Can you try adding &#39;<span>DIAGNOSTIC=1&#39;, as described in&nbsp;<a title="Building the latest OpenThread libraries" href="https://infocenter.nordicsemi.com/topic/sdk_tz_v4.1.0/thread_ot_libraries_building.html#thread_ot_libraries_building_1">Building the latest OpenThread libraries</a>?</span></p> <p><span>Also, which OpenThread commit are you building from?</span></p> <p><span>Best regards,<br />Jørgen</span></p><div style="clear:both;"></div>
