Remove transmit chain from ADRV9009 Design

Hi,

I am not using the transmit chain in the adrv9009/zcu102 reference design. What steps should i follow to safely remove the chain and free up FPGA resources?

Thanks,

Andy

    Hi Andy,

    Remove all IPs from the Tx path starting from the DMA untill the jesd_link.
    Similar thread on removing the Rx and using Tx.

  • Hi Andrei,

    Thanks for your response. A couple of clarifications:

    1) So in the block diagram within Vivado I can remove the axi_hp3_interconnect and the tx_adrv9009_tpl_core and all blocks in between these?

    2) I think i then need to remove the corresponding blocks in /linux-xlnx/arch/arm64/boot/dts/xilinx/zynqmp-zcu102-rev10-adrv9009.dts? Do i need to do anything with /linux-xlnx/arch/arm64/boot/dts/xilinx/adi-adrv9009.dtsi or any other files?

    3) Will the scope on IIO_Oscilloscope still work?

    Thanks

    ADRV9009 without TX is effectively a ADRV9008-1.

    Please use this device tree instead:

    https://github.com/analogdevicesinc/linux/blob/master/arch/arm64/boot/dts/xilinx/zynqmp-zcu102-rev10-adrv9008-1.dts

    OSC will still work.

  • Hi

    This does not seem to work.

    I opened the block diagram in vivado and removed the dma to the jesd link. I also replaced zynqmp-zcu102-rev10-adrv9009.dts for zcu102-rev10-adrv9008-1. All builds fine, but when the kernel starts it hangs (see below). Any ideas?
