nRF COMP driver prevents Zephyr from booting on nRF54L15https://devzone.nordicsemi.com/f/nordic-q-a/125801/nrf-comp-driver-prevents-zephyr-from-booting-on-nrf54l15Hi, I&#39;m trying to use the nRF COMP peripheral in Zephyr. My application boots and runs normally until I enable the DeviceTree overlay for the COMP. As soon as the overlay is added, the device stops booting (no logs appear). If I remove the overlay entirelyen-USTelligent Community 13Wed, 26 Nov 2025 08:24:03 GMTRE: nRF COMP driver prevents Zephyr from booting on nRF54L15https://devzone.nordicsemi.com/thread/555455?ContentTypeID=1Wed, 26 Nov 2025 08:24:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a1e82e94-cc31-467d-b884-8aaf75ad4642Benjamin<p>Hi,<br />I reproduced your issue. You are setting the comparator input&nbsp;to AIN0 which on the nRF54L15 is P1.04. See&nbsp;<a href="https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/chapters/pin.html#ariaid-title7">pin assignments</a>. This is the same pin that is used for UART and causes a conflict here. You will have to change the analog input pin or the UART pin arrangement. I changed the input to&nbsp;AIN5 and then your code worked fine.<br /><br />Best regards,<br />Benjamin</p><div style="clear:both;"></div>
