This adaptor board allows you to connect a Sharp's LQ043 LCD to your docking board.
The description, the datasheet and the schematics of this adaptor board can be found here.
The following table summarizes the possibilities to connect the LQ043 and the Touchscreen to your development board:

(1) Flat cable
A simple flat cable (PC like) can be used to connect the LQ043_Adapt to the APF27Dev/APF9328DevFull. If you do not have one, a ready to use cable can be found here.
Align the pins 1 (square via) on both boards together.
Do not use long cables.
(2) 4 wires cable
It is a simple one to one 4 wire cables (2.54mm single row headers on both boards: LQ043_adapt and Devfull)
OPOS6ULDev
Default video PLL cannot generate 8,69MHz pixel clock needed by the LCD (too low), so you need to tweek CCM register a little before booting Linux:
