In that case you might need external flash to store the image if&nbsp;there is no space in the internal flash.</p> <p>If you are using USB to do update, then you can use serial recovery to do the update using USB:<br /><a href="https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/serial_recovery">https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/serial_recovery</a>&nbsp;</p> <p>Kenneth</p><div style="clear:both;"></div>
