Hello,
We have been working on to run qt 5 on i.MX 6 Solo X board. While running QT application,
We set following environment variable.
export QT_QPA_EGLFS_FB=/dev/fb0
export FB_FRAMEBUFFER_0=/dev/fb0
export QT_EGLFS_IMX6_NO_FB_MULTI_BUFFER=1
export QT_QPA_EGLFS_FORCEVSYNC=1
export QT_QPA_PLATFORM=eglfs
We see following error.
/opt/QT_App -platform eglfs
QEglFSVivIntegration will set environment variable FB_MULTI_BUFFER=2 to enable double buffering and vsync.
If this is not desired, you can override this via: export QT_EGLFS_IMX6_NO_FB_MULTI_BUFFER=1

After debugging further, we understand that /dev/galcore node is required which is not being created in our case.
We have enabled following things in kernel config,
CONFIG_DRM_VIVANTE=y
CONFIG_DRM_BRIDGE=y
CONFIG_MXC_IPU=y
CONFIG_MXC_IPU_V3=y
CONFIG_MXC_IPU_V3_PRG=y
CONFIG_MXC_IPU_V3_PRE=y
CONFIG_MXC_GPU_VIV=y
We have also verified that meta-freescale layer has udev entries for galcore device node.
Can anyone point out what can be the issue ?
