 We&amp;#39;re using the out-of-the-box NCS 1.6.1 SDK / Zephyr / MCU boot process for our application. After upgrading the firmware, either via a dfu-utils flash to slot 1, or performing a DFU OTA (via the default MCU manager&amp;#39;s SMP implementation -- CONFIG_MCUMGR_SMP_BT</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 14 Mar 2022 10:12:59 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/85742/nrf-connect-sdk-1-6-1-automatically-confirming-of-firmware" /><item><title>RE: nRF Connect SDK 1.6.1 : Automatically confirming of firmware</title><link>https://devzone.nordicsemi.com/thread/357896?ContentTypeID=1</link><pubDate>Mon, 14 Mar 2022 10:12:59 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:3dce55e8-0d76-41d7-8cd3-daa8db938f57</guid><dc:creator>H&amp;#229;kon Alseth</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
[quote user=""]&lt;p&gt;the device successfully boots into the new version of the firmware. But despite us invoking:&amp;nbsp;&lt;/p&gt;
&lt;p&gt;boot_write_img_confirmed();&lt;/p&gt;
&lt;p&gt;during the new firmware&amp;#39;s execution with a return code of zero, after a power-cycle, MCU is rolling back to the previous version.&lt;/p&gt;[/quote]
&lt;p&gt;Do you have the secondary slot&amp;nbsp;located in external memory, or internal flash?&lt;/p&gt;
&lt;p&gt;Could you share the log output of the process?&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Kind regards,&lt;/p&gt;
