【STM32】FreeRTOS开启后，不再进入主函数的while(1)

开启freertos后，想在主函数的while(1)中实现led的翻转，发现无法实现。

cpp 复制代码

int main(void)
{
  /* USER CODE BEGIN 1 */

  /* USER CODE END 1 */

  /* MCU Configuration--------------------------------------------------------*/

  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  HAL_Init();

  /* USER CODE BEGIN Init */

  /* USER CODE END Init */

  /* Configure the system clock */
  SystemClock_Config();

  /* USER CODE BEGIN SysInit */

  /* USER CODE END SysInit */

  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  MX_USART1_UART_Init();
  /* USER CODE BEGIN 2 */

  /* USER CODE END 2 */

  /* Call init function for freertos objects (in freertos.c) */
  MX_FREERTOS_Init();

  /* Start scheduler */
  osKernelStart();

  /* We should never get here as control is now taken by the scheduler */
  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  while (1)
  {
		HAL_GPIO_TogglePin(GPIOF,GPIO_PIN_9);
		HAL_Delay(1000);
    /* USER CODE END WHILE */

    /* USER CODE BEGIN 3 */
  }
  /* USER CODE END 3 */
}

分析原因：

cpp 复制代码

osKernelStart();

  /* We should never get here as control is now taken by the scheduler */

osKernelStart();

语句后面有一个注释：

/* We should never get here as control is now taken by the scheduler */

我们永远不会到达这里，因为控制权现在被调度器拿走了
