I'm working on iMX6 SoloLite Evaluation board MCIMX6SLEVK + display MCIMX28LCD.

My SW environment is Buildroot 2017.02 with QT5 Webkit kiosk.

I am trying to get graphics acceleration (eglfs) working on my HW. I have done several experiments but no luck so far.

Basically I am trying to set the correct combination of config parameters in menuconfig.

I am able to start the Webkit browser with "linuxfb" plugin (command line option -platform linuxfb:fb=/dev/fb0), the web page opens up ok. But when trying to start the browser with "eglfs" plugin (-platform eglfs), it fails.

Currently the error message on terminal indicates following:


qt.qpa.egldeviceintegration: EGL device integration plugin keys: ("eglfs_viv")
qt.qpa.egldeviceintegration: EGL device integration plugin keys (sorted): ("eglfs_viv")
qt.qpa.egldeviceintegration: Trying to load device EGL integration "eglfs_viv"

Thanks for any hint or advice you might have!
