Regulatory Compliance

The ADSP-BF527 EZ-KIT Lite is designed to be used solely in a labora­tory environment. The board is not intended for use as a consumer end
product or as a portion of a consumer end product. The board is an open
system design which does not include a shielded enclosure and therefore
may cause interference to other electrical devices in close proximity. This
board should not be used in or near any medical equipment or RF devices.

The ADSP-BF527 EZ-KIT Lite is currently being processed for certifica­tion that it complies with the essential requirements of the European
EMC directive 89/336/EEC amended by 93/68/EEC and therefore carries
the “CE” mark.

The EZ-KIT Lite evaluation system contains ESD (electrostatic discharge)
sensitive devices. Electrostatic charges readily accumulate on the human
body and equipment and can discharge without detection. Permanent
damage may occur on devices subjected to high-energy discharges. Proper
ESD precautions are recommended to avoid performance degradation or
loss of functionality. Store unused EZ-KIT Lite boards in the protective
shipping package.

PREFACE

Thank you for purchasing the ADSP-BF527 EZ-KIT Lite®, Analog
Devices, Inc. evaluation system for Blackfin® processors.

Blackfin processor family embodies a new type of embedded processor
designed specifically to meet the computational demands and power con­straints of today’s embedded audio, video, and communications
applications. They deliver breakthrough signal-processing performance
and power efficiency within a reduced instruction set computing (RISC)
programming model.

Blackfin processors support a media instruction set computing (MISC)
architecture. This architecture is the natural merging of RISC, media
functions, and digital signal processing (DSP) characteristics. Blackfin
processors deliver signal-processing performance in a microprocessor-like
environment.

Based on the Micro Signal Architecture (MSA), Blackfin processors com­bine a 32-bit RISC instruction set, dual 16-bit multiply accumulate
(MAC) DSP functionality, and eight-bit video processing performance
that had previously been the exclusive domain of very-long instruction
word (VLIW) media processors.

ADSP-BF527 EZ-KIT Lite Evaluation System Manual xi

The evaluation board is designed to be used in conjunction with the Visu­alDSP++
ADSP-BF527 Blackfin processors. The VisualDSP++ development envi­ronment aids advanced application code development and debug, such as:

Access to the ADSP-BF527 processor from a personal computer (PC) is
achieved through a USB port or an optional JTAG emulator. The USB
interface gives unrestricted access to the ADSP-BF527 processor and the
evaluation board peripherals. Analog Devices JTAG emulators offer faster
communication between the host PC and target hardware. Analog Devices
carries a wide range of in-circuit emulation products. To learn more about
Analog Devices emulators and processor development tools, go to

• Create, compile, assemble, and link application programs written
in C++, C, and ADSP-BF527 assembly

• Load, run, step, halt, and set breakpoints in application programs

• Read and write data and program memory

• Read and write core and peripheral registers

• Plot memory

The ADSP-BF527 EZ-KIT Lite provides example programs to demon­strate the capabilities of the evaluation board.

and equipment and can discharge without detection. Permanent damage may
occur on devices subjected to high-energy discharges. Proper ESD precautions
are recommended to avoid performance degradation or loss of functionality.
Store unused EZ-KIT Lite boards in the protective shipping package.

When removing the EZ-KIT Lite board from the package, handle the
board carefully to avoid the discharge of static electricity, which can dam­age some components. Figure 1-1 shows the default jumper settings,
switches, connector locations, and LEDs used in installation. Confirm
that your board is in the default configuration before using the board.

Using ADSP-BF527 EZ-KIT Lite

Installation and Session Startup

For correct operation, install the software and hardware in the order pre­sented in the VisualDSP++ Installation Quick Reference Card.

There are two USB interfaces on the ADSP-BF527 EZ-KIT Lite.
Be sure to use the debugger’s interface (ZJ1) when connecting your
computer to the board with provided USB cable. The other USB
interface (labelled USB-OTG, P1) is for applications use.

1. Verify that the yellow USB monitor LED (ZLED3, located near the
USB connector) is lit. This signifies that the board is communicat­ing properly with the host PC and is ready to run VisualDSP++.

2. If you are running VisualDSP++ for the first time, navigate to the
VisualDSP++ environment via the Start–>Programs menu. The
main window appears. Note that VisualDSP++ does not connect to
any session. Skip the rest of this step to step 3.

If you have run VisualDSP++ previously, the last opened session
appears on the screen. You can override the default behavior and
force VisualDSP++ to start a new session by pressing and holding
down the Ctrl key while starting VisualDSP++. Do not release the
Ctrl key until the Session Wizard appears on the screen. Go to
step 4.

3. To connect to a new EZ-KIT Lite session, start Session Wizard by
selecting one of the following.

• From the Session menu, New Session.

• From the Session menu, Session List. Then click New Ses-
sion from the Session List dialog box.

• From the Session menu, Connect to Target.

Installation and Session Startup

4. The Select Processor page of the wizard appears on the screen.
Ensure Blackfin is selected in Processor family. In Choose a target
processor, select ADSP-BF527. Click Next.

5. The Select Connection Type page of the wizard appears on the
screen. Select EZ-KIT Lite and click Next.

6. The Select Platform page of the wizard appears on the screen.
Ensure that the selected platform is ADSP-BF527 EZ-KIT Lite via
Debug Agent. Specify your own Session name for the session or
accept the default name.

The session name can be a string of any length; although, the box
displays approximately 32 characters. The session name can
include space characters. If you do not specify a session name,
VisualDSP++ creates a session name by combining the name of the
selected platform with the selected processor. The only way to
change a session name later is to delete the session and to open a
new session.

Click Next.

7. The Finish page of the wizard appears on the screen. The page dis-
plays your selections. Check the selections. If you are not satisfied,
click Back to make changes; otherwise, click Finish. VisualDSP++
creates the new session and connects to the EZ-KIT Lite. Once
connected, the main window’s title is changed to include the ses­sion name set in step 6.
