|
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)`
|
|
* RADIO (Bluetooth Low Energy)
|
|
* :abbr:`RTC (nRF RTC System Clock)`
|
|
* Segger RTT (RTT Console)
|
|
* :abbr:`SPI (Serial Peripheral Interface)`
|
|
* :abbr:`UART (Universal asynchronous receiver-transmitter)`
|

.. 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 :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
|
|
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/u-blox/ubx_bmd360eval/ubx_bmd360eval_nrf52811.dts`.
