| Programming and Debugging |
| ************************* |
| |
| Applications for the ``ubx_evkninab3/nrf52840`` board configuration can be |
| built and flashed in the usual way (see :ref:`build_an_application` |
| and :ref:`application_run` for more details); however, the standard |
| debugging targets are not currently available. |
| |
| 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 <tty_device> -b 115200 |
| |
| Replace :code:`<tty_device>` 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/u-blox/ubx_evkninab3/ubx_evkninab3_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 = <NRF_PSEL(UART_TX, 0, 14)>, |
| <NRF_PSEL(UART_RX, 0, 16)>; |
| }; |
| }; |
| /* required if CONFIG_PM_DEVICE=y */ |
| uart1_sleep: uart1_sleep { |
| group1 { |
| psels = <NRF_PSEL(UART_TX, 0, 14)>, |
| <NRF_PSEL(UART_RX, 0, 16)>; |
| 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 ``<board>.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. |
