Carmel (MAXREFDES18#) 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.
Carmel (MAXREFDES18#) LX9 MicroBoard Quick Start Guide 4. Procedure 1. Connect the Carmel board to the J5 port of an LX9 MicroBoard as shown in Figure 1. 2. Connect the ±24V power supply positive terminal, negative terminal, and the ground terminal to the AVDD, AVSS, and AGND connectors, respectively, on the Carmel board. 3. Connect one end of the 750Ω load resistor to the OUT and SENSEVP connectors on the Carmel board. 4.
Carmel (MAXREFDES18#) LX9 MicroBoard Quick Start Guide 11. Open the Xilinx Software Development Kit (SDK) from the Windows Start menu. 12. 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\RD18V01_00\RD18_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.
Carmel (MAXREFDES18#) LX9 MicroBoard Quick Start Guide 13. 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.
Carmel (MAXREFDES18#) LX9 MicroBoard Quick Start Guide 14. 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\RD18V01_00\RD18_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.
Carmel (MAXREFDES18#) LX9 MicroBoard Quick Start Guide 15. 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\RD18V01_00\RD18_LX9_V01_00\Design_Files\top.
Carmel (MAXREFDES18#) LX9 MicroBoard Quick Start Guide 16. 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.
Carmel (MAXREFDES18#) LX9 MicroBoard Quick Start Guide 17. 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 MAXREFDES18 C project is selected, choose the Run As menu, and then Run Configurations… menu as shown below.
Carmel (MAXREFDES18#) LX9 MicroBoard Quick Start Guide Next, double-click the mouse on the Xilinx C/C++ ELF menu.
Carmel (MAXREFDES18#) LX9 MicroBoard Quick Start Guide Next, press the Search Project button.
Carmel (MAXREFDES18#) LX9 MicroBoard Quick Start Guide Double-click on the MAXREFDES18.elf binary.
Carmel (MAXREFDES18#) LX9 MicroBoard Quick Start Guide Verify the application is selected on the Main tab and press the Run button. Once the Debug/MAXREFDES18 configuration is set up once, you just need to press the Run button if you ever want to run the program again.
Carmel (MAXREFDES18#) 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.
