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.
$ 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.
Then build and flash the application in the usual way.
# From the root of the zephyr repository
west build -b nrf52dk/nrf52832 samples/hello_world
west flash
Debugging
Refer to the Nordic nRF5x Segger J-Link page to learn about debugging Nordic boards with a Segger IC.

nRF52805 emulation on nRF52 DK
Overview
The nrf52dk/nrf52805 board is a modified version of the nRF52 DK
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 nRF52 DK for more information about the development board and nRF52805 website [11] [7] [3] for the official reference on the IC itself.
