https://devzone.nordicsemi.com/f/nordic-q-a/124430/nrf52840-dk-not-getting-detected-by-pcI had used nRF52840 DK sometime ago and successfully tested it with different codes. But now when I connect the kit to the PC, it is not getting detected by the same PC that I used last time. I am running Windows 11 and I have installed J-Link SEGGERen-USTelligent Community 13Tue, 23 Sep 2025 06:01:01 GMThttps://devzone.nordicsemi.com/thread/549486?ContentTypeID=1Tue, 23 Sep 2025 06:01:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d4d3da83-e737-462a-ba42-2be913bb9c13shaunakvyas1<p><span>Hi Asbj&oslash;rn</span></p> <p><span>I had by mistake kept the VEXT switch ON. That was causing this issue. After putting it OFF, I am now able to access and program the board.</span></p> <p><span></span></p> <p><span>I kindly request you to close this ticket.</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/549190?ContentTypeID=1Thu, 18 Sep 2025 13:33:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1672a902-9e28-4cd3-b138-7e1bec002fc0Asbj&#248;rn<div>Hello Shaunak,</div> <div></div> <div>Q1: There&#39;s a green LED that should lit up, LED5, when you connect the USB cable. Does this light up?</div> <div>Q2: Which USB port are connecting the cable to? J2 or J3?</div> <div>Q3: SW10 right next to the power switch, is it set to OFF as well?</div> <div></div> <div>The fact that it doesn&#39;t show up at all makes me think that there a switch somewhere set in wrong position. <a href="https://docs-be.nordicsemi.com/bundle/ug_nrf52840_dk/page/UG/dk/images/nRF52840/pca10056_v1_0_0_top_nfc.png?_LANG=enus">https://docs-be.nordicsemi.com/bundle/ug_nrf52840_dk/page/UG/dk/images/nRF52840/pca10056_v1_0_0_top_nfc.png?_LANG=enus</a></div> <div></div> <div></div> <div>Best regards</div> <div>Asbjørn</div><div style="clear:both;"></div>
