Issues encountered when bringing up Beagle Board

Hi People whom want to know,
I’m a newbie of Beagle. Presently, I have a kernel image on hand, but it does not support Neon and /dev/videoX(1,2). They’re necessary for me to utilize the advantage of Resizing & Scaling of Beagle. Could you please help about these two issues? Many thanks in advance.

Best Regards,
David Wan
