+
+Programming and Debugging
+*************************
+
+STM32U083C_DK board includes an ST-LINK/V3 embedded debug tool interface.
+This probe allows to flash the board using various tools.
+
+Flashing
+========
+
+Board is configured to be flashed using west STM32CubeProgrammer runner.
+Installation of `STM32CubeProgrammer`_ is then required to flash the board.
+
+Alternatively, pyocd or jlink via an external probe can also be used to flash
+and debug the board if west is told to use it as runner, which can be done by
+passing either or ``-r pyocd``, or ``-r jlink``.
+
+For pyocd additional target information needs to be installed.
+This can be done by executing the following commands.
+
+.. code-block:: console
+
+   $ pyocd pack --update
+   $ pyocd pack --install stm32u0
+
+
+Flashing an application to STM32U083C_DK
+------------------------------------------
+
+Connect the STM32U083C_DK to your host computer using the USB port.
+Then build and flash an application. Here is an example for the
+:ref:`hello_world` application.
+
+Run a serial host program to connect with your Nucleo board:
+
+.. code-block:: console
+
+   $ minicom -D /dev/ttyACM0
+
+Then build and flash the application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: stm32u083c_dk
+   :goals: build flash
+
+You should see the following message on the console:
+
+.. code-block:: console
+
+   Hello World! stm32u083c_dk/stm32u083xx
+
+Debugging
+=========
+
+Default flasher for this board is openocd. It could be used in the usual way.
+Here is an example for the :zephyr:code-sample:`blinky` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/basic/blinky
+   :board: nucleo_u083rc
+   :goals: debug
+
+Note: Check the ``build/tfm`` directory to ensure that the commands required by these scripts
+(``readlink``, etc.) are available on your system. Please also check ``STM32_Programmer_CLI``
+(which is used for initialization) is available in the PATH.
