1.1 What You’ll Need

The following checklists detail items that are shipped with the XDS510PP

MPSD emulator and additional items you’ll need to use these tools.

Hardware checklist

__ host An IBM PC/AT or compatible ISA/EISA-based PC with a hard-

disk system and a 1.44M floppy-disk drive

__ memory Minimum of 640K; in addition, if you are running under Microsoft

Windows, you’ll need at least 256K of extended memory

__ display Monochrome or color (color recommended)

__ parallel port One centronics printer port, bidirectional for 4 bit, 8 bit, or EPP

compatible,

__ emulator module 5 Volts DC (125 milliamps)

power requirements

__ target system A board with an appropriate target device

__ connector to 12-pin connector (two rows of six pins) --- see Chapter 2 for

target system more information about this connector

__ optional hardware A Microsoft-compatible mouse

An EGA or VGA compatible graphics display card and a large monitor.

The debugger has several options that allow you to change the overall

size of the debugger display. If you have an EGA or VGA compatible

graphics card, you can take advantage of some of these larger screen

sizes. These larger screen sizes are most effective when used with a

large (17” or 19”) monitor. (To use a larger screen size, you must

invoke the debugger with an appropriate option. For more information

about options, refer to the invocation section in Chapter 1, Overview

of a Code Development and Debugging System, in the TMS32OC5x

C Source Debugger User’s Guide.)

1.2 Step 1: Installing the XDS510PP MPSD Emulator Pod

This section contains the hardware installation information for the emulator pod.

Preparing the emulator board for installation

The printer port connection on the back of the PC is a 25 Pin Female D connector.

Connect one end of the supplied cable to the printer port that you intend to use

(LPT1 or LPT2). Connect the other end of the cable to the 25 pin connector on the

XDS510PP emulator pod. The XDS510PP is also known as a scan path adapter.

The XDS510PP can be powered from two different sources. The easiest is to use

power from the target system. This is done automatically when the target cable is

connected. The pod uses the PD pin on the cable. The trace going to this pin on the

target board must be able to carry the current requirements of the pod. The second

source of power is the included 5 volt power supply

Warning: The power input to the pod must be regulated. Voltages higher than 5 volts

will destroy the emulator

Note: The external power supply must be used for 3 volt target systems.

Do not connect or disconnect the 25-pin D connector while the PC is powered up.

Do not connect or disconnect the 12-pin cable while the target system is powered up.

Target Cable Connectors:

Be very careful with the target cable connectors. connect them gently; don’t force

them into position, or you may damage the connectors.

1.3 Step 2: Connecting the XDS510PP to Your Target System

Figure 1-1 shows how you connect the XDS510PP emulator pod and 25 conductor

cable to your target system. In most cases, the target system will be a target board

of your own design.

Setting up the XDS510PP.INI file

The xds510pp.ini file is used to set driver parameters. The “.INI” should be located in

the same directory as the HLL Debugger. The D_DIR environment variable is used to

select the Debugger directory. If the xds510pp.ini file doesn’t exist or can’t be found

certain parameters are used as default. Shown below are the parameters and their

defaults.

speed = 25

mode = spp4

port -p command line parameter, or 240 if no command line

When the xds510pp.ini file is invoked there are four parameters which can be used.

These parameters are: speed, port, mode, and timing.

The ‘speed’ parameter selects the amount of delay between port accesses. The higher

the value the more delay added. A good value to start with is 25.

example: speed = 25

The ‘port’ parameter selects the PC’s printer port. The default value is 378. Other

values are 278 and 3BC.

example: port = 278

The mode parameter selects the type of hardware supported by the host PC. The three

modes are shown in the table below:

The “spp4” mode should work on all machines, but is the slowest. The “spp8” mode

requires a bidirectional parallel port. The “epp” mode is the fastest but requires an EPP

compatible parallel port on the host PC. If you are using EPP mode you must make

sure the PC is configured for EPP operation. Check the documentation that came with

the PC or add-in card on how to configure the parallel port. The default mode is “spp4”.

example: mode = epp

Table 1: Parallel Port Modes

Modes Description

spp4 standard parallel port

spp8 bi-directional port

epp enhanced parallel port

Spectrum Digital, Inc

1-6 XDS510PP MPSD Emulator Pod Installation Guide

The timing parameter is used to select alternate timing for the TDI and TMS signals.

The default operation is to change the state of these signals on the falling edge of the

TCK_RET signal. When alternate timing is selected TDI and TMS are changed to the

rising edge of the clock. The default mode is to use the default timing.

example: timing = alternate

As shipped from the factory the xds510pp.ini file has the parameters set as:

speed = 25

mode = epp

port = 378

Resetting the emulator

To reset the emulator, execute the emurst.exe file from the file manager or explorer.

The emulator should respond with no errors.

1.4 Utility Programs

There are several utility programs that can be found in the installation directory. One

such program is “PORTCHK”. This program searches for parallel ports and tries to

detect if they are bi-directional. To run this program type “PORTCHK” at the

command line prompt. This program does not require any arguments.

There may be other utility programs on the diskette that is shipped with the

XDS510PP. These programs may aid you in installing the XDS510PP on a

particular PC hardware configuration. Refer to the ‘readme’ files or the ‘port

utilities’ manual for their use.
