Dear all:

I use IMX6Q board and want  to enable the Uboot splash screen on the uboot.

I want to enable the Uboot splash screen on the uboot, so I will check the 4 pairs LVDS data signals,1 pair clock,and LCD's power supply.

Also,I will turn on the CONFIG_LCD,CONFIG_SPLASH_SCREEN, and CONFIG_VIDEO_MX5 on the u-boot.

I will check the following steps.

First, Check whether the boost converter can offer the panel's power.

Second,Check whether the IPU and Framebuffer settings are right.These include panel's resolution and panel's pixel clock.

Third,Check whether the LDB, and LVDS clock output correctly.

Finally,Check whether the panel can ouput the splash picture correctly.

Do you have any precise idea to enable the LVDS display panel on the uboot?

Do you have any steps to check whether the processes are right?

Best Regards,

Justin Wu

Please check board/freescale/mx6qsabrelite/mx6qsabrelite.c in the mainline U-boot (2013.04), as it supports LVDS splashscreen by default.
