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:
More information about the board can be found at the nRF52 DK website [1]. The Nordic Semiconductor Infocenter [2] contains the processor’s information and the datasheet.
The nrf52_pca10040 board configuration supports the following hardware features:
| Interface | Controller | Driver/Component |
|---|---|---|
| NVIC | on-chip | nested vectored interrupt controller |
| SYSTICK | on-chip | system clock |
| UART | on-chip | serial port |
| GPIO | on-chip | gpio |
Other hardware features are not supported by the Zephyr kernel. See nRF52 DK website [1] and Nordic Semiconductor Infocenter [2] for a complete list of nRF52 Development Kit board hardware features.

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 the Zephyr kernel onto nRF52 DK requires both the J-Link Software and documentation pack[3] and, the nrfjprog tool, which is part of the nRF5x Command Line Tools.
To install the J-Link Software and documentation pack, follow the steps below:
To install the nRF5x Command Line Tools, follow the steps below:
This tutorial uses the sample application shell $ZEPHYR_BASE/samples/shell.
To build the Zephyr kernel, enter:
$ 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:
$ nrfjprog --eraseall -f nrf52
Flash the application using the nrfjprog tool:
$ nrfjprog --program outdir/zephyr.hex -f nrf52
Run your favorite terminal program to listen for output.
$ minicom -D <tty_device> -b 115200
Replace <tty_device> with the port where the board nRF52 DK can be found. For example, under Linux, /dev/ttyACM0.
The -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.
