CC1352P7 LaunchPad
Overview
The Texas Instruments CC1352P7 LaunchPad™ (LP-CC1352P7) is a development kit for the SimpleLink™ multi-Standard CC1352P7 wireless MCU.
See the TI CC1352P7 LaunchPad Product Page for details.
Hardware
The CC1352P7 LaunchPad™ development kit features the CC1352P7 wireless MCU. The board is equipped with two LEDs, two push buttons, antenna switch and BoosterPack connectors for expansion. It also includes an integrated (XDS110) debugger.
The CC1352P7 wireless MCU has a 48 MHz Arm® Cortex®-M4F SoC and an integrated sub-1GHz and 2.4 GHz transceiver with integrated 20dBm power amplifier (PA) supporting multiple protocols including Bluetooth® Low Energy and IEEE® 802.15.4.
See the TI CC1352P7 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 TXD and RXD signals for a serial console using the XDS110 application serial port.
Prerequisites:
Ensure the XDS-110 emulation firmware on the board is updated.
Download and install the latest XDS-110 emulation package.
Follow these xds110 firmware update directions
Note that the emulation package install may place the xdsdfu utility in
<install_dir>/ccs_base/common/uscif/xds110/.Install OpenOCD
Currently, OpenOCD doesn’t support the CC1352P7. Until its support get merged, we have to builld a downstream version that could found here. Please refer to OpenOCD documentation to build and install OpenOCD.
For your convenience, we provide a prebuilt binary.
$ unzip openocd-810cb5b21-x86_64-linux-gnu.zip
$ chmod +x openocd-x86_64-linux-gnu/bin/openocd
$ export OPENOCD_DIST=$PWD/openocd-x86_64-linux-gnu
By default, zephyr will try to use the OpenOCD binary from SDK.
You will have to define OPENOCD and OPENOCD_DEFAULT_PATH to use the custom OpenOCD binary.
Flashing
Applications for the CC1352P7 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 cc1352p7_lp samples/hello_world -- -DOPENOCD=$OPENOCD_DIST/bin/openocd -DOPENOCD_DEFAULT_PATH=$OPENOCD_DIST/share/openocd
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 cc1352p7_lp samples/hello_world -- -DOPENOCD=$OPENOCD_DIST/bin/openocd -DOPENOCD_DEFAULT_PATH=$OPENOCD_DIST/share/openocd
west debug
Bootloader
The ROM bootloader on CC13x2x7 and CC26x2x7 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
CC13x2x7 / CC26x2x7 Technical Reference Manual for additional information.
Power Management and UART
System and device power management are supported on this platform, and
can be enabled via the standard Kconfig options in Zephyr, such as
CONFIG_PM, CONFIG_PM_DEVICE.
When system power management is turned on (CONFIG_PM=y), sleep state 2 (standby mode) is allowed, and polling is used to retrieve input by calling uart_poll_in(), it is possible for characters to be missed if the system enters standby mode between calls to uart_poll_in(). This is because the UART is inactive while the system is in standby mode. The workaround is to disable sleep state 2 while polling:
pm_policy_state_lock_get(PM_STATE_STANDBY, PM_ALL_SUBSTATES);
<code that calls uart_poll_in() and expects input at any point in time>
pm_policy_state_lock_put(PM_STATE_STANDBY, PM_ALL_SUBSTATES);
