CubeMX STM32MP1 NVIC EXTI disabled ?

[debugging]

1 Select STM32MP151 (This case AAAx)

2. Select an GPIOx and set to GIPIO_EXTx

3. Goto NVIC: EXTI option is disabled

  (Checkbox cannot be selected)

4. Goto GPIO : Pin can be configured as interrupt

How to enable interrupts for NVIC for GPIO's in order to generate the code ? See pictures. CubeMX 5.3.0, Linux

Hi @debugging​ 

it seems you have miss one step :

1 Select STM32MP151 (This case AAAx)

2. Select an GPIOx and set to GIPIO_EXTx

3.Select again GPIO under Pinout View, right click -> Pin Reserved -> Cortex-M4

4. Goto NVIC: EXTI option checkbox can now be selected

Indeed, this is not obvious and not well documented. We will work to enhance this.

Hope it help

Hello Olivier ,

Many thanks. That worked.

Being on this topic, snipped of the code:

EXTI_ConfigStructure.Trigger = EXTI_TRIGGER_FALLING;

HAL_EXTI_RegisterCallback(&hexti, HAL_EXTI_FALLING_CB_ID, Callback);

But , no matter what, the default handler is called and not the custom function Callback.

Thanks!

Hi @debugging​ 

Could you refer to Cube Package example

STM32Cube_FW_MP1_V1.0.1\Projects\STM32MP157C-DK2\Examples\GPIO\GPIO_EXTI

And check what may be wrong in the IT configuration ?

Thanks

Olivier

CLOSED, First need right click on the pin and select Cortex M4
