    Can someone help me out in matching these pins please.

    I have attached the LCD pin outs and UDOO LVDS pin out.

    I can figure out some of the connections but others i am have trouble with like for example does the pins 31 to 39 on the LCD need to be attached to UDOO board and if so were?

    Thank you for any help you can give me.
