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.

NOTE: On the BL652 DVK, the FTDI USB should be used to access the UART console.

$ minicom -D <tty_device> -b 115200

Replace <tty_device> with the port where the BL652 DVK can be found. For example, under Linux, /dev/ttyUSB0.

Then build and flash the application in the usual way.

# From the root of the zephyr repository
west build -b bl652_dvk samples/hello_world
west flash

Debugging

Refer to the Nordic nRF5x Segger J-Link 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:

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:

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/ezurio/bl652_dvk/bl652_dvk.dts.
