Hi Andrey,
Thank you for your guidance, But i Did find any Doc related Yocto or imx-linux-dunfell.
I may be wrong in my search, but I find Docs related to ZEUS and Gatesgarth.
Have a look at this repo:

You can use it as a platform development base, adding layers you need
into the BSP as you go. Default branch in that repo points to Dunfell
branch, so you would start the development on it straight away.

Can I start with anyone of the above but ZEUS is also recently EOL?
I would not recommend to start off Zeus, as it is also EOL.

And I have one doubt regarding meta-printing layer, as per my search its present upto Rocko version
Will I get this support any of the latest Yocto version?
This I do not know, your best bet would be to contact the layer
maintainer to discuss this.

Thanks and regards

I have crated rootfs with Yocto Rocko . I am running Qt application on it with X11 support.
Rocko branch is EOL since already 2,5 years, see

Not sure if there would be any advise or support provided here for
versions that are already pas their EOL.

Have you tried the same setup with either Dunfell or Master?

What I observed booting log :
RandR extension missing
matchbox: Cant find a keycode for keysym 269025056
matchbox: ignoring key shortcut XF86Calendar=!$contacts

matchbox: Cant find a keycode for keysym 2809
matchbox: ignoring key shortcut telephone=!$dates

matchbox: Cant find a keycode for keysym 269025050
matchbox: ignoring key shortcut XF86Start=!matchbox-remote -desktop

And main observation is new rootfs {created with Rocko}is not supporting video playing feature with qt app.
But old rootfs {created with Krogoth} was supporting Video playing.

Did Imissed any Package in rootfs ?
Please guide me for this Solution.

Note : for Both Rootfs I have same Packages mentioned in local.conf
