PREFACE

Thank you for purchasing the ADSP-BF561 EZ-KIT Lite®, Analog Devices, Inc. evaluation system for Blackfin

The Blackfin processors are embedded processors that support a Media Instruction Set Computing (MISC) architecture. This architecture is the natural merging of RISC, media functions, and digital signal processing (DSP) characteristics towards delivering signal processing performance in a microprocessor-like environment.

The evaluation board is designed to be used in conjunction with the VisualDSP++ ADSP-BF561 Blackfin processors. The VisualDSP++ development environment gives you the ability to perform advanced application code development and debug, such as:

development environment to test the capabilities of the

• Create, compile, assemble, and link application programs written in C++, C and ADSP-BF561 assembly

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

• Read and write data and program memory

• Read and write core and peripheral registers

processors.

• Plot memory

Access to the ADSP-BF561 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-BF561 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

http://www.analog.com/dsp/tools/.

ADSP-BF561 EZ-KIT Lite provides example programs to demonstrate the capabilities of the evaluation board.

The board features:

The ADSP-BF561 EZ-KIT Lite installation is part of the VisualDSP++ installation. The EZ-KIT Lite is a licensed product that offers an unrestricted evaluation license for the first 90 days. Once the initial unrestricted 90-day evaluation license expires:

• VisualDSP++ allows a connection to the ADSP-BF561

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 41 KB of internal

memory for code space with no restrictions for data space.

The EZ-KIT Lite board holds 8 MB of flash memory, which can be used to store user-specific boot code, allowing the board to run as a stand-alone unit. The board also holds 512-Mb SDRAM, which can be used at runtime. For more information see “External Memory” on page 1-6.

ADSP-BF561 EZ-KIT Lite Evaluation System Manual xi

Purpose of This Manual

SPORT0 interfaces with the AD1836A audio codec, allowing you to create

audio signal processing applications.

SPORT0 also attaches to an off-board

connector to allow communication with other serial devices. For information about

SPORT0, see “SPORT0 Audio Interface” on page 2-3.

The Parallel Peripheral Interfaces (PPIs) of the processor connect to both a video encoder and video decoder, allowing you to create video signal processing applications. For information on how the board utilizes the processor’s PPIs, see “PPI Interfaces” on page 2-6.

The UART of the processor connects to an RS232 Line Driver and a male connector, allowing you to interface with a PC or other serial device. For information about the UART, see “UART Port” on page 2-8.

Additionally, the EZ-KIT Lite board provides access to most of the processor’s peripheral ports. Access is provided in the form of a three-connector expansion interface. For information about the expansion interface, see “Expansion Interface” on page 2-8.

Purpose of This Manual

The ADSP-BF561 EZ-KIT Lite Evaluation System Manual provides instructions for installing the product hardware (board). The text describes the operation and configuration of the board components and provides guidelines for running your own code on the ADSP-BF561 EZ-KIT Lite. Finally, a schematic and a bill of materials are provided as a reference for future designs.

The product software installation is detailed in the VisualDSP++ Installa- tion Quick Reference Card.

Default Configuration

The ADSP-BF561 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.

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, DIP switch, connector locations, and LEDs used in installation. Confirm that your board is set up in the default configuration before using the board.

Installation and Session Startup

Using EZ-KIT Lite

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 ( USB connector) is lit. This signifies that the board is communicating properly with the host PC and is ready to run VisualDSP++.

2. From the Start menu, navigate to the VisualDSP++ environment via the Programs menu. If you are running VisualDSP++ for the first time, the New Session dialog box appears on the screen (skip the rest of the procedure and go to step 3). If you have run VisualDSP++ previously, the last opened session appears on the screen. To switch to another session, via the Session List dialog box, hold down the Ctrl key while starting VisualDSP++ (go to step 5).

3. In Debug target, select Blackfin Emulators/EZ-KIT Lites. In Platform, select the appropriate EZ-KIT Lite via a debug agent (ADSP-BF561 EZ-KIT Lite via Debug Agent). In Session name, type a new name or accept the default.

Evaluation License Restrictions

• VisualDSP++ allows a connection to the ADSP-BF561 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 41 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.

External Memory

EZ-KIT Lite board includes two types of external memory, 64-MB SDRAM and 8-MB flash. Table 1-1 shows the memory map of these devices. The complete configuration of the ADSP-BF561 processor internal SRAM is detailed in Figure 1-2.
