1. What You’ll Need
The following checklists detail items that are shipped with the ’C3x C source
debugger and EVM and additional items you’ll need to use these tools.
Hardware checklist
host An IBM PC/AT or 100% compatible ISA/EISA-based PC with a
hard-disk system and a 1.2-Mbyte floppy-disk drive
memory Minimum of 640K bytes; in addition, if you are running under
MS-Windows, you’ll need at least 256K bytes of extended memory.
display Monochrome or color (color recommended)
slot One 8- or 16-bit slot
EVM board
power requirements Approximately 1 ampere @ 5 volts (5 watts)
optional hardware A Microsoft-compatible mouse
AnEGA-orVGA-compatiblegraphicsdisplaycardandalargemon-
itor. 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
theselargerscreensizes.Theselargerscreensizesaremosteffec-
tive when used with a large (17” or 19”) monitor. (To use a larger
screen size, you must invoke the debugger with an appropriate op-

To minimize the risk of electric shock and fire hazard, be sure that
all major components that you interface with Texas Instruments
devices are limited in energy and certified by one or more of the
following agencies: UL, CSA, VDE, or TUV.

What You’ll Need

Software checklist
operating system MS-DOS or PC-DOS (version 3.0 or later)
Optional: MS-Windows (version 3.0 or later)
software tools TMS320floating-pointfamilyDSP(’C3x/’C4x)assemblerandlinker
Optional: TMS320C3x/C4x C compiler
required files † evmrst.exe resets the EVM
optional files † init.cmd is a file that contains debugger commands. The version of
this file that’s shipped with the debugger defines a ’C3x memory
map. If this file isn’t present when you invoke the debugger, then all
memory is invalid at first. When you first start using the EVM, this
memory map should be sufficient for your needs. Later, you may
wanttodefineyourownmemory map.Forinformation aboutsetting
up your own memory map, refer to Chapter 5,
Defining a Memory
Map,
in the TMS320C3x C Source Debugger User’s Guide.
†
init.clr is a general-purpose screen configuration file. If this file isn’t
present when you invoke the debugger, the debugger uses the de-
fault screen configuration.
†The default configuration is for color monitors; an additional file,
mono.clr , can be used for monochrome monitors. When you first
starttousethedebugger,thedefaultscreenconfigurationshouldbe
sufficient for your needs. Later, you may want to define your own
custom configuration.
For information about these files and about setting up your own
screenconfiguration,refer toChapter9,

2. Step 1: Installing the EVM Board in Your PC
This section contains the hardware installation information for the EVM.
Preparing the EVM board for installation
Before you install the EVM board, you must be sure that the board’sswitches
aresettocorrectlyidentifytheI/Ospacethattheboardcanuse.The’C3xEVM
board has four switches:
- Switches 1 and 2 identify your system’s I/O address space. You can
change these switch settings to identify the I/O address space that the
EVM uses in your system.
- Switches 3 and 4 are for manufacturing test.
Leave these switches in the
default positions.

switch numbers.

’C3x EVM
default switch settings
Switches are shipped in the default settings shown here and described in
Table 1.IfyouuseanI/Ospacethatdiffersfromthedefault,changetheswitch
settings for switches 1 and 2. Table 1 shows you how to do this.
In most cases, you can leave the switch settings in the default position.
However, you must ensure that the ’C3x EVM I/O address space does not
conflict with other bus settings. For example, if you’ve installed a bus mouse
in your system, you may not be able to use the default switch settings for the
I/O address space—the mouse might use this space. Refer to your PC
technical reference manual and your other hardware-board manuals to see if
there are any I/O space conflicts. If you find a conflict, use one of the settings
in Table 1
.

Setting the EVM board into your PC
To minimize risk of personal injury, always turn off the power to all
computer-system components and unplug power cords.
After you’ve prepared the EVM board for installation, follow these steps.
Step 1: Turn off your PC’s power and unplug the power cord.
Step 2: Remove the cover of your PC.
Step 3: Remove the mounting bracket from an unused 8-bit or 16-bit slot.
Step 4: Install the EVM board in an 8-bit or 16-bit slot (see Figure 2).
Step 5: Tighten down the mounting bracket.
Step 6: Replace the PC cover.
Step 7: Plug in the power cord and turn on the PC’s power.
