STM32CubeMX 6.6.1 "Generate Enable in Init" does not work as expected for external interrupts

FLomb.2 · ‎2022-07-18

When attempting to initialize a single GPIO EXTI as disabled, the generated code still enables the interrupt. I did notice that if I uncheck all of the EXTI lines, then none of them are enabled in the generated code. So it seems it's all or nothing. Is this the expected behavior?

Thanks,

Frank

This:

Generates:

  /* EXTI interrupt init*/
  HAL_NVIC_SetPriority(EXTI0_IRQn, 5, 0);
  HAL_NVIC_EnableIRQ(EXTI0_IRQn);
 
  HAL_NVIC_SetPriority(EXTI2_IRQn, 6, 0);
  HAL_NVIC_EnableIRQ(EXTI2_IRQn);
 
  HAL_NVIC_SetPriority(EXTI3_IRQn, 6, 0);
  HAL_NVIC_EnableIRQ(EXTI3_IRQn);
 
  HAL_NVIC_SetPriority(EXTI4_IRQn, 6, 0);
  HAL_NVIC_EnableIRQ(EXTI4_IRQn);

However, this:

Generates:

  /* EXTI interrupt init*/
  HAL_NVIC_SetPriority(EXTI0_IRQn, 5, 0);
  HAL_NVIC_SetPriority(EXTI2_IRQn, 6, 0);
  HAL_NVIC_SetPriority(EXTI3_IRQn, 6, 0);
  HAL_NVIC_SetPriority(EXTI4_IRQn, 6, 0);

Hello @FLomb.2 (Community Member) & @KnarfB (Community Member) ,

Thanks for your feedback,

This is a known issue and it is already raised to the dev team. When "Generate enable in init" is unchecked, its respective HAL_NVIC_EnableIRQ(XXXX_IRQn) should not be generated.

I will keep you posted with updates

Confirmed on NUCLEO_STM32G431KB PA4 and PB0. Flagged as bug-report.
