional computation.
HAL
- HAL FLASH: Add Mass Erase for both banks.
- HAL RCC
  - Update RCC_PeriphCLKInitTypeDef structure for more IP clock selection flexibility.
  - Adjust PLL fractional computation.
- HAL SPDIFRX: Add symbol clock generation.
BSP
- Update STM32H7xx_Nucleo_144 and STM32H743I_EVAL drivers.
Middleware
- Update to new version of FreeRTOS V9.0.0 MPU
- Update to use the new version of StemWin V5.40
  - Note: Applications based on previous version StemWin V5.32 require update to cope with the upgrade to the currently used 5.40. For details please refer to its Release Note and to the updated StemWin applications provided by this firmware package.
- Update to new version of FatFs R0.12c
Projects
- Update projects to support new FatFs and STemWin versions.
- Add new FreeRTOS MPU application running on STM32H743I_EVAL and STM32H7xx_Nucleo_144, only EWARM Toolchain is supported.
- Add FWupgrade_Standalone and HID_LPM_Standalone applications running on STM32H743I_EVAL.
- Add Demonstration Firmware for STM32H743I_EVAL.
- Note:
  - Demonstrations Firmware for STM32H743I_EVAL provided within this package, don’t embed:
    - TouchGFX demonstration module. Free evaluation version of the TouchGFX demonstration, based on Draupner Graphics’ commercial graphic library, is available at www.touchgfx.com/stmicroelectronics
    - Embedded Wizard demonstration module. Free evaluation version of the TARA Systems demonstration, is available at www.embedded-wizard.de/stm32
