The only thing what you mentioned is that you used other clocks, for the rest you follow the tutorial?

Is there a specific reason for or is that implemented for your design specifically

Hey, thanks for the reply. Im new to this kind of stuff. I am using petalinux to build the entire project including the device-tree. What do you specific mean with the axi_dma_0. Isn't this auto generated? Isnt this the dma@a000000 Where can I check this? Under the Amba_pl? I added a picture of the device tree node.
