The //Digilent JTAG-HS3// adapter serves as programming header for //Xilinx// FPGAs and SoCs.

===== Driver =====
Depending on the application which uses the adapter under //Windows 10//, you have to install and choose the driver. To do this, you need local administrator rights.
\\ 
At the OST we use: 
  * **JTSG-HS3 FTDI CDM driver**: To access the SOC with //Vivado// 
  * **JTAG-HS3 WinUSB driver**: To access with //OpenOCD (eclipse)//

==== Using a OST Computer ====
Regular students don't hava admin rights. Therefore, the OST //Windows 10// image contains a driver switch tool. It can be found under

''Start'' → ''Informatik''

after this choose among the two

==== Using a Private Computer ====
To switch drivers on a computer with local admin rights we suggest using the [[https://visualgdb.com/UsbDriverTool/|SysProgs USB Driver Tool]]. 
  - Download the [[http://visualgdb.com/UsbDriverTool/|USB driver tool]], extract and run it.
  - Connect your FT2232 based programmer, e.g. the JTAG-HS3. If you use the Zybo board, connect the board directly as it has the programmer already packed on the board.
  - Identify the USB serial converter, which connects to the JTAG bus. Depending on your actual board this will be
    * Avnet MicroZed: Device name: Digilent USB Device, Vendor ID = 0403, Device ID = 6014  \\ {{:embedded_systems:jtaghs3:usbdrivertool.png?400|}}
    * Digilent Zybo: Device name: USB Serial Converter A, Vendor ID = 0403, Device ID = 6010, Interface = 00 \\ {{:embedded_systems:jtaghs3:installwinusbdriver.png?500|}}
  - Right-click on the device and select the WinUSB driver to install the driver 
  - If you want to reinstall the default driver choose //Restore default driver// or //Install FTDI CDM//.
