Thanks Paul, more and more I regret my early decision to start out with TI's released 7.0 SDK using Arago which is on Dylan. 
It's taken them forever to create another release. 
At the time I was new to the Sitara processor, OE and Bitbake and figured I should stay with released code, now I see them error of my ways. 

Thanks again,
Matt S.
