Hi Jason, Yes you can have two. It will require some hand editing of files. The DmaFIFO connects to the DRAM via an AXI interconnect (x300/ip/axi_intercon_2x64_128_bd/axi_intercon_2x64_128_bd.bd) in x300_core.v. You will need to edit the BD to add more ports to the interconnect. N3xx has a 4x example you could look at in the n3xx/ip directory. You'll also need to edit x300_core.v to add the DmaFIFO instantiation and you should increment NUM_IO_CE. Finally, make sure to assign a separate DRAM address range to each DmaFIFO (via settings regs).
