Thanks Jonathon! I want to send some data block to radio. I need to use uhd on arm and send the data. now I want to put the data block on ps memory, and access the data block in pl, so I can send the data block in PL direct!
can I setup my own datamover on another HP AXI port under uhd fpga framework? I use uhd-003012,no rfnoc. Thanks again!

Yes, but you should leave that one alone and setup your own datamover on another HP AXI port. What do you want to accomplish?
