Embedded Graphics Driver can't detect LVDS panel EDID.

I am building an XPDM windows 10.3.1 embedded driver (IEGD) for 915GMS chipset (downloaded from here:http://www.intel.com/p/en_US/embedded/hwsw/software/iegd# download http://www.intel.com/p/en_US/embedded/hwsw/software/iegd# download)

it seems the driver catches my LVDS LCD parameters well, but when it comes to display detection in windows it gives "non PnP" displays for some reason.

Graphics and panel work well. But no automatic detection and no backlight brightness tuning is possible.

I am using standard preconfigured profile for non-EDID mode.

Where am I wrong?

Hello,

I suggest you to refer to the following site to get to the appropriate channel of support on these products:

Actually, we didn't purchase Intel's Premier Support yet, because it's not our profile somehow. CADs, physics, solid design, yes. But no connections with Intel yet.

That's why I am asking on open discussion forum.
