The problem is just what they error message is trying to say.
There's no declared machine compatibility between that board
and the linux-yocto-rt recipe.
You could create a bbappend that contained both a BSP
definition and that sets the compatibility. But I can't
say if it would, or wouldn't have runtime issues.
i.e. you need to append beaglbone-yocto to the COMPATIBLE_MACHINE
variable.
You also need a BSP definition for the -rt kernel, but at
a glance, it looks like there's already one in the kernel-cache,
so you should get a valid configuration.
