Programming and Debugging

Nucleo WB05KZ board includes an ST-LINK-V3EC embedded debug tool interface.

Applications for the nucleo_w05kz board target can be built and flashed in the usual way (see Building an Application and Run an Application for more details).

Flashing

The board is configured to be flashed using the west STM32CubeProgrammer runner, so it must be installed beforehand.

Alternatively, OpenOCD can also be used to flash the board using the --runner (or -r) option:

$ west flash --runner openocd

Flashing an application to Nucleo WB05KZ

Connect the Nucleo WB05KZ to your host computer using the USB port, then run a serial host program to connect with your Nucleo board:

$ minicom -D /dev/ttyACM0

Now build and flash an application. Here is an example for Hello World.

# From the root of the zephyr repository
west build -b nucleo_wb05kz samples/hello_world
west flash

You should see the following message on the console:

Hello World! nucleo_wb05kz/stm32wb05

Debugging

You can debug an application in the usual way. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b nucleo_wb05kz samples/hello_world
west debug
