Verified in Android R10.3.1.

 

The u-boot command line is
set bootargs 'console=ttymxc0 init=/init androidboot.console=ttymxc0 gpu_nommu,gpu_memory=32M video=mxcdi0fb:RGB24,800x480M@60,int_clk video=mxcdi1fb:YUV444,TV-NTSC tve'

 

After android bootup, in console, input command
echo 0 > /sys/class/graphics/fb1/blank
setprop rw.SECOND_DISPLAY_CONNECTED 1

 

Click usb mouse, can see Adroid UI in both TV and DVI screen.

When play movie, image will be displayed in TV.
