3.3.7 LVDS/eDP Slot
Similarly to HDMI and DP interfaces, the Qseven
interfaces, LVDS and two embedded Display Ports (eDP) sharing the same pins.
This means that it is possible to have Qseven
interfaces. For this reason, these two interfaces on the CQ7-A30 carrier board are not directly carried tout to specific LVDS or eDP
connectors.
Instead, they are directly routed to an internal slot (PCI-e x8 type), so that it is possible to connect an additional expansion module for the implementation of the
desired video interface (VA64 module, it is included in the "Cross Platform Development Kit 2.0". Please check par. 4.1 for further details).
On the same connector, are also routed the signals, coming from the Qseven
Please remember that CN20 uses a PCI-e x8 connector, but it is used to carry out LVDS/eDP interface, it is not used to realise a PCI-e interface.
The compatibility with PCI-e add-on cards is only mechanical.
