Hello,
In stm32cubemx generated code there is the following routine.
void HAL_MspInit(void)
{
/* USER CODE BEGIN MspInit 0 */
/* USER CODE END MspInit 0 */
__HAL_RCC_SYSCFG_CLK_ENABLE();
HAL_NVIC_SetPriorityGrouping(NVIC_PRIORITYGROUP_4);
/* System interrupt init*/
/* MemoryManagement_IRQn interrupt configuration */
HAL_NVIC_SetPriority(MemoryManagement_IRQn, 0, 0);
/* BusFault_IRQn interrupt configuration */
HAL_NVIC_SetPriority(BusFault_IRQn, 0, 0);
/* UsageFault_IRQn interrupt configuration */
HAL_NVIC_SetPriority(UsageFault_IRQn, 0, 0);
/* SVCall_IRQn interrupt configuration */
HAL_NVIC_SetPriority(SVCall_IRQn, 0, 0);
/* DebugMonitor_IRQn interrupt configuration */
HAL_NVIC_SetPriority(DebugMonitor_IRQn, 0, 0);
/* PendSV_IRQn interrupt configuration */
HAL_NVIC_SetPriority(PendSV_IRQn, 15, 0);
/* SysTick_IRQn interrupt configuration */
HAL_NVIC_SetPriority(SysTick_IRQn, 15, 0);
/* USER CODE BEGIN MspInit 1 */
/* USER CODE END MspInit 1 */
}
Yet, in examples used (also with freeRTOS), I don't find similar initializations of priorities for this IRQs.
Is it really needed ? Why is it missing in examples ?
Thank you,
