4.1.2 eDP working mode
®
If the Qseven
module used with CQ7-A30 carrier board offers support for eDP displays (up to two interfaces), then it is necessary to plug the adapter module in
LVDS/eDP slot using the adapter's dedicated edge connector CN9.
In this case, only the module's connectors CN5, CN6, CN7 and CN8 will be usable.
Moreover, it is possible to use two separated 30-pins or 40-pins connectors for the connection of the eDP displays. All the connectors are VESA
connectors for Display Port interface.

is the signal used for Backlight enabling, is the logical conjunction (i.e. AND) of the signal eDP_BLEN
eDP_BACKLIGHT_EN
(LVDS_BLEN on CQ7-A30 carrier board's connector CN20) and the signal PLT_RST#. This has been done so that at each reset of the module, the eventually
connected backlight and display will also turn off themselves.

Selection of the suitable connector for each eDP interface is made using jumpers JP5 and JP6,
which are two standard pin header, P2.54mm, 1x2 pin.
