Hi Hieu,

Thanks for confirming. I did see the warning but assumed the sample would still build but just not be useful for running.

Hi corytodd-a,

The https://github.com/nrfconnect/sdk-nrf/tree/main/samples/bootloader sample contains the source code for the Nordic Secure Immutable Bootloader (NSIB). It should be included as a child image in a multi-image build, rather than being built stand-alone. While it is technically possible to build the NSIB by itself and merge it into other application images, this process is not supported.

Please refer to our guide here as a starting point: Bootloaders and DFU.
