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 One +7V power supply One -6V power supply Fremont (MAXREFDES6#) 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 Fremont design running by downloading and running the FPGA project.
Fremont (MAXREFDES6#) Nexys 3 Quick Start Guide Figure 1. Fremont Board Connected to Nexys 3 Development Kit Figure 2.
Fremont (MAXREFDES6#) 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.
Fremont (MAXREFDES6#) Nexys 3 Quick Start Guide 4. Procedure 1. Connect the Fremont board to the JB1 port of a Nexys 3 development kit as shown in Figure 1. Power up the Nexys 3 development kit. 2. Connect the +7V power supply to the EXT_V+ connector. Connect the -6V power supply to the EXT_V- connector. Connect the ground terminal of the power supplies to the GND2 connector. 3. Download the latest RD6V01_00.ZIP file located at www.maximintegrated.com/fremont.
Fremont (MAXREFDES6#) Nexys 3 Quick Start Guide 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\RD6V01_00\RD6_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.
Fremont (MAXREFDES6#) Nexys 3 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.
Fremont (MAXREFDES6#) Nexys 3 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\RD6V01_00\RD6_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.
Fremont (MAXREFDES6#) Nexys 3 Quick Start Guide 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 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\RD6V01_00\RD6_NEXYS3_V01_00\Design_Files\ sdkWorkspace\system_hw_platform\system.
Fremont (MAXREFDES6#) 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 and a message box indicating FPGA configuration complete appears.
Fremont (MAXREFDES6#) Nexys 3 Quick Start Guide 10. 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.
Fremont (MAXREFDES6#) Nexys 3 Quick Start Guide 11. Use the Xilinx SDK to download and run the executable ELF (.ELF) file on the MicroBlaze using the following steps. Right Click the mouse while the MAXREFDES6 C project is selected, choose the Run As menu, and then Run Configurations… menu as shown below.
Fremont (MAXREFDES6#) Nexys 3 Quick Start Guide Next, double-click the mouse on the Xilinx C/C++ ELF menu.
Fremont (MAXREFDES6#) Nexys 3 Quick Start Guide Next, press the Search Project button.
Fremont (MAXREFDES6#) Nexys 3 Quick Start Guide Double-click on the MAXREFDES6.elf binary.
Fremont (MAXREFDES6#) Nexys 3 Quick Start Guide Verify the application is selected and press the Run button. Once the Debug/MAXREFDES6 configuration is setup once, you just need to press the Run button if you ever want to run the program again.
Fremont (MAXREFDES6#) Nexys 3 Quick Start Guide At this point, the application will be 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.
