Introduction

NOTE: The DEV-BF548DA-Lite has an on-board Debug Agent, which is not available on the DEV-BF548-

Lite Board. All other features are identical! In this document, when describing both boards, the name

DEV-BF548-Lite is used.

The DEV-BF548-Lite Development Board with integrated Debug Agent is designed as a development

and application board for the high performance ADSP-BF548 based CM-BF548 Core Module. Special

feature of the board is the 10/100Mbit industrial Ethernet controller. The integrated Debug Agent is a

USB based debug interface which enables programming and debugging of the Blackfin Core Modules.

It is fully compatible with the Visual DSP++ development environment. The development board

provides all interfaces on dedicated connectors or expansion connectors. Extender boards can be

plugged on top of the Development Board in order to enable additional interfaces.
