The port connection appears to be working properly in Device Manager, so the connector for the PPK seems to be functioning correctly. Therefore, I suspect that the issue is related to the internal firmware.<img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1754447206756v1.png" alt=" " /></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/544615?ContentTypeID=1Tue, 05 Aug 2025 12:07:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:204a7e15-1abc-4437-bed9-6cb1b747b7eeKenneth<p>Hello,</p> <ul> <li>Do any apps open? or do all fail to open?</li> <li>Can you say a few more words on how does it fail?</li> </ul> <p>Kenneth</p><div style="clear:both;"></div>
