Programming and Debugging

The xg29_rb4412a board supports the runners and associated west commands listed below.

	flash	debug	attach	rtt	debugserver
jlink	✅ (default)	✅ (default)	✅	✅	✅
silabs_commander	✅

Applications for the xg29_rb4412a board target can be built, flashed, and debugged in the usual way. See Building an Application and Run an Application for more details on building and running.

Flashing

As an example, this section shows how to build and flash the Hello World application.

To build and program the sample to the xG24-RB4412A, complete the following steps:

First, plug the xG24-RB4412A to a compatible mainboard and connect the mainboard to your computer using the USB port on the left side. Next, build and flash the sample by running the following command:

# From the root of the zephyr repository
west build -b xg29_rb4412a samples/hello_world
west flash

west flash will by default use SEGGER JLink. Make sure that the JLinkExe binary is available on the PATH. Alternatively, use west flash -r silabs_commander to use Simplicity Commander to flash. In this case, make sure that the commander binary is available on PATH.

Open a serial terminal (minicom, putty, etc.) with the following settings:

• Speed: 115200

• Data: 8 bits

• Parity: None

• Stop bits: 1

Reset the board and you should see the following message in the terminal:

Hello World! xg29_rb4412a

Bluetooth

To use the BLE function, run the command below to retrieve necessary binary blobs from the SiLabs HAL repository.

west blobs fetch hal_silabs

Then build the Zephyr kernel and a Bluetooth sample with the following command. The Observer sample application is used in this example.

# From the root of the zephyr repository
west build -b xg29_rb4412a samples/bluetooth/observer
