Linux/AM5728: GUI application on HDMI

Hello,

I checked the website and I found this 

So where should changed.

I tried add this to the am57xx-evm-common.dtsi.

 

However,it accured a problem.

Is that means that I changed the wrong file?

Which Linux SDK is this?
In latest TI SDK the HDMI is already enabled, see am57xx0beagle-x15-common.dtsi:

aliases {
rtc0 = &mcp_rtc;
rtc1 = &tps659038_rtc;
rtc2 = &rtc;
display0 = &hdmi0;

sound0 = &sound0;
sound1 = &hdmi;
};


hdmi0: connector {
compatible = "hdmi-connector";
label = "hdmi";

type = "a";

port {
hdmi_connector_in: endpoint {
remote-endpoint = <&tpd12s015_out>;
};
};
};

tpd12s015: encoder {
compatible = "ti,tpd12s015";

ports {
#address-cells = <1>;
#size-cells = <0>;

port@0 {
reg = <0>;

tpd12s015_in: endpoint {
remote-endpoint = <&hdmi_out>;
};
};

port@1 {
reg = <1>;

tpd12s015_out: endpoint {
remote-endpoint = <&hdmi_connector_in>;
};
};
};
};

&dss {
status = "ok";

vdda_video-supply = <&ldoln_reg>;
};

&hdmi {
status = "ok";
vdda-supply = <&ldo4_reg>;

port {
hdmi_out: endpoint {
remote-endpoint = <&tpd12s015_in>;
};
};
};

In addition you can see this guide for information how to switch between displays in user space:

Hello,
I used the 4.1 sdk.
And could u tell me whether the dual-camera-demo can show the UI application to the HDMI by changing the dts?
Or maybe I should change the code to meet my needs.
Thanks&regardds!

Hello,
Could u give the kmscube demo source?
Thanks&regards!
