[S32K3] external GPIO Interrupt example

[Changhawn]

Dear

I'm trying to use one of the GPIO pins as an interrupt with an external chip,

Is there an example of registering an interrupt?

The below sequence is based on references from the NXP community, but I'm asking because it doesn't seem to work well.

If there's no example, could you please check if the below is correct?

Thank u~

1. GPIO configuation

2. register interrupt to intCtrl_Ip 

3.  SIUL2_ICU , add 

4.  SW

I have confirmed this issue. 

Because one api was missed.

Hi Changhawn,

It looks like you have referred to the SIUL2 external interrupt example project using S32K3 RTD without AUTOSAR.

Have you added "6. Add Siul2_Icu LLD APIs"?

There may be some differences due to different RTD versions. Could you please tell me the S32K3 RTD version and S32K3 part number? If you are using S32K3 development board, please tell me which development board you are using.

Best Regards,
Robin

Dear Robin.

Yes. I added "6. Add Siul2_Icu LLD APIs" as callback function.

My test RTD Version is 3.0.0 of S32K314.  And this is our development board.

Thank u
