i.mx6 non standard LVDS display problem

[andreykononov]

i have LVDS display with 1280x480 resolution and when i trying to show some data on it (video or some app) i can see only 4/5 of data and 1/5 part of screen is black. I'm using linux from yocto jethro. This problem is not depend from kernel cmd, now i have

video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24 video=mxcfb1:dev=ldb,1280x480M,if=RGB666,ldb=di1 ip=none

but when i set other cmd, for example

video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24 video=mxcfb1:dev=ldb,1920x1080M,if=RGB666,ldb=di1 ip=none

nothing changed.

Can i change this situation by make some settings or make change in kernel?

Hi,

    Please try to adjust IPU clock source ! see following link :

It should be helpful for you!
