Question asked by Kevin Cheng on Dec 1, 2015

Hi,

 

Sometime we power-on the device. LVDS panel is black and no infomation on LVDS panel.

Check the dmesg, there've "MXCFB_WAIT_FOR_VSYNC: timeout" message always repeate.

We've already disable "CONFIG_MX6_CLK_FOR_BOOTUI_TRANS" in kernel , but it seems no help.

Have any method to solve this problem ?  Thanks!!

CPU : imx6Q

Memory : 2GB

Output display : LVDS & HDMI

OS : Android 4.3

Base on BSP: android_jb4.3_1.1.1
