I'm using Yocto Project 2.4 with QT 5.8 and i.MX6 Quad sabreSD platform.
After I build image with no wayland and X11, I tried to run my application with below command.
./Qt5_CinematicExperience -platform eglfsUnfortunately, I had occurred an error like below.
root@imx6qsabresd:/home# Qt5_CinematicExperience -platform eglfs QEglFSVivIntegration will set environment variable FB_MULTI_BUFFER=2 to enable d ouble buffering and vsync. If this is not desired, you can override this via: export QT_EGLFS_IMX6_NO_FB_M ULTI_BUFFER=1 forenex victor ldb diabled LVDS backlight get = 0 ldb_disable(687) forenex victor LVDS ldb->ctrl=[693] ldb_disable(688) forenex victor LVDS ldb->spl_mode=[1] ldb_disable(689) forenex victor LVDS ldb->dual_mode=[0] ldb_disable(690) forenex victor LVDS ldb->ctrl_reg=[8] ldb_disable(703) forenex victor LVDS ldb->ctrl=[688] /mnt/raid/forenex/yocto2.4/build-wayland-q/tmp/work- shared/imx6qsabresd/kernel-s ource/drivers/video/fbdev/mxc/ldb.c_ldb_enable(623) forenex victor LVDS tmp_ctr l=[2b0] /mnt/raid/forenex/yocto2.4/build-wayland-q/tmp/work- shared/imx6qsabresd/kernel-s ource/drivers/video/fbdev/mxc/ldb.c_ldb_enable(658) forenex victor LVDS ldb->ct rl=[2b5] [ 1] Failed to open device: No such file or directory, Try again...

I also export some parameter with below command.
export QT_QPA_EGLFS_FB=/dev/fb0And it still show the same error.
How can I solve this problem?
