In order to use the dongle-less USB JTAG connections on the zc702/Zed Zynq boards, the Digilent Adept drivers must be installed on the host machine.
Installation
digilent.adept.runtime_2.10.2-x86_64
digilent.adept.utilities_2.1.1-x86_64
libusb1-1.0.8-0.1.el5.x86_64.rpm
Unpack digilent.adept.runtime_2.10.2-x86_64 and cd into directory
Install the runtime libraries
sudo ./install.sh
Install the FTDI device drivers included in the Adept Runtime package
cd ftdi.drivers_1.0.4-x86_64
Unpack digilent.adept.utilities_2.1.1-x86_64 and cd into directory
Install the utilities libraries
sudo ./install.sh
Install the libusb1-1.0.8-0.1.el5.x86_64.rpm package
sudo rpm -ivh libusb1-1.0.8-0.1.el5.x86_64.rpm
Device Connection
Plug in the device usb cable to the host.
Enumerate connected devices by executing:
rdusr108:>djtgcfg enum Found 1 device(s) Device: Zed Product Name: Digilent Zed User Name: Zed Serial Number: 210248451299
Impact and xmd should now find the Digilent plugin and connect to the Zynq devices.
Edit Cable Name
If there are multiple devices with the same name connected to the same host, then assign each board a unique name using the dadutil command.
dadutil setusr -d Zed --usr Zed1
This changes the device name from "Zed" to "Zed1".
XMD Connection
Using the device name from the djtgcfg command, connect via xmd using the xilinx plugin parameters
