Regulatory Compliance

The ADSP-BF526 EZ-Board 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-BF526 EZ-Board has been certified to comply with the essen­tial requirements of the European EMC directive 2004/108/EC and
therefore carries the “CE” mark.

The ADSP-BF526 EZ-Board has been appended to Analog Devices, Inc.
EMC Technical File (EMC TF) referenced DSPTOOLS1, issue 2 dated
June 4, 2008 and was declared CE compliant by an appointed Notified
Body (No.0673) as listed below.

Notified Body Statement of Compliance: Z600ANA2.031 dated
November 7, 2008.

Issued by: Technology International (Europe) Limited

Shrivenham, Swindon, SN6 8TY, UK

The EZ-Board 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-Boards in the protective shipping
package.

PREFACE

Thank you for purchasing the ADSP-BF526 EZ-Board™, Analog
Devices, Inc. evaluation system for Blackfin® processors.

Blackfin processors embody 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-BF526 EZ-Board Evaluation System Manual xi

The evaluation board is designed to be used in conjunction with the Visu­alDSP++
ADSP-BF526 Blackfin processors. The VisualDSP++ development envi­ronment aids advanced application code development and debug, such as:

Access to the ADSP-BF526 processor from a personal computer (PC) is
achieved through a USB port or an external JTAG emulator. The USB
interface of the standalone debug agent gives unrestricted access to the
processor and evaluation board’s peripherals. Analog Devices JTAG emu­lators offer faster communication between the host PC and target
hardware. To learn more about Analog Devices emulators and processor
development tools, go to http://www.analog.com/dsp/tools/.

Default Configuration

Default Configuration

The ADSP-BF526 EZ-Board board is designed to run outside your per­sonal computer as a stand-alone unit. You do not have to open your
computer case.

The EZ-Board 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-Boards in the protective shipping package.

When removing the EZ-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 and switch settings,
connector locations, and LEDs used in installation. Confirm that your
board is in the default configuration before using the board.

EZ-Board Installation

For correct operation, install the software in the order presented in the
VisualDSP++ Installation Quick Reference Card. Substitute instructions in
step 3 with instructions in this section.

There are two options to connect the EZ-Board hardware to a personal
computer (PC) running VisualDSP++ 5.0: via an Analog Devices emula­tor or via a standalone debug agent module. The standalone debug agent
allows a debug agent to interface to the ADSP-BF526 EZ-Board. The
standalone debug agent is shipped with the kit.

EZ-Board Installation

To connect the EZ-Board to a PC via an emulator:

1. Set up the EZ-Board for either battery power or wall/USB power;
see “Power Setup” on page 1-29.

2. Attach the emulator header to connector
back side of the EZ-Board.

3. Depending on the power source for the EZ-Board, do one of the
following.

• Turn ON switch SW22 (battery)

EZ-Board Session Startup

1. 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++ is not connected to
any session. Skip the rest of this step to step 2.

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 3.

2. 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.

3. 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-BF526. Click Next.

EZ-Board Session Startup

4. The Select Connection Type page of the wizard appears on the
screen. For standalone debug agent connections, select EZ-KIT
Lite and click Next. For emulator connections select Emulator,
and click Next

5. The Select Platform page of the wizard appears on the screen.
For standalone debug agent connections, ensure that the selected
platform is ADSP-BF526 EZ-KIT Lite via Debug Agent. For
emulator connections, choose the type of emulator that is con­nected. 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 open a new
session.

Click Next.

6. 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-Board. Once con­nected, the main window’s title is changed to include the session
name set in step 5.
