How do I write with MCUboot &amp; DFU &amp; application?

Are you doing DFU over USB or BLE? If so, how have you done this? Like the serial recovery described for the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/nrf_desktop/README.html#configuring-serial-recovery-dfu">nRF Desktop</a>? If so, or with other NCS approaches we support, mcumgr is the tool to use to perform DFU from a PC.</p><div style="clear:both;"></div>
