TIM2 Interrupt deleted when setting EXTI[9:5] interrupt

[Fin95]

Hi all,

I am using a nucleo board F412ZG with the Middelware FreeRTOS. I use only one task for now, but I will use others in future.

By the way, I set TIM2 as the timer system for FreeTOS:

Now I am trying to enable pin PC8 as an external interrupt in order to detect a falling edge:

When I generate the code I notice that the TIM2 interrupts is deleted, but I do not understand why. Anyone can help me?

Below I leave the screens of the generated code modifies from git:

Hello @Fin95 

I'm currently checking this behavior . I will get back to you asap.

Could you please provide your IOC?

Hello @Fin95 

You are using STM32CubeMX 6.14.1 , I recommend you to migrate to the latest version of CubeMX 6.16.0 .

When you configure FreeRTOS to use TIM2 as the tick timer (instead of the default SysTick), CubeMX takes control of the TIM2 interrupt for the RTOS kernel. This means: CubeMX will generate the TIM2 interrupt handler (TIM2_IRQHandler) in stm32f4xx_it.c as shown below

Hi @Ghofrane GSOURI,

I have installed the new version of CubeMX and from the autogenerated files seems the TIM2 interrupt callback is not even more deleted! ASAP I test the fw, I will check if it works properly and I will reply again to confirm the bugfix.

Thanks for the help.

Best regards.
