https://devzone.nordicsemi.com/f/nordic-q-a/59314/i-can-t-connect-pca10040-to-pcI&#39;m using PCA10040 to test nRF52832. But I can&#39;t see J-link device after connecting USB. I installed J-link(segger), nRFgo studio, nrf command. But I can&#39;t see my PCA10040 board. I can see J-link device if I connect J-link equipment as below.en-USTelligent Community 13Sun, 22 Mar 2020 23:21:38 GMThttps://devzone.nordicsemi.com/thread/241013?ContentTypeID=1Sun, 22 Mar 2020 23:21:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c0be5aad-d202-4157-9ab7-bf0b68584390Roger01<p>Oh!

I see from your 2nd screenshot that the debugger SN is not even showing up so I&#39;m wondering if the Jlink is getting power. Have you tried with different USB cables?</p><div style="clear:both;"></div>
