RE: nrf9160 GPIOTE with Interrupt

Can you add some debugging by:

CONFIG_ASSERT=y

CONFIG_ASSERT_VERBOSE=y

CONFIG_ASSERT_NO_COND_INFO=n

CONFIG_ASSERT_NO_MSG_INFO=n

CONFIG_RESET_ON_FATAL_ERROR=n

Hi kenneth,

Thank you very much,

The only change i done to your code is IRQ_CONNECT(GPIOTE1_IRQn, 7, nrfx_isr, nrfx_gpiote_irq_handler, 0); (of course i changed CONFIG_GPIO=n also)

but i didnt understand one thing, when i use GPIOTE0_IRQn in above function the board is restarting, im using port 0 for the gpio but still why its happening like that?

I believe you will need to set: CONFIG_GPIO=n, else zephyr will control the GPIOTE peripheral (thereby no interrupt).

This example I made some time ago should show an example how it can be done:
