Hey Mike,
I just found this old thread and wondered if you could share the work
you've done so far.
I'm interested in using ROS2 in an embedded system with buildroot and
cross-compilation to aarch64. I don't need a full ros distribution,
just enable some basic C/C++ programs on the target to talk with other
ros nodes on the network via topics, services and actions.
Maybe having just a very stripped-down version of ROS2 in buildroot
would be useful for others as well.

Thanks,
Stefan
