It was a POC on Yocto Zeus BSP and has no plan on kirkstone BSP.
But you can try to copy the “meta-robot-platform” folder from Zeus BSP and modify “imx/meta-robot/conf/distro/layer.conf” for LAYERSERIES_COMPAT_imx-robot with kirkstone support.
I’ve resolved the issue on my own.
I successfully built an image where ROS2 operates and set up the cross-compilation environment.
I’m closing this topic. No reply necessary.
