Hardware
********

The CC26x2R LaunchPad |trade| development kit features the CC2652R 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 CC2652 wireless MCU has a 48 MHz Arm |reg| Cortex |reg|-M4F SoC and an
integrated 2.4 GHz transceiver supporting multiple protocols including Bluetooth
|reg| Low Energy and IEEE |reg| 802.15.4.

See the `TI CC2652R 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 ``CC26x2R 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: cc26x2r1_launchxl
:goals: build flash

Debugging
=========

You can debug an application in the usual way. Here is an example for the
:ref:`hello_world` application.

.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: cc26x2r1_launchxl
:maybe-skip-config:
:goals: debug
