Addressing for CDMA in PS

I want to set up a CDMA such that when I get certain packets over Ethernet I move them to a BRAM in PL.


I have the CDMA code set up on the ARM of my Zynq, and using that to transfer data works fine sometimes.


However, when I get a packet from ethernet using LWIP, if I take the pointer to the payload of the received message, it is some high address, like 0xEA000025.


The CDMA is connected to the HP port on my ARM, but that only gives it access to 0x00000000-0x3FFFFFFF.

Is the address 0xEA000025 correct, or do I need some kind of translation to get the correct physical memory address?
