Hi Sir,

 

 

We had see LVDS panel output is not correct base on customer MX6Q board some times.

We had use Gray Pattern PNG file and it can see some pixel is not correct.

We try to use memtool to access "IPU_DI0_GENERAL " "IPU_DI0_BS_CLKGEN0" and "IPU_DI0_BS_CLKGEN0" register , but it always hang up.

 

 

OS is Android JB 4.3

Panel setting is 1920x1080p60 splite mode
