wayland service not starting at boot i.mx6DL

Chandrashekhar_MVE · ‎06-12-2024

Hi

command to build yoctos is:(imx-linux-nanbield -m imx-6.6.3-1.0.0.xml)

DISTRO=fsl-imx-xwayland MACHINE=imx6dlsabresd source imx-setup-release.sh -b build-xwayland
bitbake imx-image-full

We have issue with latest wayland build. weston.service is not started at boot up.

root@KitchenBrains:~# systemctl status weston.service

my weston.ini file shows as below,

[screen-share]
command=/usr/bin/weston --backend=rdp-backend.so --shell=fullscreen-shell.so --no-clients-resize

What exactly need to change in yocto setup to get proper LVDS settings? and also get proper evnvirnoment to set for XDG_RUNTIME_DIR?

Hi @Chandrashekhar_MVE,

Thank you for contacting NXP Support.

First of all, I would like to ask about your board. Are you trying in a custom board or our EVK?
I'm working with a similar error in other board and my research indicates that could be a problem of driver and libraries installation. In your case, if you are using the BSP provided by NXP, could you please try with other BSP version to verify if there is a specific issue with that version?

Have a great day!

Hi Brian,

Did you get any solution to this problem.

Hi @Chandrashekhar_MVE,

Could you please tell me if you are trying to start Weston from the serial terminal or SSH?
If it's the case the problem is related with the session used to start Weston.
I could resolve the issue in my side starting Weston in the display output (the terminal shown in your LVDS display).

Have a great day!

Please share your steps and exports.

Hi ,

This is our custom board. We have only LVDS1 connected in our system . no HDMI & no LVDS0. This issue seems to us something to do with wayland. We are good with psplash screen. Please refer my earlier post.
