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 board nRF52 DK
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: nrf52dk/nrf52832
   :goals: build flash

Debugging
=========

Refer to the :ref:`nordic_segger` page to learn about debugging Nordic boards with a
Segger IC.


Testing the LEDs and buttons in the nRF52 DK
********************************************

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/nordic/nrf52dk/nrf52dk_nrf52832.dts`.

Overview

The ``nrf52dk/nrf52805`` board is a modified version of the :ref:`nrf52dk_nrf52832`
that enforces the limitations imposed by the nRF52805 IC, which is a
cost-reduced variant of the original nRF52832. Since Nordic does not offer a
development kit for the nRF52805, you can use this board to develop for this
IC while using the nRF52 Development Kit (PCA10040).

See :ref:`nrf52dk_nrf52832` for more information about the development board and

프로그래밍과 디버깅

Flash

Nordic Segger 안내에 따라 필요한 소프트웨어를 설치하고 구성한 뒤 일반적인 방식으로 애플리케이션을 빌드하고 flash합니다. 다음은 hello_world 예입니다.

먼저 원하는 terminal 프로그램으로 출력을 수신합니다.

$ minicom -D <tty_device> -b 115200

<tty_device>는 nRF52 DK가 연결된 port로 바꾸십시오. Linux에서는 예를 들어 /dev/ttyACM0입니다.

# From the root of the zephyr repository
west build -b nrf52dk/nrf52832 samples/hello_world
west flash

Debug

Segger IC를 이용한 Nordic 보드 디버깅 방법은 Nordic Segger 문서를 참고하십시오.

LED와 버튼 시험

다음 두 sample로 버튼(switch)과 LED가 Zephyr에서 올바르게 동작하는지 시험할 수 있습니다.

samples/basic/blinky
samples/basic/button

예제를 빌드하고 flash하면 보드에서 Zephyr가 정상 실행되는지 확인할 수 있습니다. 버튼과 LED 정의는 boards/nordic/nrf52dk/nrf52dk_nrf52832.dts에 있습니다.

nRF52 DK에서 nRF52805 에뮬레이션

nrf52dk/nrf52805 보드는 원래 nrf52dk/nrf52832을 수정해 nRF52832의 비용 절감형 변형인 nRF52805 IC의 제한을 강제한 대상입니다.

Nordic은 nRF52805용 개발 키트를 제공하지 않으므로 nRF52 Development Kit(PCA10040)를 사용하면서 이 대상으로 nRF52805용 소프트웨어를 개발할 수 있습니다. 개발 보드는 앞의 nRF52 DK 설명을, IC 자체의 공식 정보는 nRF52805 웹사이트를 참고하십시오.

nRF52 DK에서 nRF52810 에뮬레이션

nrf52dk/nrf52810 보드는 원래 nrf52dk/nrf52832을 수정해 nRF52832의 비용 절감형 변형인 nRF52810 IC의 제한을 강제한 대상입니다.

Nordic은 nRF52810용 개발 키트를 제공하지 않으므로 nRF52 Development Kit(PCA10040)를 사용하면서 이 대상으로 nRF52810용 소프트웨어를 개발할 수 있습니다. 개발 보드는 앞의 nRF52 DK 설명을, IC 자체의 공식 정보는 nRF52810 웹사이트를 참고하십시오.
