Can done with a&nbsp;<em>module</em>. That code can be triggered using&nbsp;<code>CONFIG_MCUBOOT_ACTION_HOOKS </code>calling&nbsp;<code>mcuboot_status_change(mcuboot_status_type_t status) </code>function that your module will need to implement<code>.</code></p> <p>No idea if the default flash layout leaves enough room for this modification in the mcuboot partition.</p><div style="clear:both;"></div>
