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.

Best regards,

Thomas
