Cannot Work on ZYBO-Z7-20

[JeremieMelo]

I want to run this project on ZYBO-Z7-20. I think the only difference from ZYBO is the PS part in block design.
I simply change the board in settings from ZYBO to ZYBO-Z7-20 and successfully generate bitstream. I build u-boot.elf by using the latest u-boot-digilent repo (I set it to boot from SD casrd). And I build uImage based on the latest linux-digilent repo.
I also build devicetree.dtb by using the zynq_zybo.dts offered in this repo. The modification is bootargs, I set it to boot from SD card.
It just give error like:

I need help on this situation.
