Errors with my project

[Peter57]

From a previous discussion and new thread created for new question:

Hello, thank you for your early reply.
I'm missing the STM32F429I_DISCO_REV_E01.ioc  file.
I try to add same simple Code to the Mail file in User section...

/* Infinite loop */

/* USER CODE BEGIN WHILE */

while (1)

// HAL_GPIO_TogglePin(GPIOx, GPIO_Pin)

HAL_GPIO_TogglePin(GPIOG, 13); // LED I want to look for LD3 ore LD4

/* USER CODE END WHILE */

/* USER CODE BEGIN 3 */

/* USER CODE END 3 */

I got this error message....

If I debug the Programm I got the Errors in the grafik.png, and the programm look like Stop.

I can't find the LD3 and the LD4 in the AutoCompled ....
so I think they are not configured. May be this a problem of mine, I don't anderstand

And short before I write my code, i see this comment

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

Now I add the by "STM32 from a existing STM32CubeMX.ioc file.
after it. This will work with no error. Than i config GPIOG_pin13 and Build again, lots off errors occure.

How i can change the STMCubeMX file ?

Sorry, for the time you spend. Hope we mamage the Problem.

Thank you in advance , Peter
