| ################################ |
| |
| Overview |
| ******** |
| |
| The BMD-360-EVAL hardware provides support for the |
| u-blox BMD-360 Bluetooth 5 module, based on The |
| Nordic Semiconductor nRF52811 ARM Cortex-M4 CPU and |
| the following devices: |
| |
| * :abbr:`ADC (Analog to Digital Converter)` |
| * CLOCK |
| * FLASH |
| * :abbr:`GPIO (General Purpose Input Output)` |
| * :abbr:`I2C (Inter-Integrated Circuit)` |
| * :abbr:`MPU (Memory Protection Unit)` |
| * :abbr:`NVIC (Nested Vectored Interrupt Controller)` |
| * :abbr:`PWM (Pulse Width Modulation)` |

| .. note:: |
| The BMD-360-EVAL shares the same pin headers and assignments as the |
| BMD-300-EVAL. The BMD-300-EVAL is shown here. |
| |
| More information about the BMD-360-EVAL and the BMD-360 module |
| can be found at the `u-blox website`_. |
| |
| Hardware |
| ******** |
| |
| The BMD-360 on the BMD-360-EVAL contains an internal |
| high-frequency oscillator at 32MHz. There is also a low frequency |
| (slow) oscillator of 32.768kHz. The BMD-360 itself does not include |
| the slow crystal; however, the BMD-360-EVAL does. |
| |
| .. note:: |
| When targeting a custom design without a slow crystal, |
| be sure to modify code to utilize the internal RC |
| oscillator for the slow clock. |
| |

| 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. |
| |
| .. code-block:: console |
| |
| $ minicom -D <tty_device> -b 115200 |
| |
| Replace :code:`<tty_device>` with the port where the |
| BMD-360-EVAL 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_bmd360eval_nrf52811 |
| :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 BMD-360-EVAL |
| ************************************************ |
| |
| 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_bmd360eval_nrf52811/ubx_bmd360eval_nrf52811.dts`. |
