 I want to disable firmware signed key validation from mcuboot, when it validates a new image available through DFU. 
 Kindly suggest how to disable key validation from mcuboot..? Thanks,

&lt;p&gt;I need to do this as my application has a module which downloads firmware image &amp;amp; validates it by verifying the encryption &amp;amp; key.&lt;br /&gt;&lt;br /&gt;Hence I do not want the same validation to happen again when mcuboot tries to swap new image with old image.&lt;br /&gt;&lt;br /&gt;Thanks,&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Suppress/disable private key validation in mcuboot</title><link>https://devzone.nordicsemi.com/thread/360891?ContentTypeID=1</link><pubDate>Wed, 30 Mar 2022 17:55:24 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:a6a2db22-14c3-49f5-a0eb-3ca6455de1f7</guid><dc:creator>Edvin</dc:creator><description>&lt;p&gt;Why do you need to disable it?&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I guess you can use the config&amp;nbsp;&lt;/p&gt;
&lt;pre&gt;CONFIG_BOOT_SIGNATURE_TYPE_NONE&lt;/pre&gt;
&lt;p&gt;When you set this to &amp;quot;y&amp;quot;, it will not verify the cryptographic signature of the image at boot or prior to upgrade.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
&lt;p&gt;Edvin&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
