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?

Hi tab

had you changed kernel boot parameter as in examples in

Table 10. Common kernel boot parameters attached Release Notes.

Also may be useful to check links with examples of bring-up of new lvds lcds
