Could not open egl display Error on imx6q

  • Hello,

    I cross-compile Qt5 with buildroot-2016.11
    My board is an imx6q from Toradex.

    I have this problem when I want to execute my program:
    QML debugging is enabled. Only use this in a safe environment.
    QEglFSVivIntegration will set environment variable FB_MULTI_BUFFER=2 to enable double buffering and vsync.
    If this is not desired, you can override this via: export QT_EGLFS_IMX6_NO_FB_MULTI_BUFFER=1
    Could not open egl display

    My default graphical platform is eglfs
    On buildroot I selected :

    • open GL support
      - open GL API (OpenGL ES 2.0+)
      - openGL module
    • freescale im.x librairies: imx-gpu-viv

    Before I use buildroot-2014.08 and it works!
    I need some help to resolve this problem!

    Hi and welcome to devnet,

    Did you try to contact the folks from Toradex directly ? They might have more experience with that kind of scenario.
