Yes. First thing to find out is what you need in terms of real-time : *) A vanilla Linux kernel with preemption enabled and proper process priorities ; *) A Linux kernel patched with PREEMPT_RT *) The more radical approach provided by Xenomai All three are possible with Buildroot, it's rather what kind of real-time guarantees and latencies you need and how much effort you're ready to spend on achieving those guarantees.
