• Ozone debugging support is enabled for SiWx917 Dual flash boards only.

• For Common Flash Boards Ozone debugging support is not enabled.

• Auto detection of SiWx917 SoC device in Ozone is not enabled.

• Follow the steps to manually configure the SiWx917 SoC with Latest Ozone Debugger.

Steps to Configure the SiWx917 SoC on the JLink-RTT Logging and Ozone Debugger

1. Update the JlinkDevices.xml and ELF files found in the Matter Artifacts page.

   • Download the JLinkDevices.xml file and copy it in your Ozone installation path shown in this JLinkDevices folder. If there is no JLinkDevices Folder, create a JLinkDevices folder and copy the JlinkDevices.xml file.

   • In the JLinkDevices folder, create a Devices folder and then create a sub-folder named SiliconLabs.

   • Download the ELF file (Flash driver) and copy it in the created SiliconLabs folder.

2. Launch Ozone. The SiWx917 Dual Flash SoC device should be visible in the Device field’s selection list.

   

3. In the New Project Wizard:

   • Click the three dots (...) on the Device tab and select the Manufacturer as Silicon Labs.

   • Select the Device as Si917DualFlash.

   • Click OK.
