+
+Hardware
+********
+
+The CC1352R LaunchPad |trade| development kit features the CC1352R wireless MCU.
+The board is equipped with two LEDs, two push buttons and BoosterPack connectors
+for expansion. It also includes an integrated (XDS110) debugger.
+
+The CC13522 wireless MCU has a 48 MHz Arm |reg| Cortex |reg|-M4F SoC and an
+integrated Sub-1 and 2.4 GHz transceiver supporting multiple protocols including
+Bluetooth |reg| Low Energy and IEEE |reg| 802.15.4.
+
+See the `TI CC1352R Product Page`_ for additional details.

+Programming and Debugging
+*************************
+
+Before flashing or debugging ensure the RESET, TMS, TCK, TDO, and TDI jumpers
+are in place. Also place jumpers on the the TXD and RXD signals for a serial
+console using the XDS110 application serial port.
+
+Flashing
+========
+
+Applications for the ``CC1352R LaunchPad`` board configuration can be built and
+flashed in the usual way (see :ref:`build_an_application` and
+:ref:`application_run` for more details).
+
+Here is an example for the :ref:`hello_world` application.
+
+First, run your favorite terminal program to listen for output.
+
+.. code-block:: console
+
+   $ screen <tty_device> 115200
+
+Replace :code:`<tty_device>` with the port where the XDS110 application
+serial device can be found. For example, :code:`/dev/ttyACM0`.
+
+Then build and flash the application in the usual way.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: cc1352r1_launchxl
+   :goals: build flash
+
+Debugging
+=========
+
+You can debug an application in the usual way.  Here is an example for the
+:ref:`hello_world` application.

+   :maybe-skip-config:
