When I generated code for STM32H5 using SysTick selected as time base for HAL, HAL delay doesn't work. Yes, I know about the warning, I know limitations and I fine with that... when it works. But it doesn't. The reason why it doesn't work that next line uncommented in FreeRTOSConfig.h:
#define SysTick_Handler xPortSysTickHandler
and SysTick_Handler doesn't generated by STM32CubeMX. This how it handled for STM32F1 series. FreeRTOSConfig.h:
/* IMPORTANT: This define is commented when used with STM32Cube firmware, when the timebase source is SysTick,
to prevent overwriting SysTick_Handler defined within STM32Cube HAL */
/* #define xPortSysTickHandler SysTick_Handler */
And SysTick_Handler added to stm32f1xx_it.c:
/**
* @brief This function handles System tick timer.
*/
void SysTick_Handler(void)
{
/* USER CODE BEGIN SysTick_IRQn 0 */
/* USER CODE END SysTick_IRQn 0 */
HAL_IncTick();
#if (INCLUDE_xTaskGetSchedulerState == 1 )
if (xTaskGetSchedulerState() != taskSCHEDULER_NOT_STARTED)
{
#endif /* INCLUDE_xTaskGetSchedulerState */
xPortSysTickHandler();
#if (INCLUDE_xTaskGetSchedulerState == 1 )
}
#endif /* INCLUDE_xTaskGetSchedulerState */
/* USER CODE BEGIN SysTick_IRQn 1 */
/* USER CODE END SysTick_IRQn 1 */
}
