HAL / LL Drivers updates
- Fixed known defects and several enhancements implementation.
- Enhanced HAL delay and time base implementation:
- Added new template stm32l1xx_hal_timebase_tim_template.c which can be used to override the native HAL time base functions (defined as weak) to use Timer as time base tick source.
- For more details about the usage of these drivers, please refer to HAL_TimeBase examples and FreeRTOS-based applications.
- The following drivers have been updated/reviewed and the changes require an update on the application code based on HAL V1.3.0:
- HAL CORTEX, LL DMA, HAL FLASH, HAL/LL GPIO, HAL/LL I2C, HAL PCD, HAL/LL PWR, HAL/LL RTC, HAL/LL SPI, HAL/LL TIM
- Refer to release notes for further details

- Update CMSIS-RTOS drivers to support both CMSIS Core V4.x and V5.x.
- Version full backward compatible with previous version FreeRTOS V8.2.3.
- Update CM0 ports, add possibility to use a timebase different than Systick.
- cmsis_os.c: Add support of Statically Allocated Systems introduced with FreeRTOS V9.0.0.
- cmsis_os.c: Add new wrappers CMSIS-RTOS APIs.
- Upgrade to new version of STemWin Library 5.32 (build 20160205)

HAL / LL Drivers updates
- Maintenance release to fix known defects.
- Low Layer drivers APIs provide register level programming: they require deep knowledge of peripherals described in STM32L1xx Reference Manual.
- Low Layer drivers are available for: ADC, COMP, CORTEX, CRC, DAC, DMA, EXTI, GPIO, I2C, IWDG, OPAMP, PWR, RCC, RTC, SPI, TIM, USART, WWDG peripherals and additional Low Level Bus, System and Utilities APIs.

Development Toolchains and Compilers
- IAR Embedded Workbench for ARM (EWARM) toolchain V7.20 + ST-LINK
- RealView Microcontroller Development Kit (MDK-ARM) toolchain V5.11 + ST-LINK
- A patch is provided to support STM32L152RExx under Utilities_Software-ARM_STM32L1xx_Patch.
- Important note: some of MDK-ARM projects were created with previous version like v4.73. If you are using MDK-ARM v5.10 (and later) you have to install a legacy patch to be able to open projects built with v4.73
- Atollic TrueSTUDIO STM32 (TrueSTUDIO) toolchain V5.1.1 + ST-LINK
- System Workbench for STM32 (SW4STM32) toolchain V1.2.0 + ST-LINK

Main Changes
Maintenance release
- Fix known defects and several enhancements implementation
Contents
HAL / LL Drivers updates
- Update drivers to be C++ compliant
- Add interfaces to access MPU features (refer to stm32l1xx_hal_cortex.h)
- Adding HAL_RCCEx_GetPeriphCLKFreq interface
- Adding interface HAL_TIM_SlaveConfigSynchronization_IT
- Add new interfaces for PWR:
- void HAL_PWR_EnableSleepOnExit(void);
- void HAL_PWR_DisableSleepOnExit(void);
- void HAL_PWR_EnableSEVOnPend(void);
- void HAL_PWR_DisableSEVOnPend(void);
- void HAL_PWR_EnableSleepOnExit(void);
- uint32_t HAL_PWREx_GetVoltageRange(void);
- Enhancement implementation. One change done on the HAL require an update on the application code based on HAL V1.1.0
- 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)
- Refer to release notes for further details
Middlewares updates
- USB Device V2.4.0: backward compatible with previous used version V2.3.0
- STemWin V5.26: project based on previous version V5.24 need to be updated following the change in the binary name
- ex. STemWin524b_CM4_IAR.a is renamed into STemWin526_CM4_IAR.a
- FatFs R0.10b: project based on previous version R0.10 need to update ffconf.h file (for more details please refer the associated release notes)
- FreeRTOS V8.1.2: project based on previous version V7.6.0 needs some update to work with version V8.1.2 (for more details please refer the associated release notes)
BSP Drivers updates
- Align BSP drivers with version V1.1.0 of HAL peripheral drivers
