rk3288 dual

james09

[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

which SDK did you use? the default one? or the PAD one?

james09

I tested both. default one doesn't work like that.
and pad one is working lcd and hdmi. but pad one detects just one display in android so I cant use Presentation class.

the sdk of PAD do support dual display ,you need fix this issue by yourself
And we suggest you to use more newer version of sdk ,
