Overview
The nRF9161 DK (PCA10153) is a single-board development kit for evaluation and
development on the nRF9161 SiP for DECT NR+ and LTE-M/NB-IoT with GNSS. The nrf9161dk/nrf9161
board configuration provides support for the Nordic Semiconductor nRF9161 ARM
Cortex-M33F CPU with ARMv8-M Security Extension.
More information about the board can be found at the
nRF9161 DK website. nRF9161 Product Specification
contains the processor's information and the datasheet.
Hardware
nRF9161 DK has two external oscillators. The frequency of the slow clock is 32.768 kHz. The frequency of the main clock is 32 MHz.

IDAU_). The IDAU is implemented
with the System Protection Unit and is used to define secure and non-secure
memory maps. By default, all of the memory space (Flash, SRAM, and
peripheral address space) is defined to be secure accessible only.Programming and Debugging

nrf9161dk/nrf9161 supports the Armv8m Security Extension, and by default boots
in the Secure state.
The process requires the following steps:
-DBOARD=nrf9161dk/nrf9161 and
CONFIG_TRUSTED_EXECUTION_SECURE=y in the application project configuration file.-DBOARD=nrf9161dk/nrf9161/ns.When building a Secure/Non-Secure application, the Secure application will have to set the IDAU (SPU) configuration to allow Non-Secure access to all CPU resources utilized by the Non-Secure application firmware. SPU configuration shall take place before jumping to the Non-Secure application.
Build the Zephyr app in the usual way (see :ref:build_an_application
and :ref:application_run), using -DBOARD=nrf9161dk/nrf9161.
Follow the instructions in the :ref:nordic_segger page to install
and configure all the necessary software. Further information can be
found in :ref:nordic_segger_flashing. Then build and flash
applications as usual (see :ref:build_an_application and
:ref:application_run for more details).
Here is an example for the :zephyr:code-sample:hello_world application.
First, run your favorite terminal program to listen for output.
.. code-block:: console
$ minicom -D <tty_device> -b 115200
Replace :code:<tty_device> with the port where the nRF9161 DK
can be found. For example, under Linux, :code:/dev/ttyACM0.
Then build and flash the application in the usual way.

Refer to the :ref:nordic_segger page to learn about debugging Nordic boards with a
Segger IC.
Testing the LEDs and buttons in the nRF9161 DK
There are 2 samples that allow you to test that the buttons (switches) and LEDs on the board are working properly with Zephyr:
blinkybuttonYou can build and flash the examples to make sure Zephyr is running correctly on
your board. The button and LED definitions can be found in
:zephyr_file:boards/nordic/nrf9161dk/nrf9161dk_nrf9161_common.dtsi.
