Hi Sravan,

These are the samples that you can refer:

SMP Server: https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/samples/subsys/mgmt/mcumgr/smp_svr/README.html#smp-svr
MCUboot minimal configuration: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/zephyr/smp_svr_mini_boot/README.html#mcuboot-minimal-configuration

A few helpful links that you can go through:

Bootloaders and DFU overview (MCUboot + NSIB): https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/bootloaders_dfu/mcuboot_nsib/bootloader_mcuboot_nsib.html
nRF54L device DFU/secure boot specifics (keys, signatures, encryption, KMU, etc.): https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/device_guides/nrf54l/dfu_config.html , https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/device_guides/nrf54l/index.html

We also have a DevAcademy course that explains DFU here: https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-9-bootloaders-and-dfu-fota/
