Note

The BMD-330-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-330-EVAL and the BMD-330 module can be found at the u-blox website [1]. All of the Nordic Semiconductor examples for the nRF52 DK (nrf52dk_nrf52810) may be used without modification.

Hardware

The BMD-330 on the BMD-330-EVAL contains an internal high-frequency oscillator at 32MHz. There is also a low frequency (slow) oscillator of 32.768kHz. The BMD-330 itself does not include the slow crystal; however, the BMD-330-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 Nordic nRF5x Segger J-Link page to install and configure all the necessary software. Further information can be found in Flashing. Then build and flash applications as usual (see Building an Application and Run an Application for more details).

Here is an example for the Hello World application.

First, run your favorite terminal program to listen for output.

$ minicom -D <tty_device> -b 115200

Replace <tty_device> with the port where the BMD-330-EVAL can be found. For example, under Linux, /dev/ttyACM0.

Then build and flash the application in the usual way.

# From the root of the zephyr repository
west build -b ubx_bmd330eval/nrf52810 samples/hello_world
west flash

Debugging

Refer to the Nordic nRF5x Segger J-Link 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:

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 boards/u-blox/ubx_bmd330eval/ubx_bmd330eval_nrf52810.dts.
