Unable To run QML Application on Ti Processor(AM335x based) custom board

Rahul Chauhan

I am not able to run Qt/QML application without specify platform why?
if i am running application
./app
Failed to create display (No such file or directory)
if i am running application like
./app -platform linuxfb
application is working fine .
for this issue i can export QT_QPA_PLATFORM=<platform>
but i don't want to do this manually.
due to this i am not able to run the application remotely via qt creator on target board.

2.only able to run Qt application with platform linuxfb.

I am not able to run qml application with platform eglfs.
