Supporting hardware debugging requires the platform to support several IP components, most notably the Debug Bridge. Talk to your platform designer to determine if these components are included in the target platform. If a Xilinx platform is used, debug availability can be verified using the platforminfo utility to query the platform. Debug capabilities are listed under the chipscope_debug objects.

For example, to query the a platform for hardware debug support, the following platforminfo command can be used:

$ platforminfo --json="hardwarePlatform.extensions.chipscope_debug" xilinx_u200_xdma_201830_2
{
    "debug_networks": {
        "user": {
            "name": "User Debug Network",
            "pcie_pf": "1",
            "bar_number": "0",
            "axi_baseaddr": "0x000C0000",
            "supports_jtag_fallback": "false",
            "supports_microblaze_debug": "true",
            "is_user_visible": "true"
        },
        "mgmt": {
            "name": "Management Debug Network",
            "pcie_pf": "0",
            "bar_number": "0",
            "axi_baseaddr": "0x001C0000",
            "supports_jtag_fallback": "true",
            "supports_microblaze_debug": "true",
            "is_user_visible": "false"
        }
    }
}

The response shows that the target platform contains user and mgmt debug networks, supports debugging a MicroBlaze™ processor, and also supports JTAG fallback for the Management Debug Network.
