Hi Hung,

Sorry for the late reply, currently blocked on this as I am waiting for support on a related ticket so haven't got to test this yet

Hi Ronan,

Have you done any application update via FOTA ? If you haven't please have a look at this example: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf9160/http_update/application_update/README.html

I assume what you want to achieve is to do MCUBoot update itself. If it's the case I would suggest to have a look at this similar case: https://devzone.nordicsemi.com/f/nordic-q-a/86385/secure-bootloader-chain-two-stage-upgradable-bootloader-mcuboot

In the case I pointed to an example that one of my coworkers has made an example on how to do it with SMP server. The next step is to combine the http update example so that it would do MCUBoot update instead of application update.
