.. _ubx_bmd300eval_nrf52832: u-blox EVK-BMD-30/35: BMD-300-EVAL, BMD-301-EVAL, and BMD-350-EVAL ################################################################## Overview ******** The BMD-300-EVAL, BMD-301-EVAL, and BMD-350-EVAL hardware provides support for the u-blox BMD-300, BMD-301, and BMD-350 Bluetooth 5 modules, based on the Nordic Semiconductor nRF52832 ARM Cortex-M4F 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)` * :abbr:`WDT (Watchdog Timer)` .. figure:: ../../../../../../../../../zephyr/boards/arm/ubx_bmd300eval_nrf52832/doc/img/BMD-30-33-35-36-EVAL.jpg :align: center :alt: BMD-300-EVAL BMD-300-EVAL (Credit: u-blox AG) .. note:: The BMD-300-EVAL, BMD-301-EVAL, and BMD-350-EVAL share the same pin headers and assignments. The boards are different only in the module used on the board. The BMD-300 and BMD-301 modules share the same footprint and differ only in the antenna. The BMD-350 module utilizes the nRF52832 CIAA WLCSP package. More information about the BMD-300-EVAL, BMD-301-EVAL, and BMD-350-EVAL and the respective modules can be found at the `u-blox website`_. All of the Nordic Semiconductor examples for the nRF52 DK (nrf52dk_nrf52832) may be used without modification. Hardware ******** The BMD-300/301/350 module on the board contains an internal high-frequency oscillator at 32MHz. There is also a low frequency (slow) oscillator of 32.768kHz. The module itself does not include the slow crystal; however, the EVAL boards do. .. 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.

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 -b 115200 Replace :code:`` with the port where the BMD-300/301/350-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_bmd300eval_nrf52832 :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-330-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_bmd300eval_nrf52832/ubx_bmd300eval_nrf52832.dts`.
