Maintenance release

Main Changes

• Patch release to mainly fix the eventual compilation regression introduced in the HAL SDMMC driver with the STM32Cube V1.28.2 package.
• HAL ETH driver V1.8.4, included in STM32CubeF4 V1.28.2, breaks compatibility with previous versions and requires updating application code based on older HAL ETH driver versions:
  • The HAL_ETH_SetMACFilterConfig() API was updated to fix the enable/disable broadcast filter configuration.
  • When porting an application to the new HAL ETH driver, configure the MAC filter as follows:
    • Set BroadcastFilter = DISABLE to allow reception of broadcast packets.
    • Set BroadcastFilter = ENABLE to block reception of broadcast packets.
• HAL
  • HAL SDMMC
    • Update to use dedicated MMC defines in the HAL SDMMC driver.
  • HAL FLASH
    • Initialize the ‘pFlash’ variable with default values.
• For the complete list of changes, please refer to the release notes of each firmware component

Maintenance release

Main Changes

• Thanks to the acquisition of Draupner Graphics A/S, ST is extending the STM32 ecosystem with advanced and easy to use graphic software solution enabling stunning GUI additions to embedded devices. TouchGFX solution is now fully part of STM32CubeF4.

• TouchGFX examples and demonstrations can be accessed directly through the TouchGFX Designer tool. Here you simply create a new project, select the appropriate ST board in the Application Template section and select whatever demonstration or example you want in the UI Template selector. After this you will have a TouchGFX application ready to compile and flash to the selected ST board. More information are available here

• Middleware

  • This version is not backward compatible with previous V3.0.0 and earlier version, below the list of complete changes requiring updates on User applications:
    • libPDMFilter_CM4_IAR.a updated and renamed to:
      • libPDMFilter_CM4_IAR_wc32.a for EWARM V8.x and later versions.
