各位好:

      我现在在搞一个uboot logo的问题,使用的是mipi屏,参考了Patch to support uboot logo keep from uboot to kernel for NXP Linux and Android BSP (HDMI, LCD and L...  这个补丁,但是连uboot的红绿蓝都没有。之前在其他项目搞的lvds屏打上这个补丁之后还能出现红绿蓝,现在开机还是黑屏,请问这个包不支持mipi屏吗?有没有支持mipi屏显示uboot logo的patch?多谢各位!

在mx6sabre_common.h 文件中选择了 IPU_OUTPUT_MODE_LCD 的输出模式,开机uboot没有什么变化,还是黑屏。

I think you need to add the mipi dsi support in u-boot first.

Thanks for your answer:

I have tried this patch, the version is too old, the mx6q_sabresd.c file in the first patch is not available, now I am using the 2015 version of Uboot.I gave it a try and this patch is available on UBoot2009.Is there any updated patch?

In the new version of u-boot source code, there is mx6sabresd.c.

Thank you so much for your replay:

   Yes, I know this one. I manually modified it according to the patch. Except for the first patch, all the other patches have been modified.There are a lot of differences between the old version of the code and the new version of the MXSabresD.c code, and I don't know exactly where to put the modified code.The LCD_enable function is also unavailable. Do you have a simple instruction manual for the application of this patch on the new version of Uboot? looking forward for your replay.
