&lt;p&gt;It looks strange that you get this. Please take a look at the how it&amp;#39;s set in the &lt;a href="https://github.com/nrfconnect/sdk-mcuboot/blob/main/boot/zephyr/boards/thingy91_nrf52840.conf#L10"&gt;Kconfig file for&amp;nbsp;&lt;/a&gt;&lt;span&gt;&lt;span dir="ltr"&gt;&lt;a href="https://github.com/nrfconnect/sdk-mcuboot/blob/main/boot/zephyr/boards/thingy91_nrf52840.conf#L10"&gt;thingy9160_nrf524840 board&lt;/a&gt;. Maybe this helps?&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;span dir="ltr"&gt;-Priyanka&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: What is the minimum required MCUboot partition size ?</title><link>https://devzone.nordicsemi.com/thread/435665?ContentTypeID=1</link><pubDate>Tue, 11 Jul 2023 09:41:23 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:195bc129-4c09-41a8-9d64-0445ac5df4e3</guid><dc:creator>zaman_turja_solshare</dc:creator><description>&lt;p&gt;hi,&lt;/p&gt;
&lt;p&gt;im working in ncs environment with visual code studio, in the prj.conf-&lt;/p&gt;
&lt;div&gt;&lt;span&gt;&lt;span&gt;CONFIG_PM_PARTITION_SIZE_MCUBOOT this config is not found, it says &amp;quot;unknown symbol&lt;/span&gt;&lt;/span&gt;
&lt;div&gt;
&lt;div&gt;&lt;span&gt;CONFIG_PM_PARTITION_SIZE_MCUBOOT&lt;/span&gt;&amp;quot;&lt;br /&gt;&lt;br /&gt;any idea ?&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: What is the minimum required MCUboot partition size ?</title><link>https://devzone.nordicsemi.com/thread/432951?ContentTypeID=1</link><pubDate>Mon, 26 Jun 2023 11:58:47 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:09341f57-5022-4917-8e8e-8728a0798341</guid><dc:creator>Priyanka</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;Maybe this could help:&amp;nbsp;&lt;a href="https://github.com/nrfconnect/sdk-mcuboot/blob/main/boot/zephyr/prj_minimal.conf"&gt;https://github.com/nrfconnect/sdk-mcuboot/blob/main/boot/zephyr/prj_minimal.conf&lt;/a&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Also, the size of MCUBoot depends on how many for the MCUBoot features you have enabled. The MCUBoot partition size can be configured using&amp;nbsp;&lt;span&gt;&lt;span dir="ltr"&gt;&lt;a title="https://github.com/nrfconnect/sdk-nrf/blob/e83eaec6bf26e2ee1234608b9b5791b6ce56b623/modules/mcuboot/boot/zephyr/kconfig#l21c8-l21c33" href="https://github.com/nrfconnect/sdk-nrf/blob/e83eaec6bf26e2ee1234608b9b5791b6ce56b623/modules/mcuboot/boot/zephyr/Kconfig#L21C8-L21C33" rel="noopener noreferrer" target="_blank"&gt;CONFIG_PM_PARTITION_SIZE_MCUBOOT&lt;/a&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;There is this sample where it shows how they have decreased the MCUBoot memory footprint:&amp;nbsp;&lt;a href="https://github.com/nrfconnect/sdk-nrf/blob/e83eaec6bf26e2ee1234608b9b5791b6ce56b623/applications/machine_learning/configuration/nrf5340dk_nrf5340_cpuapp/child_image/mcuboot/prj.conf#L42-L52"&gt;https://github.com/nrfconnect/sdk-nrf/blob/e83eaec6bf26e2ee1234608b9b5791b6ce56b623/applications/machine_learning/configuration/nrf5340dk_nrf5340_cpuapp/child_image/mcuboot/prj.conf#L42-L52&lt;/a&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Please take a look at&lt;a href="https://devzone.nordicsemi.com/f/nordic-q-a/85319/how-to-resize-mcuboot-partition-in-zephyr#:~:text=The%20size%20of%20MCUBoot%20partition%20is%2048KB%20by%20default."&gt; this ticket&lt;/a&gt; too.&lt;/p&gt;
