Part Number:DRA75

Hi there,

I want to run Qt app on Android Oreo on DRA 756 board on Android A15.

So, I have 2 displays connected i.e one is LCD and other HDMI. I want Android HMI to be run on LCD which is  fine.

But, the qp app always runs on the same LCD screen always.

So I need help on how to run Qt app only on the HDMI display in a presentation mode. I have 3 vdrm connectors already connected to /dev/dri/cardXx.

1) Should i configure the vdrm controllers in qt app somewhere in qt qpa?

2)Should I enable presentation mode for qt apk using android java code?

3) Is there any other way?

Please help.

Regards,

Ronak.
