vivante driver segmentation fault with qt 5.4.2 + qtwayland 5.4.2 + weston 1.6.0

[vikaspatil]

Dear All,

When I launch any example application from (i.e. specific from opengl folder) qt5.4.2 and qtwayland 5.4.2 on desktop-shell of Weston 1.6.0 with GAL2D renderer  from following list I am getting segmentation fault as mentioned below in graphics driver. While I can run other application from “/usr/share/qt5/examples/widget, touch, gui etc…” , . I also tested “weston-simple-egl” test for EGL and GLES2 and it is working fine.

Does anyone here tried this and observed the same? Could someone here give some inputs/suggestions to debug and fix this or any known fix? Should I try 5.0.11.p4.4 instead 5.0.11.p4.5 fro vivante driver?

Hi Vikash,

I am working on sabresd platform, wayland backend and qt5.3.2 using fsl-release-bsp (imx-3.14.28-1.0.0_ga). But I am not successful yet. I have seen some touch anomalies on the screen for qt5 applications. Can you share with me your build procedure. Which repo and branches, patches etc.

Thanks.

Yes. I used older version of GPU driver. i.e. imx-gpu-viv_5.0.11.p4.4-hfp

Hi Rodrigo,

So did this works with older version and not with the new ones?

Thanks! Works for my now.

But instead of Weston I use the QtWaylandCompositor!
