https://devzone.nordicsemi.com/f/nordic-q-a/118251/when-porting-to-v2-9-0-the-mcu-does-not-functionI attempted to flash the Matter lock example to my custom board, but the MCU shows no activity. Back in v2.6.1, I used the following configuration, which worked. How should I implement this in version 2.9.0?

Unfortunately this is poorly documented as of now, but you can see it here:&nbsp;<a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/releases/migration-guide-4.0.html#regulator">https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/releases/migration-guide-4.0.html#regulator</a>&nbsp;</p> <p>Let me know if this resolves the implementation</p> <p>Kind regards,<br />Andreas</p><div style="clear:both;"></div>
