How to Build and Flash the Matter Accessory Device (MAD)#

The Matter Accessory Device, such as the lighting-app, is the actual Matter device that you will commission onto the Matter network and control using the chip-tool.

Step 1: Get the Image File to Flash the MAD#

We have provided three ways to get the required image to flash the MAD. You can use one of the following options:

  1. Use the pre-built image file available in both [SIMPLICITY STUDIO] & [GITHUB]

  2. Build the image file from the 'matter' repository

  3. Build the image file from within Simplicity Studio using the Silicon Labs Matter GSDK Extension

    IMPORTANT: A complete list of software requirements for Silicon Labs Matter 15.4 development is included on the Matter Software Requirements page. Be sure that you have satisfied these requirements before proceeding.

  • Using the Pre-Built Image File#


    All of the Matter Accessory Device image files are accessible through the Matter Artifacts Page. If you are using a pre-built image file, you can skip forward to Step #2: Flashing the MAD.


    All of the pre-built Matter Accessory Device (MAD) image files are available inside Simplicity Studio as Matter Demos. Once you have loaded the Matter Extension to the Gecko SDK (GSDK) you can access all of the associated pre-built image files. For more information on using Simplicity Studio Demos please look at the Simplicity Studio User's Guide

  • Building the Matter Image File from the Repository#


    The Matter Accessory Device (lighting-app) can be built out of the Silicon Labs Matter Github repo.

    Documentation on how to build and use the lighting-app Matter Accessory Device is provided in the Silicon Labs Matter Github Repo under /examples/lighting-app/efr32

    Please note that you only need to build a single device for the demo such as the lighting-app. If you wish to build other examples such as the sleepy end device you are welcome to, but it is not necessary for the demo.

    Additional examples are provided in /examples directory, or /silabs_examples (such as onoff-plug-app).

    The build process puts all image files in the following location:

    <git location>/matter/out/<app name>/<board name>

  • Building the Matter Image File from within Simplicity Studio#


    Silicon Labs offers a complete IDE and Matter Development tool set inside Simplicity Studio. For more information on using Simplicity Studio to build your Matter Accessory Device please consider the Matter in Simplicity Studio section in this documentation.

Step 2: Flash the Matter Accessory Device#


For more information on how to flash your Silabs development platform see the following instructions: How to Flash a Silicon Labs Device

Once your Matter Accessory Device has been flashed it should show a QR code on the LCD. If no QR Code is present it may be that you need to add a bootloader to your device. Bootloader images are provided on the Matter Artifacts page.
