Nucleo-U5A5ZJ-Q and RNG code generation

[DenzilDexter]

Hello Community,

I have a Nucleo-U5A5ZJ-Q development board and have generated code for it using CubeMX (version 6.12.0).  The generated code contains this for the user button:

void EXTI13_IRQHandler(void)
{
  /* USER CODE BEGIN EXTI13_IRQn 0 */

  /* USER CODE END EXTI13_IRQn 0 */
  BSP_PB_IRQHandler(BUTTON_USER);
  /* USER CODE BEGIN EXTI13_IRQn 1 */

  /* USER CODE END EXTI13_IRQn 1 */
}

 If I enable the RNG in CubeMX and enable its global interrupt and then re-generate the code the above changes to:

void EXTI13_IRQHandler(void)
{
  /* USER CODE BEGIN EXTI13_IRQn 0 */

  /* USER CODE END EXTI13_IRQn 0 */
  HAL_EXTI_IRQHandler(&H_EXTI_13);
  /* USER CODE BEGIN EXTI13_IRQn 1 */

  /* USER CODE END EXTI13_IRQn 1 */
}

Which doesn't compile as H_EXTI_13 is not defined anywhere that I can see in any file.  am I missing something or is this a glitch in CubeMX. If I restore line 6 to its original value then the code compiles.

Any help much appreciated.

Hello @DenzilDexter ,

First let me thank you for posting and welcome to the ST Community.

For more investigation, I suggest that you provide your Ioc.File.

Thanks.

Hi @DenzilDexter,

I reproduced the same example that you did and I didn't have any problems after enabling RNG.

Here is a screenshot before enabling RNG:

and her is a screenshot after enabling RNG:

I think you should update the version of CubeMx that you are using (the latest version is 6.14.1).

Thank you.

Hello Mahmoud,
Here's the IOC file. As an aside I can make things work by defining this:

#define H_EXTI_13 hpb_exti[BUTTON_USER]

in the file `stm32u5xx_it.c` in a user code section.  
Thanks for the help,
DD
