In the last week I've been trying to get the same process to work to build the eglfs backend for Qt5 for the karo TRITON-TX6DL. In all attempts, the X server or the egl backend have failed to start when invoking a Qt application such as qmlscene. Running eglfs results in a segfault and attempting to open any of the applications in the X11 backend build of the Qt5 based demo results in a GL error with no useful debug output, even after setting the debug environment variable for Qt. I have tried following the steps here: http://wiki.wandboard.org/index.php/Building_Qt5_using_yocto_on_Wandboard and this gets me the closest to a working environment for the board - it just means the eglfs graphics won't work for graphical apps. The rest of Qt seems to be fine. Also, the recent master build of yocto doesn't work at all since the patched ka-ro kernel that I've been using is 3.16 and this is not compatible with gcc5. What am I to do since I don't know which commits to cherry pick in order to get the recent changes that might fix the problem. Searching for other similar problems potentially experienced by other users resulted in this: http://stackoverflow.com/questions/20020898/qt-on-i-mx6-with-platform-eglfs-segmentation-fault This appears to be related to the binaries required by the galcore kernel driver. Does anyone have any ideas? Thankyou
