You need&nbsp;<span>--sd-req 0x0100, 0x00CA&nbsp;(new SD and SD now running), and --sd-id 0x0100 for the new SD. If you have any issues regarding this update, please provide the commands used to generate the package and your update flow.&nbsp;</span></p> <p><span>-Amanda H.</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/277457?ContentTypeID=1Wed, 28 Oct 2020 16:05:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:45ccf83d-ba73-445d-97c2-38b1fac15fc8Ivan Herrera<p>1. 0x0100</p> <p>2.
