GENERAL DESCRIPTION

The DSTINIm400 is a fully assembled and tested
circuit board that evaluates the DS80C400 network
microcontroller. In addition to the DS80C400, the
DSTINIm400 includes a real-time clock, 1MB flash,
1MB static RAM, and support for an external
Ethernet PHY for connecting to a wide variety of
networks. The circuit board is designed as a module
to be plugged into a 144-pin SODIMM connector. For
evaluation, the DSTINIm400 can be inserted into the
DSTINIs400 socket board. The combination of the
two boards allows full evaluation of the features of
the DS80C400 using an Ethernet network.

QUICK START

Recommended Equipment

The minimum hardware and software requirements are:
· TINI Hardware Requirements

TINIm400 Verification Module or equivalent
TINIs400 Sockets Board or equivalent

· TINI Software Requirements

TINI Software Development Kit

Version 1.1 or later

JDK (JavaTM Development Kit)

from Sun Microsystems or equivalent

Java Communications API

from Sun Microsystems or

www.rxtx.org

· Development System Requirements

Operating system meeting requirements of the JDK from Sun Microsystems
1 RS-232 (COM) port--115200 baud recommended

RS-232C serial cable DB9 male to DB9 female

: Radio Shack Catalog Number 26-117 or equivalent

Crossover Ethernet cable

: For direct connection to a host computer, use a crossover Ethernet cable such as

the Radio Shack Catalog Number 950-0368 or equivalent. To connect to a router or hub, use a straight-
through Ethernet cable.

5V DC power supply

capable of supplying 150mA: Radio Shack Catalog Number 900-2740 or equivalent

(center positive)

Procedure

1) Prior to beginning, verify power is not connected to the TINIs400 sockets board.
2) Insert the TINIm400 Verification Module into the 144-pin connector on the TINIs400 sockets board.
3) Verify the jumper labeled as DTR Reset (J14) is placed on the sockets board.
4) Attach an RS-232 serial cable to the connector labeled "LoaderSerial 0" on the TINIm400 sockets board as

shown in

Figure 1

5) Connect the serial cable to a serial port on your PC.
6) Next, attach the crossover Ethernet cable between the PC and the TINIs400 sockets board.
7) Note: If the TINI sockets board is not being connected directly to a network interface card, but instead to a

separate network port on a hub or switch, a straight through Ethernet patch cable should be used.

8) Connect the power adapter to your TINIs400 sockets board as shown in

Figure 1

. A center positive 5V DC

regulated power supply must be used with the TINIs400 sockets board. Other sockets boards may have
different power requirements. Refer to the sockets board documentation for more information.

9) Plug the power adapter into a wall socket.

The TINI Software Development Kit has been extensively tested with JDK1.3 from Sun Microsystems. Later versions of the JDK should work in

the same manner. Check the documentation for your version of the JDK to verify the installation procedure.

SOFTWARE SETUP

First, download and install the Java Development Kit and Java Communications API from Sun Microsystems.
Installation instructions and example applications are included in both packages. You should verify correct
installation by running the

BlackBox

example provided with the Java Communications API.

Loading the TINI Runtime Environment

Download the TINI Software Development Kit from

www.maxim-ic.com/TINI

. The download file should be unzipped

to a location of your choice on your hard drive (<TINI SDK Install Dir>).

To begin using the TINIm400 Verification Module, the TINI runtime environment must first be loaded into the flash
of the verification module. Loading the runtime environment requires executing a program called JavaKit.
Application binaries are loaded through the serial port of the TINI verification module.

Running JavaKit

To run JavaKit, open a command shell or DOS prompt on your PC. Change to the <TINI SDK Install Dir>\bin
directory.

Next, type java classpath tini.jar JavaKit 400 flash 40 at the command prompt and press
Enter to run the JavaKit application. If you have the Java Development Kit and the Java Communications API
properly installed, JavaKit should appear on the screen.

Select the port name where the TINI Verification Module is attached. Press the Open Port button. The default
baud rate of 115200 should be used on all platforms where it is supported.

After opening the port, press the Reset button. The loader prompt should be displayed on the JavaKit screen
(

Figure 2

If the message is not displayed, verify the cable connections and check that the correct port name is selected.
If everything appears to be attached correctly, read the Running_JavaKit.txt file contained in the TINI SDK for
more detailed information.

At the JavaKit prompt, type B0 and press Enter, followed by F0 and Enter. This clears the RAM of the TINI
Verification Module. Any time a new runtime environment is loaded the memory should be cleared.

Now click on the File menu in JavaKit and select

Load File

A file dialog appears on the screen. Browse to

the <TINI SDK Install Dir>\bin directory and select the

tini_400.tbin

file and click the Open button. Load

Complete is displayed on the screen when the firmware is loaded, this can take up to 30 seconds.

To load the command shell, click on the File

menu and select

Load File

again. Select the

slush_400.tbin

file and click on the Open button. When Load Complete appears, slush has been

successfully loaded into the flash of the TINIm400 Verification Module.

Press the reset button and the JavaKit loader prompt shown in

Figure 2

is displayed.

10)

At the JavaKit prompt, type E and hit Enter. Slush begins booting and text similar to that shown in

Figure 3

prints on the JavaKit screen.

11)

Press Enter and a slush login prompt is displayed. Type in the username root and press

Enter. The initial

password is

tini

12)

You should now be logged into slush. To view a list of valid shell commands, type help at the command
prompt. Detailed information on specific commands, such as dir, can be obtained by typing help,

followed by

the command.
