Required Equipment • • • • • PC with Windows® OS with Xilinx® ISE®/SDK version 13.4 or later and two USB ports License for Xilinx EDK/SDK version 13.4 or later Campbell (MAXREFDES4#) board Nexys™3 development kit Industrial sensor or signal source 2. Overview Below is a high-level overview of the steps required to quickly get the Campbell design running by downloading and running the FPGA project.

Campbell (MAXREFDES4#) Nexys 3 Quick Start Guide 3. Included Files The top level of the hardware design is a Xilinx ISE Project Navigator Project (.XISE) for Xilinx ISE version 13.4. The Verilog-based HDL design instantiates the MicroBlaze core, the support hardware required to run the MicroBlaze, and the peripherals that interface to the Pmod ports.
Campbell (MAXREFDES4#) Nexys 3 Quick Start Guide 4. Procedure Note: In the following sections, software-related items are identified by bolding. Text in bold refers to items directly from the EV kit software. Text in bold and underlined refers to items from the Windows operating system. 1. Connect the Campbell board to the JB1 port of a Nexys 3 development kit as shown on the first page of this document. Power up the Nexys 3 development kit.
Campbell (MAXREFDES4#) Nexys 3 Quick Start Guide 4. Open the Xilinx Software Development Kit (SDK) from the Windows Start menu. 5. 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\RD4V01_00\RD4_NEXYS3_V01_00\Design_Files\sdkWorkspace 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.
Campbell (MAXREFDES4#) Nexys 3 Quick Start Guide 6. 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.
Campbell (MAXREFDES4#) Nexys 3 Quick Start Guide 7. 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\RD4V01_00\RD4_NEXYS3_V01_00\Design_Files\sdkWorkspace and the missing projects should appear in SDK Project Explorer with their checkboxes checked. Click Finish to import the projects.
Campbell (MAXREFDES4#) Nexys 3 Quick Start Guide 8. 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 as well as an FPGA BMM (.BMM) file. Be sure to select the .BIT file and the .BMM by using the paths below. Bitstream: C:\designs\maxim\RD4V01_00\RD4_NEXYS3_V01_00\Design_Files\ sdkWorkspace\system_hw_platform\system.
Campbell (MAXREFDES4#) Nexys 3 Quick Start Guide Additionally, make sure bootloop is selected as shown, then press Program. It takes approximately 10 seconds to download the FPGA then a message box indicating “FPGA configuration complete” appears. 9. 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.
Campbell (MAXREFDES4#) Nexys 3 Quick Start Guide 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. 10. Use the Xilinx SDK to download and run the executable ELF (.
Campbell (MAXREFDES4#) Nexys 3 Quick Start Guide Next, double-click the mouse on the Xilinx C/C++ ELF menu.
Campbell (MAXREFDES4#) Nexys 3 Quick Start Guide Next, press the Search Project button.
Campbell (MAXREFDES4#) Nexys 3 Quick Start Guide Double-click on the MAXREFDES4.elf binary.
Campbell (MAXREFDES4#) Nexys 3 Quick Start Guide Verify the application is selected and press the Run button. Once the Debug/MAXREFDES4 configuration is set up once, you just need to press the Run button if you ever want to run the program again.
Campbell (MAXREFDES4#) Nexys 3 Quick Start Guide At this point, the application is running on the MicroBlaze and the terminal program should show the menu below. Make the desired selections by pressing the appropriate keys on the keyboard. For example, to select continuous sampling, press 0.
