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
