The process of swapping is done by doing a confirm command (usually with OTA it &#39;s done automatically)</p> <p>If you want to know the location on your device, you can look at the partition.yml file inside build folder.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/358599?ContentTypeID=1Thu, 17 Mar 2022 10:29:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:df39506b-0241-4138-ba2e-d468e8a0c867qwertynoon<p>Hi.
