First, a little rant... :)

It's unfortunate, but this still causes lots of confusion. Some purists among 
us will say that is not Yocto, but Poky. Case in point - which "yocto" git 
repository you cloned from http://git.yoctoproject.org/ ?

Same applies to a 'vanilla' yocto image, which does not exist. It would rather 
be useful to specify which exact image for which MACHINE you are trying to 
build. A little bit more detail is always helpful...


And now to the resolution part. I see you already used BBMASK as prescribed in 
the README, since you get past the unset LICENSE error... The below error 
happens when you build for a MACHINE that is overshadowed by another BSP 
layer that does not define MACHINE_KERNEL_PR. This MACHINE_KERNEL_PR variable 
is set in MACHINE definitions of meta-ti BSP layer and then used in other 
recipes within meta-ti and different layers.

In other words, you are trying to build for "beagleboard" machine, which gets 
also defined by meta-yocto-bsp layer, besides meta-ti. The solution is simple -
you need to move meta-ti above meta-yocto-bsp in your bblayers.conf or just 
remove meta-yocto-bsp from the list, if you are not planning on building any 
of the reference platforms. That way you'll get the machine definition from 
meta-ti layer and not from meta-yocto-bsp.

After that, core-image-minimal and some other images should build fine. Good 
luck!
