What is not covering full application?

You can change the resolution at boot time by setting kernel bootargs/optargs and then re-boot the board.

=> setenv optargs video=HDMI-A-1:1280x720
=> saveenv

We always recommend to use the latest Processor SDK. You are on 3 versions old PLSDK. In this version of SDK, the default QT QPA is eglfs_kms. To fallback to the standard single-screen eglfs plugin, issue the following instruction at the command line or add the same at the QT environment configuration file qt_env.sh at /etc/profile.d. In PLSDK 4.3, default QT QPA is set to eglfs.

export QT_QPA_EGLFS_INTEGRATION=none

Please migrate to latest Processor SDK for further progress on your work.

Hello Manisha,

I tried export QT_QPA_EGLFS_INTEGRATION=none
after that i am getting

PVR:(Error): WSEGL_CreateWindowDrawable: Couldn't set CRTC: Invalid argument [0, ]

I tried latest version (ti-processor-sdk-linux-am335x-evm-04.03.00.05-Linux-x86-Install.bin)
but issue is same

Hi Rahul,

I just tried steps mentioned in this wiki page on BBB with Processor SDK 4.3 release and the QT quick animation applications works well at my end. Are you working on out of box SDK software with BBB or are their any changes to your setup compared to what I tested at my end?
