Hello

 

I am trying to build embedded Linux that runs QtWebengine via Buildroot.

 

I applied a patch at this link to enable webengine on buildroot

 

I enable imx-gpu-viv library, openGL support and eglfs support. to test both webengine and gpu, I run demobrowser with -platform eglfs from QT. It gives me "Could not open egl display"

when I run demobrowser - platform directfb, application occupies half of CPU so GPU does not work and I cant use demobrowser.

 

which library is or configuration is missing?
