PPK faulty readinghttps://devzone.nordicsemi.com/f/nordic-q-a/47924/ppk-faulty-readingHi all, we has experienced two PPK boards start to give faulty reading after several uses. I attached two screenshots about current reading with same setting on the DEV board and also the target DUT board. It appears to be hardware failure on the PPKen-USTelligent Community 13Fri, 07 Jun 2019 12:54:20 GMTRE: PPK faulty readinghttps://devzone.nordicsemi.com/thread/191665?ContentTypeID=1Fri, 07 Jun 2019 12:54:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:83d0421a-c318-4d76-8391-02d342739dd9Jared<p>Hi,</p> <div><span>Could you try powering the DK and the DUT via an <a href="https://infocenter.nordicsemi.com/topic/ug_ppk/UG/ppk/PPK_user_guide_PPK_on_customHW_with_nRF5xDK.html?cp=6_6_5_4">external power source </a>and see if the issue persists.</span></div> <div></div> <p>Regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>RE: PPK faulty readinghttps://devzone.nordicsemi.com/thread/190904?ContentTypeID=1Tue, 04 Jun 2019 18:58:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6f3b07b1-df63-4395-8f87-73866ab221adHacking365<p>My set up is PPK plug into DK(with jumper cut), power and debug through DK via micro USB cable.PPK DUT switch is External, PPK power select is on Reg.
