Programming and Debugging
Applications for the we_oceanus1ev board can be built the
usual way (see Building an Application).
The board debugged and flashed with an external debug probe connected to the SWD pins, current native support is for the JLink debug probe.
Flashing
Connect the board to your host computer and build and flash an application.
# From the root of the zephyr repository
west build -b we_oceanus1ev samples/hello_world
west flash
Run a serial terminal to connect with your board. By default, lpuart1 is
accessible via the on-board FTDI USB to UART converter.
Debugging
You can debug an application in the usual way. Here is an example for the Blinky application.
# From the root of the zephyr repository
west build -b we_oceanus1ev samples/basic/blinky
west debug
