CPLD interface to expose LPC43xx microcontroller SGPIO peripheral, either as all inputs or all outputs.

Requirements

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

  • Xilinx WebPACK 13.4 for Windows or Linux.

  • 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".

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.

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_passthrough.svf file to the CPLD.
