  • CPU core: ARM Cortex®-M33 with FPU
  • Flash memory: 1024 kB
  • RAM: 256 kB
  • Transmit power: up to +8 dBm
  • Operation frequency: 2.4 GHz
  • Crystal oscillators for LFXO (32.768 kHz) and HFXO (38.4 MHz)

Supported Features

Programming and Debugging

.. zephyr:board-supported-runners::

Applications for the xg29_rb4412a board target can be built, flashed, and debugged in the usual way. See :ref:build_an_application and :ref:application_run for more details on building and running.

Flashing

As an example, this section shows how to build and flash the :zephyr:code-sample: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:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: xg29_rb4412a :goals: build 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:

.. code-block:: console

Hello World! xg29_rb4412a

Bluetooth

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

.. code-block:: console

west blobs fetch hal_silabs

Then build the Zephyr kernel and a Bluetooth sample with the following command. The :zephyr:code-sample:bluetooth_observer sample application is used in this example.

.. zephyr-app-commands:: :zephyr-app: samples/bluetooth/observer :board: xg29_rb4412a :goals: build
