Hi Guys,

 

form the fsl-image-qt5 rootfs for var-som-mx6,

I'm facing a problem when running QT application like below

 

root@var-som-mx6:/usr/share/qt5/examples# touch/dials/dials --platform linuxfb

This application failed to start because it could not find or load the Qt platform plugin "linuxfb".

Available platform plugins are: eglfs, minimal, minimalegl, offscreen.

Reinstalling the application may fix this problem.

Aborted

 

I added linuxfb & xcb on my local.conf and bitbaking again but still facing the same error..

 

it is /etc/profile.d/tslib.sh

export TSLIB_TSDEVICE=/dev/input/touchscreen0

export TSLIB_CALIBFILE=/etc/pointercal

export TSLIB_CONFFILE=/etc/ts.conf

export QT_QPA_GENERIC_PLUGINS=tslib:/dev/input/event0

export QT_QPA_EGLFS_PHYSICAL_HEIGHT=480

export QT_QPA_EGLFS_PHYSICAL_WIDTH=800

export QT_QPA_EGLFS_HEIGHT=480

export QT_QPA_EGLFS_WIDTH=800

export QT_EGLFS_IMX6_NO_FB_MULTI_BUFFER=1

export QT_QPA_EGLFS_DEPTH=24

export QT_QPA_PLATFORM=linuxfb:fb=/dev/fb0:size=800x480:mmSize=800x480

 

and please refer to my local.conf below.. thanks..
