How to integrate Zephyr drivers into custom Zephyr app:
^ To Set cmake Options In SES
As of 2021-09-24, using Segger version xxx Nordic's version, this Segger IDE offers an extra menu item to open, build, flash and debug nRF SDK sample apps. The initial dialog box which appears for this option is titled "nRF Connect Options". Just left of the title there is a Nordic colored icon showing two links of chain, white on blue.
There are five input boxes, a mix of text inputs and drop down menus, and two sets of radio buttons. The free form text input box titled "Extra CMake Build Options" is a key place to express custom configuration settings to `cmake`. To use, for example, Zephyr's latest stable arm cross compiling toolchain in place of Nordic's close but not quite as recent chosen release of GNU ARM cross compiler toolchain, the following `cmake` option needs be entered here:
-DZEPHYR_TOOLCHAIN_VARIANT=zephyr
The default value for 'ZEPHYR_TOOLCHAIN_VARIANT' with Nordic's SDK v1.6.1 is 'gnuarmemb'. It is not sufficient to set a variable by this name in the shell environment of Linux systems, nor is it sufficient to set a Segger global or project macro by this name equal to the string "zephyr". This change in toolchain name or branding must be passed to `cmake` on its command line. In Segger, we build with a button press, so the command line option is only accessible to us from certain limited place or places. This text input box is our place to express needed custom command line options to `cmake` when working within SES.

Hello CircuitDojo Community,
In a [recent post](https://community.jaredwolff.com/d/222-nrf9160-sleep-and-low-power-control-areas/2) I inquired about low power configurations for the nRF9160 and boards based on this SiP. Jared Wolff shared code which dynamically turns off a given UART of the SiP's application processor. In his code there's a call to a routine named `uart_rx_disable().` I'd initially overlooked this. Today as I try to build my application I'm blocked on a link time error "undefined reference to `'".
Per Jared's code excerpt I have added `CONFIG_PM_DEVICE=y` to my prj.conf. My project is based on Nordic's aws_iot sample app. I am using the ncs SDK version 1.6.1. Nordic's fork of Zephyr in this SDK is Zephyr release 2.6.0.
Where should `uart_rx_disable()` be defined? Am I using a too old version of ncs or Zephyr RTOS?
