HAL_GPIO_EXTI_Callback() defined multiple times, assume it is an error in CubeMX 6.2.0 - STM32F4 FW 1.26?

@STM32 MCUs​

In our project we use USB_CDC. We don't use VBUS, disabled at all places in CubeMX, as far as I can see.

Now we want to add an external interrupt on PC0. I have done this.

CubeMX generates the following code, already before I added external interrupt:

usbd_conf.c

/**

* @brief Handle USB VBUS detection upon external interrupt

* @param GPIO_Pin

* @retval None

*/

void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)

{

if (GPIO_Pin == GPIO_PIN_9)

{

HAL_PCDEx_BCD_VBUSDetect(&hpcd_USB_OTG_FS);

}

}

This function is needed to define a callback for the external interrupt.

Because I have disable VBUS, I assume this function shall not be in generated code?

I found the same bug report already a few times in forum, partly going back to 2018.

Why was it not yet fixed? The bug reports from the past are closed,

but how was the fix?

Best regards,
