See `nRF9161 DK website`_ and `nRF9161 Product Specification`_ for a complete list of nRF9161 DK board hardware features. Connections and IOs =================== LED --- * LED1 (green) = P0.0 * LED2 (green) = P0.1 * LED3 (green) = P0.4 * LED4 (green) = P0.5 Push buttons and Switches ------------------------- * BUTTON1 = P0.8 * BUTTON2 = P0.9 * SWITCH1 = P0.18 * SWITCH2 = P0.19 * BOOT = SW5 = boot/reset Security components =================== - Implementation Defined Attribution Unit (`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. - Secure boot. Programming and Debugging ************************* ``nrf9161dk/nrf9161`` supports the Armv8m Security Extension, and by default boots in the Secure state. Building Secure/Non-Secure Zephyr applications with Arm |reg| TrustZone |reg| ============================================================================= The process requires the following steps: 1. Build the Secure Zephyr application using ``-DBOARD=nrf9161dk/nrf9161`` and ``CONFIG_TRUSTED_EXECUTION_SECURE=y`` in the application project configuration file. 2. Build the Non-Secure Zephyr application using ``-DBOARD=nrf9161dk/nrf9161/ns``. 3. Merge the two binaries together. 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. Building a Secure only application ================================== Build the Zephyr app in the usual way (see :ref:`build_an_application` and :ref:`application_run`), using ``-DBOARD=nrf9161dk/nrf9161``. Flashing ======== 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 -b 115200 Replace :code:`` 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. .. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: nrf9161dk/nrf9161 :goals: build flash Debugging ========= 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: * :zephyr:code-sample:`blinky` * :zephyr:code-sample:`button` You 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`.
