96Other hardware features are not yet supported in this Zephyr port.
97
98The default configuration can be found in
99:zephyr_file:`boards/st/nucleo_f103rb/nucleo_f103rb_defconfig`
100
101Connections and IOs
102===================
103
104Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as
105input (with or without pull-up or pull-down), or as peripheral alternate function. Most of the
106GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current
107capable except for analog inputs.

129Programming and Debugging
130*************************
131
132Nucleo F103RB board includes an ST-LINK/V2-1 embedded debug tool interface.
133
134Applications for the ``nucleo_f103rb`` board configuration can be built and
135flashed in the usual way (see :ref:`build_an_application` and
136:ref:`application_run` for more details).
137
138Flashing
139========
140
141The board is configured to be flashed using west `STM32CubeProgrammer`_ runner,
142so its :ref:`installation <stm32cubeprog-flash-host-tools>` is required.
143
144Alternatively, OpenOCD or JLink can also be used to flash the board using
145the ``--runner`` (or ``-r``) option:
146
147.. code-block:: console
148
149   $ west flash --runner openocd
150   $ west flash --runner jlink
151
152Flashing an application to Nucleo F103RB
153----------------------------------------
154
155Here is an example for the :zephyr:code-sample:`blinky` application.
156
157.. zephyr-app-commands::
158   :zephyr-app: samples/basic/blinky
159   :board: nucleo_f103rb
160   :goals: build flash
161
162You will see the LED blinking every second.
163
164Debugging
165=========
166
167You can debug an application in the usual way.  Here is an example for the
168:zephyr:code-sample:`blinky` application.
169
170.. zephyr-app-commands::
171   :zephyr-app: samples/basic/blinky
172   :board: nucleo_f103rb
173   :maybe-skip-config:
174   :goals: debug
