The file should be called either app_update. bin or update.bin.&nbsp;</p> <p>However, you need to enable the&nbsp;<span>BOOTLOADER_MCUBOOT configuration before building to generate the file, which is probably why you can&#39;t find it. </span></p> <p><span>Add the following line to the prj.conf file of the example you want to build:</span></p> <p><span><pre class="ui-code" data-mode="text">CONFIG_BOOTLOADER_MCUBOOT=y</pre></span></p> <p><span>Best regards,</span></p> <p><span>Heidi</span></p><div style="clear:both;"></div>
