Timer based example on docu using nrf52-dk compile error.

[XlashDev]

Hi I'm new with using zephyr and maybe a noob question. I'm using nrf52-dk via platformio. Been scratching and googling but can't find answer. I just copied the example timer expiry on zephyr documentation but this shows up and I can't fix it. I need the timer to work every 50ms. It says declaration incompatible pointing to the kernel.h file.

TIA

kernel.h file

Closing this. Solved it by moving it to main.
