GPIO NRF54L15 not wokinghttps://devzone.nordicsemi.com/f/nordic-q-a/127344/gpio-nrf54l15-not-wokingI designed a circuit using the NRF54 to connect via Bluetooth and control several peripherals. I program the chip using the Debug Out of the NRF54L15 DK . The code can be flashed successfully, but the GPIO is not working . What could be the reason? en-USTelligent Community 13Wed, 11 Mar 2026 13:07:17 GMTRE: GPIO NRF54L15 not wokinghttps://devzone.nordicsemi.com/thread/563027?ContentTypeID=1Wed, 11 Mar 2026 13:07:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:577fdaad-0e43-4723-8f9b-6f1146aea491Kenneth<p>Taking a step back, is controlling this specific pin the only thing not working, or doesn&#39;t anything work (neither using other pins or other basic examples you can find in the nRF Connect SDK)?</p> <p>Maybe share the zephyr.dts and .config file(s) you can find under your build folder.</p> <p>Kenneth</p><div style="clear:both;"></div>RE: GPIO NRF54L15 not wokinghttps://devzone.nordicsemi.com/thread/562981?ContentTypeID=1Wed, 11 Mar 2026 01:55:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:07ab1aea-cd22-4cf7-945e-fab33555a72cNam<ul> <li data-section-id="1aexjom" data-start="175" data-end="242"> <p data-start="177" data-end="242"><strong data-start="177" data-end="240">I followed your instructions, but it&rsquo;s still not working.&nbsp;&nbsp;<br /><br /><span>CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n</span><br /><span>CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y</span></strong></p> <strong data-start="177" data-end="240"><span></span></strong></li> </ul><div style="clear:both;"></div>RE: GPIO NRF54L15 not wokinghttps://devzone.nordicsemi.com/thread/562980?ContentTypeID=1Wed, 11 Mar 2026 01:45:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:75d59e50-3470-4839-9834-fd0bd52e3994Nam<p><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1773193342124v1.png" alt=" " />&nbsp; I<span>&nbsp;have an external 32MH.
