When I did NXP released builds I would use fsl-wayland distro but if memory serves me right a core-image-minimal would not boot. Only core-image-base images did and they were quite large.
I do need to create my own distro but kind of would like to start from core-image-minimal and build up rather than take something like fsl-wayland and try to figure out what I don't need. Being new to NXP family this approach "feels" more logical.

I'll look. Thanks
