&lt;p&gt;The error message (-19, &amp;quot;No such device&amp;quot;) and the log referencing JEDEC ID 0, which suggests that the QSPI device may not be connected or powered correctly. Could you please provide details on how the device is powered and specify the exact pins being used for QSPI? Although the overlay references default and qspi_sleep, it would be helpful to confirm the exact pins in use. Additionally, if you have access to a logic analyzer, probing the SPI pins might offer further insights into the issue.&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I have checked the physical connections with the help of logic analyzer they are correct as per my understanding. And now I have also verified the sfdp-bfp values. But now before the boot when the kernel does the entry level device initialization it is getting failed for this serial flash.&lt;/p&gt;
&lt;p&gt;I am getting an error&amp;nbsp;[00:00:00.253,173] &amp;lt;err&amp;gt; qspi_nor: JEDEC id [00 00 00] expect [c2 20 1b]&lt;/p&gt;

&lt;p&gt;Double-check the physical connections to ensure the QSPI lines (CLK, CS, DQ0, DQ1, DQ2, DQ3) are correctly connected between the nRF5340 and the MX66L1G.&amp;nbsp;The JEDEC ID in the overlay file should match the actual JEDEC ID of the MX66L1G flash chip. The JEDEC ID provided is&amp;nbsp;&lt;code&gt;[c2 20 1b]&lt;/code&gt;. Ensure that this is correct. You might need to refer to the MX66L1G datasheet to verify the JEDEC ID.&lt;/p&gt;
&lt;p&gt;I am not sure, but have you cross-checked the sfdp-bfp values inside the overlay with the data sheet of MX66L1G?&lt;/p&gt;
&lt;p&gt;Kind Regards,&lt;/p&gt;

&lt;p&gt;Sorry for the late response. It&amp;#39;s the summer vacation period here in Norway, and the increased workload has caused the delay&lt;/p&gt;
&lt;p&gt;&lt;span style="font-family:inherit;"&gt;While reviewing the &lt;/span&gt;&lt;code&gt;prj.config&lt;/code&gt;&lt;span style="font-family:inherit;"&gt;, I noticed that you have enabled serial recovery in the MCUboot configuration. However, from your thread, it seems you are only looking for serial DFU, correct? Please confirm this. The guide I pointed you to works with the newer version of the nRF Connect SDK, but your version is a bit older, which might cause some configuration differences. If possible, I recommend updating your application to the latest version.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;The &amp;quot;bootable status false&amp;quot; message indicates that the device will not boot from this image, and &amp;quot;unavailable hash&amp;quot; suggests that the hash of the image in slot 0 is not available. This could be due to an issue with how the image was created, signed, or uploaded. I suspect this issue might be due to improper signing of the image. Are you properly using the &lt;a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/mcuboot/imgtool.html"&gt;image signing with Imgtool&lt;/a&gt;? Please refer to the section on &lt;a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/config_and_build/bootloaders/bootloader_signature_keys.html"&gt;Image Signing&lt;/a&gt; for guidance.&lt;/p&gt;
&lt;p&gt;Also, check the &lt;code&gt;mcumgr&lt;/code&gt; configurations you have enabled in the &lt;code&gt;prj.config&lt;/code&gt;. I recommend comparing your application with &lt;a href="https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/smp/mcuboot_smp_uart"&gt;this sample&lt;/a&gt;, as it is more relatable to your SDK version. Additionally, check the repository for some &lt;a href="https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples"&gt;bootloader samples&lt;/a&gt; with external flash.&lt;/p&gt;

&lt;p&gt;I am configuring the image version with a config in the prj.conf&lt;/p&gt;

&lt;/div&gt;
&lt;p&gt;It seems like there is an issue with the mcumgr commands compatibility with ncs 2.3.0, because now if I am trying to upload the secondary image in the external flash, image upload is not taking place.&lt;/p&gt;

&lt;p&gt;Have you set the external flash in both `app.overlay` and `mcuboot.overlay` as&lt;a href="https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-8-bootloaders-and-dfu-fota/topic/exercise-2-dfu-over-usb-adding-external-flash/#:~:text=We%20can%20tell,child_image/mcuboot.overlay"&gt; mentioned here&lt;/a&gt;? &lt;a href="https://github.com/NordicDeveloperAcademy/ncs-inter/blob/main/lesson8/inter_less8_exer2_solution/child_image/mcuboot.overlay#L13"&gt;See this sample&lt;/a&gt; for reference. Could you share the entire log and overlay files? Please use the insert tab to share the log and files, as it is a bit hard to go through the screenshots.&lt;/p&gt;
&lt;p&gt;Kind regards,&lt;/p&gt;
