nrf528520 BLE DFU OTA Issue

Question

nrf52820 custom board nRF5_SDK_17.1.0_ddde560 s112_nrf52_7.2.0_softdevice secure_bootloader_ble_s112_pca10100e I tried to incorporate ble dfu to my application but the bootloader never finds the application, neither when hex files (of app + softdevice + bootloader + settings) are programmed via nrf programmer or hex files ( softdevice + bootloader + settings) are programmed via nrf connect programmer and app is loaded via the nrf connect cell phone app. All i see is the DFUTarg being advertised and I have also confirmed it with RTT output. I have attached the 4 relevant files here. here is the command I used to generate settings: nrfutil settings generate --family NRF52QFAB --application lazyiot_axis_nrf52820.hex --application-version 1 --bootloader-version 2 --bl-settings-version 2 settings.hex and here is the screen shot of all the files loaded in nrf programmer: Please provide guidance. This is the blocking issue before we start production. /* Linker script to configure memory regions. */ SEARCH_DIR(.)
