Wake up from sys_poweroff() via GPIO. "Level" or "Edge" detection (SDK v2.9.0)

[uknoblic]

Dear Nordic team,

i am stilll struggeling with the GPIO set-up in system off mode. It seems, that both GPIO_INT_EDGE_TO_ACTIVE and GPIO_INT_LEVEL_ACTIVE are working fine (few µA). This contradicts with most of the ticktets i have looked at (and my own code where i tested this a few months ago!). Are there any changes in the SDK and / or the nrf52840 chip revisions which make this operate correctly now? I have set "sense-edge-mask" for the relevant pins.

#if 1

    if (flux_detect_event == EV_FLUX_DETECTED)
    {
      err = gpio_pin_interrupt_configure_dt(gpio_dt_spec_flux_detect,
                                            GPIO_INT_EDGE_TO_ACTIVE);
    }
    else
    {
      err = gpio_pin_interrupt_configure_dt(gpio_dt_spec_flux_detect,
                                            GPIO_INT_EDGE_TO_INACTIVE);
    }

#else

    if (flux_detect_event == EV_FLUX_DETECTED)
    {
      err = gpio_pin_interrupt_configure_dt(gpio_dt_spec_flux_detect,
                                            GPIO_INT_LEVEL_ACTIVE);
    }
    else
    {
      err = gpio_pin_interrupt_configure_dt(gpio_dt_spec_flux_detect,
                                            GPIO_INT_LEVEL_INACTIVE);
    }
