MX_TouchGFX_PreOSInit() called before I can init my external (QSPI) Flash

[MHoll.2]

The STM32CubeMX generated main.c has the function MX_TouchGFX_PreOSInit() called directly after the MX_xxx_Init() functions, before I can insert my External Flash Initialisation (in /* USER CODE BEGIN 2 */).

This prevents the use of the External Flash for the TextFlashSection defined by TouchGFX.

It would be better to call MX_TouchGFX_PreOSInit() immediatly before MX_xxx_Init() (in my case  MX_ThreadX_Init()).

Hello @MHoll.2 

What MCU are you using? Or could you provide your IOC in order to investigate further the issue.

Hi Souhaib,

I'm using the STM32H725IEK.

Attached a small example ioc file that generates

/**
 * @brief The application entry point.
 * @retval int
 */
int main(void)
{

 /* USER CODE BEGIN 1 */

 /* USER CODE END 1 */

 /* MPU Configuration--------------------------------------------------------*/
 MPU_Config();

 /* 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_OCTOSPI1_Init();
 /* Call PreOsInit function */
 MX_TouchGFX_PreOSInit();
 /* USER CODE BEGIN 2 */

 /* USER CODE END 2 */

 MX_ThreadX_Init();

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

 /* Infinite loop */
 /* USER CODE BEGIN WHILE */
 while (1)
 {
 /* USER CODE END WHILE */

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

  I'm using STMCubeIDE 1.18.1, beause of  this problem:  https://community.st.com/t5/stm32cubeide-mcus/stm32cubeide-1-19-0-problem-migrating-octospi2-stm32h730-from-1/td-p/819983

Hello @MHoll.2 

As my understanding you can initialize the External flash inside the MX_OCTOSPI1_Init() (/* USER CODE BEGIN OCTOSPI1_Init 2 */). This will ensure that the external flash is initialized before the call of MX_TouchGFX_init.
