https://devzone.nordicsemi.com/f/nordic-q-a/77178/updating-mcuboot-otaI have found that you cannot update MCUBoot unless you also have the NRF Immutable Secure Bootloader, If i have this then i cannot update the Immutable bootloader. Is there a way so that i can basically update every component on the Chip.
