[size=11.008px]helloim developing a new board rk3288.
Im trying to dual display with android 4.4
I added a tft lcd(480x800) to lcdc0, and it works good.
and I set lcdc1 to hdmi,  but it doesn't work.
I changed the default lcdc to lcdc1 in hdmi/rk3288/rk3288-hdmi.c, but still doesn't work.
furthermore, when hdmi is on, lcd frequency is changed.
but in android 5.1, it works well.
where do I have to change in the source code?
I want to make it with android 4.4.
please help
thanks
