LIS2DH Trigger Giving z_arm_mpu_fault()LIS2

[NautDesigner]

Running the Zephyr LIS2DH sample program on a custom board works fine until I configure it to use the trigger and then it throws the z_arm_mpu_fault() error. It doesn't matter if I have it use it's own thread or the global thread. 

Any idea what could be causing this?

Yes, that's how you do it. Check how it's done here: https://github.com/nrfconnect/sdk-zephyr/blob/v2.4.99-ncs2/boards/arm/nrf9160_innblue21/nrf9160_innblue21_common.dts#L98.

It is often helpful to search trough NCS/Zephyr to figure out how stuff are done, either by using the search tools of an IDE, or the git grep command. Now I simply typed in git grep irq-gpios in the Zephyr repo and found the above.

Best regards,

FYI opened a bug about this: https://github.com/zephyrproject-rtos/zephyr/issues/34794

I think previously if INT2 was not defined, it would fail gracefully. Something in the device tree API has changed which causes Zephyr to fault.

Thanks for the help.
