DMA decode error

I am trying to connect a DMA to a custom IP block via the AXI Stream Interface. 

I have connected the M_AXI_MM2S and the M_AXI_S2MM ports of the DMA to the S_AXI_HPC0_FPD port of the Zynq uLtrascale+ ( We are using a ZCU 102).

However when I try to stream data via the interface the DMA runs into an error - DMA decode error as it has a wrong source address.

Does it have anything to do with the HPC0 port because the same address was able to transfer data when connected to the HP0 port.

Couls someone point me in the right direction?

Thanks
