nrf connect sdk on nrf9161 using GPIOTE fails to build

[Mart]

I want to use gpiote and functions like:

- nrfx_gpiote_input_configure

- nrfx_gpiote_in_event_enable

This is added to the top of my document:

#include <nrfx_gpiote.h>

However, my build says:

'nrfx_gpiote_in_event_enable' was not declared in this scope; did you mean 'nrfy_gpiote_event_enable'

Why is that? 

When, in my prj.conf, I add the line:

CONFIG_NRFX_GPIOTE=y

For some reason, my build fails with:

error: NRFX_GPIOTE (defined at C:/ncs/v2.9.0/zephyr/modules/hal_nordic\nrfx/Kconfig:169,
modules\hal_nordic\nrfx/Kconfig:169) is assigned in a configuration file, but is not directly user-
configurable (has no prompt). It gets its value indirectly from other symbols. See
docs.zephyrproject.org/.../kconfig.html and/or look up NRFX_GPIOTE in
the menuconfig/guiconfig interface. The Application Development Primer, Setting Configuration
Values, and Kconfig - Tips and Best Practices sections of the manual might be helpful too.

I'm running vs code and sdk toolchain v2.9.0 along with nRF Connect SDK v2.9.0

Hello,

'''nrfx_gpiote_in_event_enable' was not declared in this scope; did you mean 'nrfy_gpiote_event_enable'

Why is that''

From the NCS v2.5.2, the NRFX GPIOTE driver API has changed. The function nrfx_gpiote_in_event_enable is no longer available. You should use these nrfx_gpiote_input_configure and nrfx_gpiote_trigger_enable functions instead GPIOTE driver. It's also mentioned here (+) warning: implicit declaration of function 'nrfx_gpiote_in_uninit'; did you mean 'nrfx_gpiote_pin_uninit'? on ncs v2.5.2 - Nordic Q&A - Nordic DevZone - Nordic DevZone

And for the second error, you can not set CONFIG_NRFX_GPIOTE=y in prj.conf in NCS v2.7.0+; use CONFIG_NRFX_GPIOTE0 or CONFIG_NRFX_GPIOTE1 if needed. You can read this case (+) Upgrading ToolChain/SDK from 2.5.2 to 2.7.0 error with GPIOTE - Nordic Q&A - Nordic DevZone - Nordic DevZone
