What is MX__Init()?????

[svcguy]

Have a project using CubeMX 5.5.0 from within CubeIDE 1.2.1 on Windows 10 for an STM32F767 using FW 1.15.0. Its a TouchGFX project so it, by default uses FreeRTOS. Whenever I regenerate code, I get this in the DefaultTask:

/* USER CODE BEGIN Header_StartDefaultTask */
/**
  * @brief  Function implementing the defaultTask thread.
  * @param  argument: Not used 
  * @retval None
  */
/* USER CODE END Header_StartDefaultTask */
void StartDefaultTask(void const * argument)
{
  /* init code for */
  MX__Init();
  /* USER CODE BEGIN StartDefaultTask */
  printf("\tStarting default task...\n");
 
  /* Infinite loop */
  for(;;)
  {
    HAL_GPIO_TogglePin(LED_GPIO_Port, LED_Pin);
    osDelay(500);
  }
  /* USER CODE END StartDefaultTask */
}

The pin toggle is of course user code but what is MX__Init()? Note two underscores between MX and Init. I thought maybe it was a typo and is supposed to be MX_Init() but there is no function named that either? Is this supposed to be code that is run or a bug/typo?

*.ioc file is attached

That is a bug. I used to get that same line of code though I haven't seen it lately. I believe that line should be to init the USB host

/* USER CODE BEGIN Header_StartDefaultTask */
/**
  * @brief  Function implementing the defaultTask thread.
  * @param  argument: Not used 
  * @retval None
  */
/* USER CODE END Header_StartDefaultTask */
void StartDefaultTask(void const * argument)
{
  /* init code for USB_HOST */
  MX_USB_HOST_Init();
  /* USER CODE BEGIN 5 */
  /* Infinite loop */
  for(;;)
  {
    osDelay(1);
  }
  /* USER CODE END 5 */ 
}

​Well , issue seems fixed on the 5.6.0 CubeMX version, so you will receive the fix in the next release (which is planned in W08).

Thank you again for your feedback.
