学习消息队列，调用freertos中断API函数时，出现了问题，调试追踪发现卡死在portASSERT_IF_INTERRUPT_PRIORITY_INVALID();这个宏，该如何解决呢。 其中主要是两个中断，配置如下： HAL_NVIC_SetPriorityGrouping(NVIC_PRIORITYGROUP_4); HAL_NVIC_SetPriority(EXTI4_IRQn, 7, 0); // 对应是 CLK_CHECK_Pin 中断 HAL_NVIC_EnableIRQ(EXTI4_IRQn); HAL_NVIC_SetPriority(EXTI9_5_IRQn, 10, 0); // 对应是 B2A_Pin 中断 HAL_NVIC_EnableIRQ(EXTI9_5_IRQn);其中CLK_CHECK_Pin 中断发生时都能正常响应，就是当B2A_Pin 中断来临时出现卡死portASSERT_IF_INTERRUPT_PRIORITY_INVALID();这里，我的系统中实时性高，没法用printf来进行调试，只有通过逻辑分析仪和翻转LED来进行调试，已经尝试更改了B2A_Pin了的优先级设置为 HAL_NVIC_SetPriority(EXTI9_5_IRQn, 0, 0); // 对应是 B2A_Pin 中断 HAL_NVIC_EnableIRQ(EXTI9_5_IRQn);还是死机，暂时不晓得咋处理，现在唯一的解决方式在B2A_Pin 中断发生时不使用freertos相关API。来平台主要是想问一下有没有人碰到过类似的事情，如何解决的，同时是方便自己对freertos的理解 相关的业务的代码如下： #include "business_task.h" #include "main.h" #include osThreadId businessTaskHandle; osMessageQId businessQueueHandle; // 业务任务的入口函数 void StartBusinessTask(void const * argument) { uint32_t data = 0; // 在这里编写任务的代码 while (1) { // 从消息队列中获取数据 osEvent event = osMessageGet(businessQueueHandle, osWaitForever); data = event.value.v; // 处理数据并进行相应的操作 if (data == CLK_CHECK_Pin) { do_something(); // 这里需要很长时间来进行处理 } else if(data == B2A_Pin) { HAL_GPIO_TogglePin(LED2_GPIO_Port,LED2_Pin); } } } // void SetBusinessQueueHandle(osMessageQId queue_id) // { // // 将消息队列句柄保存到全局变量中 // businessQueueHandle = queue_id; // } // 初始化业务任务 void InitBusinessTask(void) { osThreadDef(businessTask, StartBusinessTask, osPriorityRealtime, 0, 128); businessTaskHandle = osThreadCreate(osThread(businessTask), NULL); osMessageQDef(businessQueue, 16, uint32_t); // 将队列的最大容量设置为 16 businessQueueHandle = osMessageCreate(osMessageQ(businessQueue), NULL); // 将业务任务的消息队列句柄传递给中断处理函数 // SetBusinessQueueHandle(businessQueueHandle); } // 向业务任务发送数据 bool SendDataToBusinessTask(uint32_t data) { if (osMessagePut(businessQueueHandle, data, 0) != osOK) { return false; } return true; } void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { if (GPIO_Pin == CLK_CHECK_Pin) { SendDataToBusinessTask(CLK_CHECK_Pin); } else if (GPIO_Pin == B2A_Pin) { // HAL_GPIO_TogglePin(LED2_GPIO_Port,LED2_Pin); SendDataToBusinessTask(B2A_Pin); } }FreeRTOSConfig.h的内容如下： /* USER CODE BEGIN Header */ /* * FreeRTOS Kernel V10.0.1 * Copyright (C) 2017 Amazon.com, Inc. or its affiliates.
