nRF52-PCA10040
##############
Overview
********
Zephyr applications use the nrf52_pca10040 board configuration
to run on the nRF52 Development Kit (PCA10040) hardware. It provides
support for the Nordic Semiconductor nRF52832 ARM Cortex-M4F CPU and
the following devices:
* :abbr:`NVIC (Nested Vectored Interrupt Controller)`
* :abbr:`SYSTICK (System Tick System Clock)`
* UART
* GPIO
More information about the board can be found at the
`nRF52 DK website`_. The `Nordic Semiconductor Infocenter`_
contains the processor's information and the datasheet.

System Clock
************
nRF52 DK has two external oscillators. The frequency of
the slow clock is 32.768 kHz. The frequency of the main clock
is 32 MHz.
Flashing Zephyr onto nRF52 DK
*****************************
Flashing the Zephyr kernel onto nRF52 DK requires both the
`J-Link Software and documentation pack`_ and, the nrfjprog tool,
which is part of the nRF5x Command Line Tools.
Installing the J-Link Software and documentation pack
=====================================================
To install the J-Link Software and documentation pack, follow the
steps below:
#. Download the appropriate package from the
`J-Link Software and documentation pack`_ website.
#. Depending on your platform, install the package
or run the installer
#. When connecting a J-Link-enabled device such as the
nRF52 DK board, a drive corresponding to a USB Mass Storage device
as well as a serial port should come up.
Installing the nRF5x Command Line Tools
=======================================
To install the nRF5x Command Line Tools, follow the steps below:
#. Download the appropriate package from the `nRF52 DK website`_.
#. Depending on your platform, unpack the tarball and copy the
contents into a folder whithin your $PATH or run the installer.
Flashing an Application to nRF52 DK
===================================
This tutorial uses the sample application
shell :file:`$ZEPHYR_BASE/samples/shell`.
#. To build the Zephyr kernel, enter:
.. code-block:: console
$ cd $ZEPHYR_BASE
$ make -C samples/shell BOARD=nrf52_pca10040
#. Connect the micro-USB cable to the nRF52 DK and to your computer.
#. Convert the Zephyr kernel image to Intel Hex:
.. code-block:: console
$ cd samples/shell
$ objcopy -O ihex outdir/zephyr.elf outdir/zephyr.hex
The :code:`objcopy` binary must be the one included with the
toolchain you used to build the Zephyr kernel
#. Erase the flash memory in the nRF52832:
.. code-block:: console
$ nrfjprog --eraseall -f nrf52
#. Flash the application using the nrfjprog tool:
.. code-block:: console
$ nrfjprog --program outdir/zephyr.hex -f nrf52
#. 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`.
The :option:`-b` option sets baudrate ignoring the value
from config.
#. Press the Reset button and you should see the output of
shell application in your terminal.
