Is there a problem with the nrf52840 schematic?https://devzone.nordicsemi.com/f/nordic-q-a/116670/is-there-a-problem-with-the-nrf52840-schematicNRF_CLOCK-&gt;TASKS_HFCLKSTART = 1; while (NRF_CLOCK-&gt;EVENTS_HFCLKSTARTED == 0); NRF_CLOCK-&gt;EVENTS_HFCLKSTARTED = 0; I finally figured out the problem with my custom board I think it&#39;s a HFXO clock problem. It doesn&#39;t go any further with the above codeen-USTelligent Community 13Mon, 25 Nov 2024 09:58:05 GMTRE: Is there a problem with the nrf52840 schematic?https://devzone.nordicsemi.com/thread/511853?ContentTypeID=1Mon, 25 Nov 2024 09:58:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9a9826c4-4254-464c-b96a-fb4c5888ed8aPriyanka<p>Hi Kim,</p> <p>We usually recommend using the values and components in the reference schematic exactly in your design. The component values seem a bit different from the values that are mentioned in the reference.</p> <p>You also seem to be missing a 15uH series inductor at the DCC pin.&nbsp;</p> <p>There are also places where the 4.7uF cap seems to be missing or replaced with other values.</p> <p>Regards,</p> <p>Priyanka</p><div style="clear:both;"></div>
