Alameda (MAXREFDES24#) LX9 MicroBoard 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) Alameda (MAXREFDES24#) board Avnet Spartan®-6 LX9 MicroBoard One +24V 1A DC power supply One 750Ω 0.25W resistor 2.
Alameda (MAXREFDES24#) LX9 MicroBoard Quick Start Guide Figure 1. Alameda Board Connected to LX9 Kit Figure 2.
Alameda (MAXREFDES24#) LX9 MicroBoard 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 14.2. 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.
Alameda (MAXREFDES24#) LX9 MicroBoard Quick Start Guide 4. Procedure 1. Connect the Alameda board to the J4 and J5 ports of an LX9 MicroBoard as shown in Figure 1. 2. Connect the +24V power supply positive terminal and the ground terminal to the +24V and the PGND connectors on the Alameda board, respectively. 3. Connect one end of the 750Ω load resistor to the OUT1 connector on the Alameda board. Connect the other end of the 750Ω load resistor to the AGND1 connector on the Alameda board. 4.
Alameda (MAXREFDES24#) LX9 MicroBoard Quick Start Guide 10. Open the Xilinx Software Development Kit (SDK) from the Windows Start menu. 11. 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\RD24V01_00\RD24_LX9_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.
Alameda (MAXREFDES24#) LX9 MicroBoard Quick Start Guide 12. 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.
Alameda (MAXREFDES24#) LX9 MicroBoard Quick Start Guide 13. 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\RD24V01_00\RD24_LX9_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.
Alameda (MAXREFDES24#) LX9 MicroBoard Quick Start Guide 14. 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 file by using the paths below. Bitstream: C:\designs\maxim\RD24V01_00\RD24_LX9_V01_00\Design_Files\top.
Alameda (MAXREFDES24#) LX9 MicroBoard Quick Start Guide 15. 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.
Alameda (MAXREFDES24#) LX9 MicroBoard Quick Start Guide 16. 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 MAXREFDES24 C project is selected, choose the Run As menu, and then Run Configurations… menu as shown below.
Alameda (MAXREFDES24#) LX9 MicroBoard Quick Start Guide Next, double-click the mouse on the Xilinx C/C++ ELF menu.
Alameda (MAXREFDES24#) LX9 MicroBoard Quick Start Guide Next, press the Search Project button.
Alameda (MAXREFDES24#) LX9 MicroBoard Quick Start Guide Double-click on the MAXREFDES24.elf binary.
Alameda (MAXREFDES24#) LX9 MicroBoard Quick Start Guide Verify the application is selected on the Main tab and press the Run button. Once the Debug/MAXREFDES24 configuration is set up once, you just need to press the Run button if you ever want to run the program again.
Alameda (MAXREFDES24#) LX9 MicroBoard 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 current output, press 0.
