About the Software and Firmware PCD8 8-bit DMA Interface User’s Guide

3 EDT, Inc. May 2007

Compatible single-channel Xilinx configuration files must be loaded in the PCI Xilinx on the main

boards. These are:

cda1.bit PCI Xilinx configuration file for the PCI CDa.

pcd20.bit PCI Xilinx configuration file for PCI CD-20 boards.

pcd60.bit PCI Xilinx configuration file for PCI CD-60 boards.

pciss1.bit Single-channel PCI Xilinx configuration file for PCI SS boards.

pcigs1.bit Single-channel PCI Xilinx configuration file for PCI GS boards.

The following software initialization files are available for use with the

initpcd automatic configuration

utility:

pcda8.cfg Software initialization file for the PCI SS/GS and the PCI CDa.

pcd8_src.cfg Software initialization file for the PCI CD.

The firmware file names you see in the EDT distribution do not match the file names given above

because PCI Bus slots come in two varieties: those supplying 3 V power, and those supplying 5 V

power. Different firmware is required for the two kinds of slots, but the correct firmware file is chosen

automatically when you run

pciload or any other EDT-supplied firmware loading utility.

For example, you may see files named

cda16_3v.bit and cda16_5v.bit, but the correct argument

to supply to load the firmware is

cda16.bit.

In some cases, you may also see additional firmware files incorporating changes required for various

board revisions, or files with the same name in different subdirectories. You need not be concerned

with any of these variations of name or path, however. In all cases, the names given above are the

correct arguments to supply to the firmware-loading utilities.

The PCD Device Driver

The PCD device driver is the software running on the host that allows the host operating system to

communicate with the PCD8. The driver is loaded into the kernel upon installation, and thereafter runs

as a kernel module. The driver name and subdirectory is specific to each supported operating system;

the installation script handles those details for you, automatically installing the correct device driver in

the correct operating system-specific manner.

FPGA Configuration Files

FPGA configuration files define the firmware required for the PCI FPGA and the UI FPGA. The PCI

FPGA firmware files are in the

flash subdirectory of the EDT top-level distribution directory. UI FPGA

firmware files are in the

bitfiles subdirectory of the EDT top-level distribution directory.

Each FPGA must be loaded with the firmware specific to the chosen interface, and the firmware in one

FPGA must be compatible with the firmware in the other. By default, the correct FPGA configuration

file for the PCI FPGA is loaded at the factory. However, you’ll need to load the required FPGA

configuration file for the UI FPGA yourself.

The firmware files specific to your PCD8 are listed at the beginning of this section. Instructions for

loading them are provided in Configuring the PCD8.
