Programming and Debugging
Applications for the we_proteus2ev_nrf52832 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-II-EV
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 we_proteus2ev_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.
Testing the LEDs and buttons in the Proteus-II-EV
There are 2 samples that allow you to test that the buttons (switches) and LEDs on the board are working properly with Zephyr:
samples/basic/blinky
samples/basic/button
You can build and flash the examples to make sure Zephyr is running correctly on your board. The button and LED definitions can be found in boards/arm/nrf52dk_nrf52832/nrf52dk_nrf52832.dts.
