Android booting hanged when set lvds7 as video output

Hi guys,

I have the udoo neo full board, and I compiled the android 5.1.1 successfully,

I connect a new lcd with lvds connector(not bought in udoo shop)

when set u-boot using imx6sx-udoo-neo-full-lvds7-m4.dtb(just set video_output=lvds7 in uEnv.txt), the system was hanged on.

But can boot when set u-boot using imx6sx-udoo-neo-full-hdmi-m4.dtb

PS: I did not modify the DTS for ldb driver yet, does it affect the system booting?

Thanks for any suggestions.

FOUND LOG IN log.txt.

The problem you are encountering may be because 'video_output' needs to be set to lvds7 in two different places (/data and /system). See the following for details:

Thanks Bander.

I did not compile Touchscreen driver into the kernel, after I insmoding the TP driver, it passed.
