I am currently migrating from ncs 2.5.0 to 2.7.0 and am trying to move to using sysbuild instead of child / parent image. I have an out of tree flash driver that currently gets built and configured as part of the mcuboot child image build.
So far, organising the configs and overlays for mcuboot and my app is pretty straightforward (they are organized under sysbuild/), but when I try to enable my out of tree flash driver in sysbuild/mcuboot/boards/[board].conf it says my config symbols are undefined.
In the child / parent image set up we simple did something like this in app/CMakeLists.txt
list(append zephyr_extra_modules ${cmake_current_list_dir}/../drivers/flash/my_out_of_tree_driver/)
this doesn't seem to work. neither does adding another CMakeLists.txt file in the sysbuild/mcuboot directory. What's the best way to let the mcuboot sysbuild know about the location of my driver?
