| 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 :ref:`hello_world` application. |
| |
| First, run your favorite terminal program to listen for output. |
| |
| NOTE: On the BL652 DVK, the FTDI USB should be used to access the UART console. |
| |
| .. code-block:: console |
| |
| $ minicom -D <tty_device> -b 115200 |
| |
| Replace :code:`<tty_device>` with the port where the BL652 DVK |
| can be found. For example, under Linux, :code:`/dev/ttyUSB0`. |
| |
| Then build and flash the application in the usual way. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: bl652_dvk |
| :goals: build flash |
| |
| Debugging |
| ========= |
| |
| Refer to the :ref:`nordic_segger` page to learn about debugging Nordic based boards with a |
| Segger IC. |
| |
| Testing Bluetooth on the BL652 DVK |
| ********************************** |
| Many of the Bluetooth examples will work on the BL652 DVK. |
| Try them out: |
| |
| * :ref:`ble_peripheral` |
| * :ref:`bluetooth-eddystone-sample` |
| * :ref:`bluetooth-ibeacon-sample` |
| |
| Testing the LEDs and buttons in the BL652 DVK |
| ********************************************* |
| |
| There are 2 samples that allow you to test that the buttons (switches) and LEDs on |
| the board are working properly with Zephyr: |
| |
| * :ref:`blinky-sample` |
| * :ref:`button-sample` |
| |
| 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/bl652_dvk/bl652_dvk.dts`. |
