board: imx6q_sabresd;

version: u-boot-2009.08;

patch:0001-Enable-uboot-logo-for-HDMI-LCD-and-LVDS.patch

 

Dear,

     I want to show logo on my 1280x1024 lcd panel. I have a DVI2RGB board connect to hdmi of mx6q_sabresd. The image shows ok after booting kernel. Now, I need to show logo when system start up. But I found a strange problem when I patch the0001-Enable-uboot-logo-for-HDMI-LCD-and-LVDS.patch to u-boot-2009.08.   HSYNC is always low and DE is not stable. what's the diference between the uboot patch and the kernel?
