 In my custom hardware with nrf5340 I am not using LFXO, so in proj.conf I am doing as below 
 
 # clock 
 CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC =y 
 CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL =n 
 CONFIG_CLOCK_CONTROL_NRF_K32SRC_500PPM =y 
 CONFIG_SOC_ENABLE_LFXO</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 07 Aug 2023 10:48:24 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/102585/does-mcuboot-ble-dfu-require-lfxo-nrf5340-not-working-without-lfxo-if-dfu-is-enabled" /><item><title>RE: Does MCUBOOT BLE DFU require LFXO ? nrf5340 not working without LFXO if DFU is enabled</title><link>https://devzone.nordicsemi.com/thread/440082?ContentTypeID=1</link><pubDate>Mon, 07 Aug 2023 10:48:24 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:a23f7213-d084-45db-92fa-942b0133fc8f</guid><dc:creator>Edvin</dc:creator><description>&lt;p&gt;Similarly to how you do it to the hci_rpmsg child image.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Create a folder in you application folder called child_image. Inside there, there you can add two files:&lt;/p&gt;
&lt;p&gt;mcuboot.conf&lt;/p&gt;
&lt;p&gt;hci_rpmsg.conf&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Inside these files you can append configurations to your child images, which will be added to the default child images&amp;#39; configurations.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;

&lt;p&gt;What child image did you add these configs to?&lt;/p&gt;
[quote user=""]in both app and child_image conf.[/quote]
&lt;p&gt;Did you put it in both the hci_rpmsg and the mcuboot child images?&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
