For a novice to NXP Freescale builds, what setup would you recommend as 
a basic test Yocto build for a Wandboard IMX6 dual lite system in order 
to test the performance of the hardware video processing system using 
gstreamer*imx (VPU etc) ?

Would fslc-x11 or fslc-xwayland distro with the linux-fslc-imx kernel be 
the best approach or would some fsl-* distro with the linux-imx kernel 
be the best approach ?

The standard Wandboard build uses linux-fslc which does not seem to 
support the imx hardware features and so I am trying to build a suitable 
test platform but having no luck trying various build combinations that 
either wont build or wont run properly in various ways, so any pointers 
would be gratefully received !
