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.
...
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.
| Code Block |
|---|
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
| Code Block |
|---|
