Programming and Debugging
Nucleo WB09KE board includes an ST-LINK-V3EC embedded debug tool interface.
Applications for the nucleo_w09ke 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 WB09KE
Connect the Nucleo WB09KE 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_wb09ke samples/hello_world
west flash
You should see the following message on the console:
Hello World! nucleo_wb09ke/stm32wb09
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_wb09ke samples/hello_world
west debug
