i.MX6 Android Framebuffer Config for 16bit

I use a i.MX6Q SabreSD to test the framebuffer.

I want to make a config that:

HDMI output @ 1280*720P - bpp=32bit

and a dummy output @ 480*800 - bpp=16bit(I only want to use the frame buffer content, to copy to outsie devices as projector ).

 

But whatever I config via command line or board***.c, the frame buffer color depth for the dummy device(ldb or lcd) always be 32bit(RGBA?)

 

How can I config it?

 

Best regards.
