Maintenance release

Main Changes

  • Maintenance release to fix known defects and several enhancements implementation

  • HAL
    • Macros and literals renaming to ensure full compatibility across STM32 series, backward compatibility with HAL V1.0.1 maintained thanks to new added file stm32_hal_legacy.h under /Inc/Legacy
    • Fix known defects and several enhancements implementation. Four changes done on the HAL requires an update on the application code based on HAL V1.0.1
      • LSI_VALUE constant has been corrected in stm32f2xx_hal_def.h file, its value changed from 40 KHz to 32 KHz
      • UART, USART, IRDA and SMARTCARD (referenced as PPP here below) drivers: in DMA transmit process, the code has been updated to avoid waiting on TC flag under DMA ISR, PPP TC interrupt is used instead. Below the update to be done on user application:
        • Configure and enable the USART IRQ in HAL_PPP_MspInit() function
        • In stm32f2xx_it.c file, PPP_IRQHandler() function: add a call to HAL_PPP_IRQHandler() function
      • HASH IT process: update to call the HAL_HASH_InCpltCallback() at the end of the complete buffer instead of every each 512 bits
      • HAL CRYP driver updated to support multi instance, so user must ensure that the new parameter Instance is initialized in his application(CRYPHandle.Instance = CRYP)
    • Update drivers to be C++ compliant
    • Several update on source code formatting, for better UM generation (i.e. Doxygen tags updated)
    • Add *.chm UM for all drivers, a UM is provided for each superset RPN
  • CMSIS

  • General updates to fix known defects and enhancements implementation

  • Middlewares
    • Updated USB Device V2.4.1: fix known defects and several enhancement implementation
    • Updated USB Host V3.2.2: fix known defects and several enhancement implementation
  • BSP
    • Update STM322xG-EVAL BSP driver to support the cs43l22 audio codec component
  • Projects
    • Add more Examples and Applications for STM322xG_EVAL board (47 in total)
    • Add the support of System Workbench for STM32 (SW4STM32) toolchain
