Unsolved i.MX6SL + Buildroot; issues in getting graphics acceleration working
-
Hi,
I'm working on i.MX6 SoloLite Evaluation Kit, my SW environment is Buildroot 2017.02.
I'm trying to get graphics acceleration working on this setup, but the screen stays blank (black) and I'm seeing the following error message on trace log: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"
qt.qpa.egldeviceintegration: Using EGL device integration "eglfs_viv"
QEGLPlatformContext: Failed to create context: 3005
EGLFS: Failed to create compositing context
AbortedAs far as I understand, the plugin is the correct one (eglfs), and the i.MX GPU Vivante is also working correctly. But something is obviously missing/wrong. Some configuration parameter still needs adjusting...?
Thanks for any hint or advice you might have that would fix the issue!

Actually, here's the trace output (some lines were missing):
