| Programming and Debugging |
| ************************* |
| |
| .. zephyr:board-supported-runners:: |
| |
| 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 nRF52 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: nrf52dk/nrf52832 |
| :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 nRF52 DK |
| ******************************************** |
| |
| 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/nordic/nrf52dk/nrf52dk_nrf52832.dts`. |
| |
| .. _nrf52dk_nrf52805: |
| |
| nRF52805 emulation on nRF52 DK |
| ****************************** |
| |
| The ``nrf52dk/nrf52805`` board is a modified version of the :zephyr:board:`nrf52dk` |
| that enforces the limitations imposed by the nRF52805 IC, which is a |
| cost-reduced variant of the original nRF52832. Since Nordic does not offer a |
| development kit for the nRF52805, you can use this board to develop for this |
| IC while using the nRF52 Development Kit (PCA10040). |
| |
| See `nRF52805 website`_ for the official reference on the IC itself. |
| |
| .. _nrf52dk_nrf52810: |
| |
| nRF52810 emulation on nRF52 DK |
| ****************************** |
| |
| The ``nrf52dk/nrf52810`` board variant is a modified version of the :zephyr:board:`nrf52dk` |
| that enforces the limitations imposed by the nRF52810 IC, which is a |
| cost-reduced variant of the original nRF52832. Since Nordic does not offer a |
| development kit for the nRF52810 you can use this board to develop for this |
| IC while using the nRF52 Development Kit (PCA10040). |
| |
| See `nRF52810 website`_ for the official reference on the IC itself. |
