Hi Haohua,

The lvds(double 8 bit mode ) and hdmi same display on the i.mx6DL can not be realized. Because only one IPU in i.mx6DL, the max resolution is 1080P, the resolution is not enough for dual LVDS and HDMI. Besides, there are two DI, two LVDS use DI0&DI1, so no display port for HDMI.

But if single LVDS, it's easy to realize, one DI to use for HDMI.

Hope this can help you.
Have a great day,
Dan

below is only use hdmi,and display is ok:

setenv bootargs console=ttymxc0,115200 init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32 video=mxcfb2=:off fbmem=10M,10M vmalloc=400M androidboot.console=ttymxc0 androidboot.hardware=freescale

Mx6dl has only one ipu, lvds(double 8 bit mode )need  use di0 and di1 two channel.

I do not know If add hdmi is ok?

I‘ve tested lvds(single 6 bit mode)+hdmi is ok.

thanks.
