About IMX6Q-SDB LVDS proting issue

我只修改了imx6qdl-sabresd.dtsi里的LVDS1的timing参数,并且依照I.MX_BSP_Poring_Guide.pdf

并添加了uboot启动参数: video=mxcfb0:dev=ldb,if=RGB666

启动就会出现这种情况,半边正常半边花屏,网上有说改ldb.c里的ldb_modedb,但是我在drivers/video/fbdev/mxc/ldb.c里找不到该结构体。

 

内核版本:4.1.15_2.0.0_ga

 

i only change the parameter of lvds1`s timing on imx6qdl-sabresd.dtsi,and modify the u-boot parameters according to the I.MX_BSP_Porting_Guide.pdf document.

 

but as you see,my panal can`t work well.

 

kernel:4.1.15_2.0.0_ga.

 

What am I to do?
