Hello,

Could you please let me know which Nordic chip you're working with? Also, is this a custom board or a development kit?

I assume you're using nRF Connect SDK version v2.9.1, please correct me if that’s not the case.

I’m not quite sure what you mean by prj_fota.config based on the Light Switch sample. Additionally, I don't see any configuration on your end that enables MCUboot. You likely need to include CONFIG_BOOTLOADER_MCUBOOT to enable the bootloader.

I’d also appreciate it if you could share the complete build log.

Kind regards,
Abhijith

Thank you,

The issue is resolved. The CONFIG_BOOTLOADER_MCUBOOT was not being defined globally. So added the command to enable it globally from CMakeLists.txt
