CPLD interface between LPC43xx microcontroller SGPIO peripheral and MAX5864 RF codec.

Requirements

To build this VHDL project and produce an SVF file for flashing the CPLD:

  • Xilinx WebPACK 13.4 for Windows or Linux.

To program the SVF file into the CPLD:

  • Dangerous Prototypes Bus Blaster v2:

    • Configured with JTAGKey buffers.
    • Connected to CPLD JTAG signals on Jellybean.
  • urJTAG built with libftdi support.

  • BSDL model files for Xilinx CoolRunner-II XC264A, available at xilinx.com, in the "Device Models" Support Resources section of the CoolRunner-II Product Support & Documentation page. Only one file from the BSDL package is required, and the "program" script below expects it to be at the relative path "bsdl/xc2c/xc2c64.bsd".

Generate an XSVF

After generating a programming file:

  • In the ISE Project Navigator, "Processes: top - Behavioral" pane, double-click "Configure Target Device".
  • Click "OK" to open iMPACT.
  • Ctrl-N to create a "New Project".
  • "Yes" to automatically create and save a project file.
  • Select "Prepare a Boundary-Scan File", choose "XSVF".
  • Select file name "default.xsvf".
  • Click "OK" to start adding devices.
  • Assign new configuration file: "top.jed".
  • Right-click the "xc2c64a top.jed" icon and select "Erase". Accept defaults.
  • Right-click the "xc2c64a top.jed" icon and select "Program".
  • Right-click the "xc2c64a top.jed" icon and select "Verify".
  • Choose menu "Output" -> "XSVF File" -> "Stop Writing to XSVF File".
  • Close iMPACT.

To Program

./program

...which connects to the Bus Blaster interface 0, sets the BSDL directory, detects devices on the JTAG chain, and writes the sgpio_if.svf file to the CPLD.
