AD9122 on zynq ultrascale


I want to move my zynq7 design with a AD9122 to zynq ultrascale+. I already recognized, that there is only oserdese2 available and changed that to oserdese3. What else do I need to do? I have also the problem, that I cannot read from the version register of that axi_ad9122 core other cores working fine. But on that i read only 0xdeaddead.
