&lt;p&gt;PDK (Preview Development Kit) is not supported with NCSv3.0.2.&amp;nbsp;&lt;a href="https://docs.nordicsemi.com/bundle/ncs-3.0.2/page/nrf/app_dev/device_guides/nrf54l/index.html"&gt;Developing with nRF54L Series&lt;/a&gt;&amp;nbsp;lists the DK versions supported.&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1754672367993v1.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;I recommend purchasing a Development Kit that is supported by the later versions of NCS.&lt;/p&gt;
&lt;p&gt;Since you have the PDK you could try the supported NCS version listed.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
