Hi all,

I'm using imx6solo android 4.4.3, i configure dual display lcd and hdmi. i'm using RGB666 lcd. Bootargs below i mentioned.

BOARD_KERNEL_CMDLINE := console=ttymxc0,115200 vmalloc=400M init=/init video=mxcfb0:dev=lcd,CLAA-WVGA,if=RGB666 video=mxcfb1:dev=hdmi,1920x1080M@60,if=RGB24 video=mxcfb2:off video=mxcfb3:off fbmem=5M,28M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=384M

i am getting LCD as proper but HDMI as RGB mixed without Red. And also only one frame buffer(fb0-lcd) is created.

How to create one more frame buffer for HDMI???

How to fix this issue??

Regards,

Aravinth
