DETECT Signal Is Not Bringing System Out Of Systemoff State

[davidb]

I'm using an nRF52840 and SDKv17.1.

I have an active-high interrupt source connected to a GPIO pin. I understand that a GPIO should be able to wake up a system from system-off state. The interrupt source is an accelerometer.

I use this GPIO configuration:

err_code = nrf_drv_gpiote_init();
APP_ERROR_CHECK(err_code);

nrf_drv_gpiote_in_config_t PIN_INT1_config = NRFX_GPIOTE_CONFIG_IN_SENSE_LOTOHI(true);

PIN_INT1_config.pull = NRF_GPIO_PIN_PULLUP;

err_code = nrf_drv_gpiote_in_init(NRF_GPIO_PIN_MAP(1, 5), &PIN_INT1_config, adxl372_int1_pin_handler);
APP_ERROR_CHECK(err_code);

nrf_drv_gpiote_in_event_enable(NRF_GPIO_PIN_MAP(1, 5), true);

I have tested this using sleep mode and it works as expected. When I use NRF_POWER->SYSTEMOFF the system does not power-on.

Is there a GPIO configuration issue here?

My code snip above shows I use NRFX_GPIOTE_CONFIG_IN_SENSE_LOTOHI(true);

I also added nrf_gpio_cf_sense_set(NRF_GPIO_PIN_MAP(1, 5), NRF_GPIO_PIN_SENSE_HIGH);

That did not help though.

I tested this code in an application, and I'm not having any issues with waking the chip from System OFF using this APIs.

Can you please post your full project for us to reproduce and debug it?
