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 :ref:`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 EVK-NINA-B30x 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: ubx_evkninab3_nrf52840 :goals: build flash Debugging ========= Refer to the :ref:`nordic_segger` page to learn about debugging u-blox boards with a Segger J-LINK-OB IC. Testing the LEDs and buttons in the EVK-NINA-B30x ************************************************* There are 2 samples that allow you to test that the buttons (switches) and LEDs on the board are working properly with Zephyr: .. code-block:: console samples/basic/blinky samples/basic/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/arm/ubx_evkninab3_nrf52840/ubx_ninab3_nrf52840.dts`. Using UART1 *********** The following approach can be used when an application needs to use more than one UART for connecting peripheral devices: 1. Add device tree overlay file to the main directory of your application: .. code-block:: devicetree &pinctrl { uart1_default: uart1_default { group1 { psels = , ; }; }; /* required if CONFIG_PM_DEVICE=y */ uart1_sleep: uart1_sleep { group1 { psels = , ; low-power-enable; }; }; }; &uart1 { compatible = "nordic,nrf-uarte"; current-speed = <115200>; status = "okay"; pinctrl-0 = <&uart1_default>; pinctrl-1 = <&uart1_sleep>; pinctrl-names = "default", "sleep"; }; In the overlay file above, pin P0.16 is used for RX and P0.14 is used for TX 2. Use the UART1 as ``DEVICE_DT_GET(DT_NODELABEL(uart1))`` Overlay file naming =================== The file has to be named ``.overlay`` and placed in the app main directory to be picked up automatically by the device tree compiler. Selecting the pins ================== Pins can be configured in the board pinctrl file. To see the available mappings, open the data sheet for the NINA-B3 at `u-blox website`_, Section 3 'Pin definition'. In the table 7 select the pins marked 'GPIO_xx'. Note that pins marked as 'Radio sensitive pin' can only be used in under-10KHz applications. They are not suitable for 115200 speed of UART. .. note: Pins are defined according to the "nRF52" pin number, not the module pad number.
