It will look like this: Inside the application folder you will have one folder called child_image. Inside the child_image folder, create a file name called mcuboot.conf. There you can add this config&nbsp;<span>CONFIG_ENABLE_DC_DC=n. Try this and let me know if it works.</span></p> <p><span>Thnaks.</span></p> <p><span>BR<br />Kazi</span></p> <p><span></span></p><div style="clear:both;"></div>
