E.g. if you add CONFIG_BOOTLOADER_MCUBOOT=y to the prj.conf of your sample, this project will be used.</p> <p>You don&#39;t need to build it separately by the way, it will get built automatically when&nbsp;setting&nbsp;<span>CONFIG_BOOTLOADER_MCUBOOT=y as explained above. The MCUboot and application hex files will get merged into &lt;application&gt;build/zephyr/merged.hex.</span></p> <p><span>Best regards,</span></p> <p><span>Simon</span></p><div style="clear:both;"></div>
