| Programming and Debugging |
| ************************* |
| |
| 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 board nRF51 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: nrf51_ble400 |
| :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 nRF51 DK |
| ******************************************** |
| |
| There are samples below 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` |
| - :zephyr:code-sample:`fade-led` |
| - :zephyr:code-sample:`multi-thread-blinky` |
| |
| 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/waveshare/nrf51_ble400/nrf51_ble400.dts`. |
