Fresno (MAXREFDES11#) ZedBoard Quick Start Guide

1. Required Equipment

• PC with Windows® OS with Xilinx® ISE®/SDK version 14.2 or later and two USB
ports (Refer to Xilinx AR# 51895 if you installed ISE WebPACKTM design
software on your PC.)

• License for Xilinx EDK/SDK version 14.2 or later (free WebPACK license is OK)

• Fresno (MAXREFDES11#) board

• ZedBoardTM development kit

• Industrial sensor or signal source

2. Overview

Below is a high-level overview of the steps required to quickly get the Fresno design
running by downloading and running the FPGA project. Detailed instructions for each
step are provided in the following pages. The Fresno (MAXREFDES11#) subsystem
reference design will be referred to as Fresno throughout this document.

1) Connect the Fresno board to the JA1 port of a ZedBoard as shown in Figure 1
Ensure the connector is aligned as shown in

2) Download the latest RD11V01_00.ZIP file located at the Fresno page.

3) Extract the RD11V01_00.ZIP file to a directory on your PC.

4) Open the Xilinx SDK.

5) Download the bitstream (.BIT) file to the board. This bitstream contains the FPGA
hardware design and software bootloader.

6) Use Xilinx SDK to download and run the executable file (.ELF) on one of the two
ARM® CortexTM -A9 processors.

3. Included Files

The top level of the hardware design is a Xilinx PlanAhead Project (.PRR) for Xilinx
PlanAhead version 14.2. The Verilog-based arm_system_stub.v module provides
FPGA/board net connectivity and instantiates the wrapper that carries both the Zynq
Processing System and AXI_MAX11100 custom IP core that interface to the Pmod port.
This is supplied as a Xilinx software development kit (SDK) project that includes a
demonstration software application to evaluate the Fresno subsystem reference design.
The lower level c-code driver routines are portable to the user’s own software project.

4. Procedure

1. Connect the Fresno board to the JA1 port of a ZedBoard as shown in Figure 1.

2. Power up the ZedBoard by sliding the SW8 switch on the ZedBoard to the ON
position.

3. Download the latest RD11V01_00.ZIP file at

www.maximintegrated.com/AN5563. A ll fil es av ail abl e for download are

available at the bottom of the page.

4. Extract the RD11V01_00.ZIP file to a directory on your PC. The location is
arbitrary but the maximum path length limitation in Windows (260 characters)
should not be exceeded.

In addition, the Xilinx tools require the path to not contain any spaces.

C:\Do Not Use Spaces In The Path\RD11V01_00.ZIP

(This path has spaces.)

For the purposes of this document, it will be C:\designs\maxim\RD11V01_00\.
See Appendix A: Project Structure and Key Filenames in this document for
the project structure and key filenames.

5. Open the Xilinx Software Development Kit (SDK) from the Windows Start
menu.

6. SDK will prompt for a workspace directory, which is the location where the
software project is located. For this example, it is:

C:\designs\maxim\RD11V01_00\RD11_ZED_V01_00\Design_Files\top.sdk\SDK\SD
K_Export

Click OK and SDK will open. The Xilinx SDK is based on an Eclipse™-based
IDE, so it will be a familiar flow for many software developers.

7

Fresno (MAXREFDES11#) ZedBoard Quick Start Guide

7. Review the SDK IDE. The Project Explorer in the upper left tab should have
three components as shown in the image below. If all three subfolders are
present, you can skip the next step.

8

Fresno (MAXREFDES11#) ZedBoard Quick Start Guide

8. If the Project Explorer does not contain these three subfolders, launch the

File | Import menu, expand the General folder, and select Existing Projects
into Workspace. Click Next. Set the root directory to:

C:\designs\maxim\RD11V01_00\RD11_ZED_V01_00\Design_Files\top.sdk\SDK\SDK_Export

and the missing projects should appear in SDK Project Explorer with their
checkboxes checked.

Click Finish to import the projects.

9

9. To download the bitstream (.BIT) file to the board, click on the Program FPGA
icon (which looks like a green chain of devices).

The Program FPGA dialog box appears. From here, an FPGA bitstream (.BIT)
file is selected. Be sure to select the .BIT file by using the paths below.

Bitstream:

C:\designs\maxim\RD11V01_00\RD11_ZED_V01_00\Design_Files\top.sdk\
SDK\SDK_Export\arm_system_hw_platform\system.bit

Press Program.

It takes approximately 10 seconds to download the FPGA, then a message box
indicating FPGA configuration complete appears.

Fresno (MAXREFDES11#) ZedBoard Quick Start Guide

10. Set up 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 o r
HyperTerminal should be invoked.

The ZedBoard utilizes the Cypress USB-UART bridge IC. If the Windows OS
cannot automatically install the driver for the Cypress USB-UART bridge IC, the
driver is available for download from www.cypress.com. The driver is WHQL
certified for the default Cypress VID / PID of 0x04B4 / 0x0008.

Once installed, the Windows OS 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. 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.

11. Use the Xilinx SDK to download and run the executable ELF (.ELF) file on the
ARM Cortex-A9 processor using the following steps.

Right-click the mouse while the MAXREFDES11 C project is selected, choose
the Run As menu, and then Run Configurations… menu as shown below.

12

15

Fresno (MAXREFDES11#) ZedBoard Quick Start Guide

Verify the application is selected on the Main tab.

On the Device Initialization tab, click Browse… button to select the right
initialization TCL file and press the Run button.

16

Fresno (MAXREFDES11#) ZedBoard Quick Start Guide

Once the Debug/MAXREFDES11 configuration is set up once, you just need to
press the Run button if you ever want to run the program again.

17

Fresno (MAXREFDES11#) ZedBoard Quick Start Guide

At this point, the application will be running on the Cortex-A9 and the terminal program
should show the menu below. Make the desired selections by pressing t he appropriate
keys on the keyboard. For example, to select continuous sampling, press 0.
