EGLFS Platform Plugin Display is inverted both in X and Y axis



  • Hi,

    I have an embedded system where I ported QT5.4. My custom SoC provides an opengl library that supports OpenGLES 2.0. I've created a folder under mkspecs/device (copied the linux-rasp-pi-g++ folder) and updated the hooks file to add the opengl driver specific initialization code.

    When I run my test using -platform eglfs, the graphics gets displayed but the x and y axis are inverted. Running the linuxfb platform plugin produces a correct image on the screen.

    I'm running on a 3.10 Linux kernel and my gcc compiler is 4.9.

    I don't know what else I can change from my plugin to make the image upright. Any help would be appreciated. I'm a newbie here so forgive me if I omitted some critical info.



  • That's weird. Have you verified the behavior with any non-Qt-based GL apps?
