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](http://dangerousprototypes.com/docs/Bus_Blaster_v2_buffer_logic).
|
|
* 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.
