Regulatory Compliance

The ADSP-BF538F 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-BF538F EZ-KIT Lite has been certified to comply with the essential requirements of the European EMC directive 89/336/EEC amended by 93/68/EEC and therefore carries the “CE” mark.

The ADSP-BF538F EZ-KIT Lite has been appended to Analog Devices, Inc. Technical Construction File (TCF) referenced ‘DSPTOOLS1’ dated December 21, 1997 and was awarded CE Certification by an appointed European Competent Body as listed below.

Technical Certificate No: Z600ANA1.028

PREFACE

Thank you for purchasing the ADSP-BF538F EZ-KIT Lite®, 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 8-bit video processing performance that had previously been the exclusive domain of very-long instruction word (VLIW) media processors.

ADSP-BF538F EZ-KIT Lite Evaluation System Manual ix

The evaluation board is designed to be used in conjunction with the VisualDSP++ ADSP-BF538F Blackfin processors. The VisualDSP++ development environment gives you the ability to perform advanced application code development and debug, such as:

Access to the ADSP-BF538F 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-BF538F 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-BF538F 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-BF538F EZ-KIT Lite provides example programs to demonstrate the capabilities of the evaluation board.

The EZ-KIT Lite board has flash memory with a total of 4 MB. Flash memory can be used to store user-specific boot code, allowing the board to run as a stand-alone unit. For more information, see “Flash Memory”

on page 1-10. The board also has 64 MB of SDRAM, which can be used

by the user at runtime.

SPORT0 interfaces with the audio circuit, facilitating development of audio

signal processing applications. SPORT0, SPORT1, and SPORT2 also interface to an off-board connector for communication with other serial devices. For more information, see “SPORT0 Interface” on page 2-4.

The UART of the processor connects to an RS-232 line driver and a DB9 female connector, providing an interface to a PC or other serial device.

Default Configuration

The ADSP-BF538F EZ-KIT Lite board is designed to run outside your personal computer as a stand-alone unit. You do not have to open your computer case.

ADSP-BF538F EZ-KIT Lite Evaluation System Manual 1-3

Default Configuration

When removing the EZ-KIT Lite board from the package, handle the board carefully to avoid the discharge of static electricity, which may 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-BF538F 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.

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.

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-BF538F. Click Next.

ADSP-BF538F EZ-KIT Lite Evaluation System Manual 1-5

Installation and Session Startup

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. In the Select your platform list, select ADSP-BF538F EZ-KIT Lite via Debug Agent. In Session name, highlight or specify the session 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. If you are satisfied, click Finish. If not, click Back to make changes.

1-6 ADSP-BF538F EZ-KIT Lite Evaluation System Manual

To disconnect from a session, click the disconnect button or select Session–>Disconnect from Target.

To delete a session, select Session –> Session List. Select the ses- sion name from the list and click Delete. Click OK.

Using ADSP-BF538F EZ-KIT Lite

Evaluation License Restrictions

• VisualDSP++ allows a connection to the ADSP-BF538F EZ-KIT Lite via the USB debug agent interface only. Connections to simulators and emulation products are no longer allowed.

• The linker restricts a users program to 20 KB of internal memory for code space with no restrictions for data space.

Refer to the VisualDSP++ Installation Quick Reference Card for details.

The EZ-KIT Lite hardware must be connected and powered up to use VisualDSP++ with a valid evaluation or permanent license.

Memory Map

The ADSP-BF538F processor has internal SRAM that can be used for instruction or data storage. SRAM configuration details can be found in the ADSP-BF538/ADSP-BF538F Blackfin Processor Hardware Reference.

The ADSP-BF538F EZ-KIT Lite board includes two types of external memory: SDRAM and flash.

The size of SDRAM is 64 Mbytes (32M x 16-bit). The processor’s memory select pin,

The size of the external flash memory is 4 Mbytes (2M x 16-bits), and the size of the internal flash memory is 1 Mbyte. The processor’s asynchronous memory select pins (~AMS3–0) are configured for flash memory. Any of the ~AMS signals can be mapped to internal or external flash memory.

~SMS0, is configured for SDRAM.
