Dual display problem on fsl-yocto-L4.9.11

Hi,

 

I am using a SabreSD with dual display: LCD + HDMI

 

The software I use is the latest NXP Yocto BSP fsl-yocto-L4.9.11_1.0.0, specifically the image core-image-weston, DISTRO fsl-imx-wayland. I have modified the Uboot environment as follows:

 

      $ setenv mmcargs 'setenv bootargs console=${console},${baudrate} ${smp} root=${mmcroot} video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24 video=mxcfb1:dev=lcd,if=RGB565 '

 

When I start my multi display script, an area of the secondary display is blued. It is the same if the displays are arrange in the opposite order. You can see it into the pictures attached.

 

# Script which starts multi display

 

echo 0 > /sys/class/graphics/fb0/blank
echo 0 > /sys/class/graphics/fb2/blank

 

mkdir -p /run/user/root
chmod 0700 /run/user/root

 

export XDG_RUNTIME_DIR=/run/user/root
export HOME=/home/root
export XDG_CONFIG_HOME=$HOME
export QT_QPA_PLATFORM=wayland

 

openvt.kbd -s -- weston --log=/dev/console --device=/dev/fb0,/dev/fb2 --use-g2d=1 --idle-time=0

 

If I connect a mouse, when I move it over the blue are the desktop is redraw, but the mouse pointer is invisible.

 

Could you help me with this?

 

Best regards.
