Sonoma (MAXREFDES14#) LX9 MicroBoard 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 120V AC power source or wall outlet AC load Sonoma (MAXREFDES14#) board Avnet Spartan®-6 LX9 MicroBoard 2. Overview Below is a high-level overview of the steps required to quickly get the Sonoma design running by downloading and running the FPGA project.
Sonoma (MAXREFDES14#) LX9 MicroBoard Quick Start Guide Figure 1. Sonoma Board Connected to LX9 Kit Figure 2.
Sonoma (MAXREFDES14#) 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 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.
Sonoma (MAXREFDES14#) LX9 MicroBoard Quick Start Guide 4. Procedure 1. Connect the Sonoma board to the JB1 port of a LX9 MicroBoard as shown in Figure 1. 2. Connect the P1 USB connector of the LX9 MicroBoard directly to the computer. Or, use a USB extension cable to connect the LX9 MicroBoard to the computer. 3. Connect the AC power supply and the load to the Sonoma board as shown in Figure 4. 4. Download the latest RD14V01_00.ZIP file located at www.maximintegrated.com/sonoma.
Sonoma (MAXREFDES14#) LX9 MicroBoard Quick Start Guide 6. Open the Xilinx Software Development Kit (SDK) from the Windows Start menu. 7. 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\RD14V01_00\RD14_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.
Sonoma (MAXREFDES14#) LX9 MicroBoard Quick Start Guide 8. 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.
Sonoma (MAXREFDES14#) LX9 MicroBoard Quick Start Guide 9. 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\RD14V01_00\RD14_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.
Sonoma (MAXREFDES14#) LX9 MicroBoard Quick Start Guide 10. 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\RD14V01_00\RD14_LX9_V01_00\Design_Files\ sdkWorkspace\system_hw_platform\system.
Sonoma (MAXREFDES14#) LX9 MicroBoard Quick Start Guide 11. 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.
Sonoma (MAXREFDES14#) LX9 MicroBoard Quick Start Guide 12. 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 MAXREFDES14 C project is selected, choose the Run As menu, and then Run Configurations… menu as shown below.
Sonoma (MAXREFDES14#) LX9 MicroBoard Quick Start Guide Next, double-click the mouse on the Xilinx C/C++ ELF menu.
Sonoma (MAXREFDES14#) LX9 MicroBoard Quick Start Guide Next, press the Search Project button.
Sonoma (MAXREFDES14#) LX9 MicroBoard Quick Start Guide Double-click on the MAXREFDES14.elf binary.
Sonoma (MAXREFDES14#) LX9 MicroBoard Quick Start Guide Verify the application is selected on the Main tab and press the Run button. Once the Debug/MAXREFDES14 configuration is setup once, you just need to press the Run button if you ever want to run the program again.
Sonoma (MAXREFDES14#) LX9 MicroBoard 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 Register Read command, press 0.
