Linux/AM5728: Running Qt application without Weston

Hiren Gohel

Part Number: AM5728

Tool/software: Linux

Hi Sir,

I am using custom AM5728 board and i want to run QT application without weston or matrix. It is possible to run QT application on weston and matrix. When i stop both weston and matrix the QT application gives segmentation fault.

Why is that?

Is it possible to run QT application without weston and matrix?

Thanks,

Hiren

Hello,

The QT5 in PSDK is prebuilt with Wayland enabled and therefore wayland-egl is the default QPA. In this case weston should running.

If you want QT application without Weston(weston stop), you can use “- platform” option to specify the desired QPA for exmaple eglfs.

Please check this guide for more information:

Hi,

Thanks for reply.

I have read the document. Do you have any test cases or any examples?

Since i am new to this i am not able to understand how to use platform.

Thanks & Regards,

Hiren

Hello,

" To run QT application without Weston, the user can use “- platform” option to specify the desired QPA as “linuxfb” or “eglfs". "
Something like this should work for exmaple(weston must be stop):
./demo -platform eglfs
