Yes always write the .sdcard file to my sdcard and boot from this. To be honest i don’t know what i can do otherwise.
Btw how can i define the size of the rootfs , so to have more space available? Right now i always did a resize of the partition afterwards,
but somehow i must be able to give the size of the roots including free space.

Yes that is right, but i need qt 5.3.1 which actually is the latest stable release of qt and meta-qt5 does support this only with master branch and there they use streamer 1.0 which is not in daisy, at least i got compile errors when mixing daisy and meta-qt5 master.
But as i saw in other messages here imx6q-sabresd-ldo.dtb will be used for now. I will pull next week and see if it works.
Best regards,
