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/blankmkdir -p /run/user/root
chmod 0700 /run/user/rootexport XDG_RUNTIME_DIR=/run/user/root
export HOME=/home/root
export XDG_CONFIG_HOME=$HOME
export QT_QPA_PLATFORM=waylandopenvt.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.
Hi Carlos,
I have checked the color formats and fb, everything is properly set. Unfortunately none of the links helped me out.
Any other hint? I can assume is a wayland weston artifact.
Best regards.
Hi,
You need to ensure that the color formats of frame buffers are compatible, and configured to the proper resolution. Additionally, you could take a look at the following links:
