Adding External interrupt to RT1170 platform.

[krishnad]

Hi,

I am trying to interrupt RT1170 (running MCUxpresso) from another board using a gpio line. With the limited exposed pins on RT1170 connectors (all pins of J9,J10, J25, J26), which pins in connectors J9,J10, J25, J26 can be used for this purpose. I am looking at something similar to evkmimxrt1170_igpio_input_interrupt_cm7 project where the interrupt is connected to a dedicated WAKEUP pin, that is something i don't want to use.

Going through the pin config tools seem never ending complex process to me. Any help is highly appreciable. Thanks in advance.

Hello
Hope you are well.
I suggest you use Config Tools to configure the pins in GPIO, at the Label column you can see which connector the board has assigned for a specific pin. E.g. here GPIO11_IO11 is routed to J9[4]:

To configure the specific interrupts you can do it based on the example provided in the SDK modifying the macro's value to match your used GPIO´s.

If you have more questions do not hesitate to ask me.
Best regards,
Omar
