If so, the first thing that comes to mind is that you may have a newer revision of the nRF52840 on the dongle. Can you check the chip markings on both boards and let me know if that is the case? If so, it could be that you are using a too old version of nrfjprog that does not know about the new revision, which can be fixed by updating to the latest version of the <a href="https://www.nordicsemi.com/Products/Development-tools/nrf-command-line-tools/download">nRF Command Line Tools</a>.</p><div style="clear:both;"></div>
