Hardware

The CC1352R LaunchPad™ 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® Cortex®-M4F SoC and an integrated Sub-1 and 2.4 GHz transceiver supporting multiple protocols including Bluetooth® Low Energy and IEEE® 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 Building an Application and Run an Application for more details).

Here is an example for the Hello World application.

First, run your favorite terminal program to listen for output.

$ screen <tty_device> 115200

Replace <tty_device> with the port where the XDS110 application serial device can be found. For example, /dev/ttyACM0.

Then build and flash the application in the usual way.

# From the root of the zephyr repository
west build -b cc1352r1_launchxl samples/hello_world
west flash

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 cc1352r1_launchxl samples/hello_world
west debug

Bootloader

The ROM bootloader on CC13x2 and CC26x2 devices is enabled by default. The bootloader will start if there is no valid application image in flash or the so-called backdoor is enabled (via option CONFIG_CC13X2_CC26X2_BOOTLOADER_BACKDOOR_ENABLE) and BTN-1 is held down during reset. See the bootloader documentation in chapter 10 of the TI CC13x2 / CC26x2 Technical Reference Manual for additional information.
