Hardware support 2 LVDS Display, BSP support them adaptively. But one of them flicker in Linux kernel stage. If reboot through reboot cmd(WDOG1), it will not flicker.


I suspect that this is consistence issue which generate by U-boot/Kernel IPU/Clock settings?



Linux 4.1.15  (Original BSP, not apply any patch)

U-boot 2015.4 (have applied U-boot patch from Patch to support uboot logo keep from uboot to kernel for NXP Linux and Android BSP (HDMI, LCD and LVDS)  ).
