Santa Fe (MAXREFDES5#) Nexys 3 Quick Start Guide 1. 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 Santa Fe (MAXREFDES5#) 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 Santa Fe design running by downloading and running the FPGA project.
Santa Fe (MAXREFDES5#) Nexys 3 Quick Start Guide Figure 1. Santa Fe Board Connected to Nexys 3 Development Kit Figure 2.
Santa Fe (MAXREFDES5#) 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.
Santa Fe (MAXREFDES5#) Nexys 3 Quick Start Guide 4. Procedure 1. Connect the Santa Fe board to the JB1 port of a Nexys 3 development kit as shown in Figure 1. Power up the Nexys 3 development kit. The Santa Fe board is completely powered from the Nexys 3 development kit and no external power is required. 2. Download the latest RD5V01_00.ZIP file at www.maximintegrated.com/AN5561. All files available for download are available at the bottom of the page. 3. Extract the RD5V01_00.
Santa Fe (MAXREFDES5#) 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\RD5V01_00\RD5_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.
Santa Fe (MAXREFDES5#) 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.
Santa Fe (MAXREFDES5#) 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\RD5V01_00\RD5_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.
Santa Fe (MAXREFDES5#) 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\RD5V01_00\RD5_NEXYS3_V01_00\Design_Files\ sdkWorkspace\system_hw_platform\system.
Santa Fe (MAXREFDES5#) 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.
Santa Fe (MAXREFDES5#) Nexys 3 Quick Start Guide 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 (.ELF) file on the MicroBlaze using the following steps.
Santa Fe (MAXREFDES5#) Nexys 3 Quick Start Guide Next, double-click the mouse on the Xilinx C/C++ ELF menu.
Santa Fe (MAXREFDES5#) Nexys 3 Quick Start Guide Next, press the Search Project button.
Santa Fe (MAXREFDES5#) Nexys 3 Quick Start Guide Double-click on the MAXREFDES5.elf binary.
Santa Fe (MAXREFDES5#) Nexys 3 Quick Start Guide Verify the application is selected and press the Run button. Once the Debug/MAXREFDES5 configuration is set up once, you just need to press the Run button if you ever want to run the program again.
Santa Fe (MAXREFDES5#) 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 channel AIN0, press 0.
