    I used both MATLAB R2020b and Vivado 2018.3 to generate BOOT.bin from my customized transceiver for my PackRF. In Set Target Interface (Section 1.3) of the HDL Workflow Advisor in Simulink, I set the following:
    

    * ch1_tx_dma_i as IP Data 0 IN [0:15]
    

    * ch1_tx_dma_q as IP Data 1 IN [0:15]
    

    * ch2_tx_dma_i as IP Data 2 IN [0:15]
    

    * ch2_tx_dma_q as IP Data 3 IN [0:15]
    

    * ch1_rx_dma_i as IP Data 0 OUT [0:15]
    

    * ch1_rx_dma_q as IP Data 1 OUT [0:15]
    

    * ch2_rx_dma_i as IP Data 2 OUT [0:15]
    

    * ch2_rx_dma_q as IP Data 3 OUT [0:15]
    

    When I turn on PackRF with customized BOOT.bin, what will be the locations and addresses of these IQ DMAs?

      DMA memory locations are defined in the device tree. Here is the base address for the RX DMAs: https://github.com/analogdevicesinc/linux/blob/d7c0f7cad3280fdcff25a20443ad82487f2d3921/arch/arm/boot/dts/zynq-adrv9361-z7035.dtsi#L140
      

      This may be different for your board based on the software version. I would decompile and check the running device tree from your system's BOOT partition. These will match the offset addresses in Vivado.

          From the dts file, it seems that Line 751 is for the RX while Line 773 is for the TX. Both specify Channel 0. What are the address offsets for Channel 1 Q, Channel 2 I and Channel 2 Q?
