No, we need a boot script, because this is the way we boot our openSUSE images (we boot with an initrd and some special bootargs).

I cannot find where fdtfile is defined. Could you point me, please?
I only found it for XU3 version. Not for U3/X2 version.
Maybe, it is in DFU infos? If so, how to get fdtfile info, so that we can boot from our bootscript?

No, we use zImage + DTB + initrd from a bootscript.
