Disable SEGGER J-Link OB Debuggerhttps://devzone.nordicsemi.com/f/nordic-q-a/41638/disable-segger-j-link-ob-debuggerHi Is there a way to disable the on-board SEGGER J-Link ? ( jumpers ? ) The reason is that in our design we will use an external J-Link ( no space for OB ) , so we want to make sure we can connect to external J-Link ?

Yes, you can toggle the SW 6 or unplug the USB cable to J2 to disconnect the interface MCU for the nRF52840 DK.&nbsp;</p> <p>Documentation:<a href="https://www.nordicsemi.com/DocLib/Content/User_Guides/nrf52840_dk/latest/UG/nrf52840_DK/operating_modes">Doclib</a></p><div style="clear:both;"></div>RE: Disable SEGGER J-Link OB Debuggerhttps://devzone.nordicsemi.com/thread/162039?ContentTypeID=1Mon, 17 Dec 2018 10:46:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c8c08c41-2c12-4306-a124-db89c31b33abran<p>Can I set &quot;sw6&quot; on DK to &quot;nRF Only&#39; ? and then connect wires to SWD gpio ?&nbsp;</p><div style="clear:both;"></div>RE: Disable SEGGER J-Link OB Debuggerhttps://devzone.nordicsemi.com/thread/162038?ContentTypeID=1Mon, 17 Dec 2018 10:44:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:908e9b6f-c1c2-4ff0-8abe-8605702d5863ran<p>nRF52840 DK</p><div style="clear:both;"></div>RE: Disable SEGGER J-Link OB Debuggerhttps://devzone.nordicsemi.com/thread/162031?ContentTypeID=1Mon, 17 Dec 2018 10:08:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:30f4a56a-93a2-4684-8978-9d820d7d10faJared<p>Hi,</p> <p>The solder bridge on the nRF52 DK can be cut to disable the power for the interface MCU.
