I'm attempting to migration from using MCUBOOT as a child image to sysbuild using SDK 2.8.0.
Everything boots fine when building using a child image, but when switching to sysbuild I initially get a warning that BOOT_MAX_IMG_SECTORS is too small, followed by an error from MUCBOOT that the image is invalid.
If I increase BOOT_MAX_IMG_SECTORS to 512, the bootloader appears to not even start. I never get as far as seeing the message "Starting bootloader".
As far as I can tell, the configurations are virtually identical, I've just moved the configurations into the 'sysbuild' folder.
Here is a copy of build_sysbuild/zephyr/.config
