Programming and Debugging
Applications for the we_proteus3ev/nrf52840 board configuration can be
built, flashed, and debugged in the usual way. See
Building an Application and Run an Application for more details on
building and running.
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 Proteus-III-EV
can be found. For example, under Linux, /dev/ttyACM0.
Then build and flash the application in the usual way.

west flash
Debugging
