Board pinout
The LAUNCHXL-CC1352R1 Quick Start Guide provides the default pinout for the board.
Flashing the Device
Flashing RIOT is quite straight forward. The board comes with an XDS110 on-board debug probe that provides programming, flashing and debugging capabilities through the USB Micro-USB connector. Once either TI Uniflash or OpenOCD are installed just connect the board using the Micro-USB port to your computer and type:
make flash BOARD=cc1352-launchpad
To use OpenOCD instead of uniflash we need to set the PROGRAMMER environment
variable, this is to enable OpenOCD instead of Uniflash.
export PROGRAMMER=openocd
Now we can just do make flash and make debug, this all using OpenOCD.
Accessing RIOT shell
Default RIOT shell access utilize XDS110 debug probe integrated with launchpad board. It provides virtual serials via USB interface - for connecting to RIOT shell, use the first one.
If a physical connection to UART is needed, disconnect jumpers RXD and TXD joining cc1352 microcontroller with XDS110 and connect UART to pin RXD/DIO12 and TXD/DIO13.
The default baud rate is 115 200 - in both connection types.
@warning Launchpad cc1352 board is not 5V tolerant. Use voltage divider or logic level shifter when connecting to 5V UART.
