| ############## |
| |
| 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. |
| |
| #. 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. |
