Carmel (MAXREFDES18#) ZedBoard Quick Start Guide

15. Setup of the terminal program to run on the PC using the following steps. Before

loading the executable firmware file on the FPGA, the terminal program on the

PC should be running. The example firmware running on the FPGA

communicates with the PC via a USB port set up to emulate a serial port (UART).

To establish this communication link, the PC must be configured with the

appropriate Windows drivers. A suitable terminal program such as Tera Term or

HyperTerminal should be invoked.

The ZedBoard utilizes the Cypress USB-UART bridge IC. If the Windows cannot

automatically install the driver for the Cypress USB-UART bridge IC, the driver is

available for download from www.cypress.com/?rID=63794. The driver is WHQL

certified for the default Cypress VID / PID of 0x04B4 / 0x0008.

Once installed, Windows will assign a previously unused COM port. Use the

Windows Control Panel | System | Device Manager to determine the COM port

number. (It will be named Cypress Serial.) Make a note of which COM port this

is. That information is needed in the next step.

Next, a terminal emulation program needs to be installed and launched. For

Windows XP® and earlier systems, the HyperTerminal program is the usual

choice. However, since HyperTerminal was eliminated from Windows 7, it may

be necessary to locate an alternative. Several are available; one good choice is

called Tera Term (http://ttssh2.sourceforge.jp/). Whatever terminal program you

choose, the communication should be set up by opening the COM port number

previously described above and the port configured as:

bits per second: 460,800;

data bits: 8;

parity: none;

stop bits: 1;

flow control: none.
