HI:

         I am doing the dual port lvds display!  The lvds0 and lvds1 all connected the one lvds panel.It is also dual channel lvds connection to driver  one panel

         My boot parameter is as follows:console=ttymxc0,115200 video=mxcfb0:dev=ldb,LDB-T13,if=RGB24,bpp=16 ldb=dul0 ip=dhcp root=/dev/mmcblk0p1 rootwait  

         I have tried the ldb=spl0 parameters,But the panel cann't display anything.

         I used the ldb=dul1 parameters and it can display the image.But it can only display a half picture.5.jpg

     The normal picture is as follows:
