Hi Community,

I'm working on i.MX6 Quad sabre-SD cpu and build Android 6 as my image.

According the booting process, it will show little penguin in u-boot and little android in kernel then big Android in Android system.

 

What I have faced the issue is when I plugin power panel will flash once and then show little penguin.

And when little Android turn into big Android log panel will flash once too.

The flash issued video is enclosed below.

And the flash waveform is enclosed too.

 

According to my customize u-boot , I modified bootload/bootloader/u-boot/board/freescale/FX100/FX100.c

In FX100.c code I will set my LVDS power enable in function enable_lvds().

Then I enable LVDS backlight and pwm in function board_late_init().

Is there any problem in my design?

 

In this case, how can I solve this issue?
