1 Introduction
The BDI2000 adds Background Debug Mode features to the CodeWarrior debugger environment
from Metrowerks. With the BDI2000, you control and monitor the microcontroller solely through the
stable on-chip debugging services. You won’t waste time and target resources with a software ROM
monitor, and you eliminate the cabling problems typical of ICE’s. This combination runs even when
the target system crashes and allows developers to continue investigating the cause of the crash.
A RS232 interface with a maximum of 115 kBaud and a 10Base-T Ethernet interface is available for
the host interface.
The configuration software is used to update the firmware and to configure the BDI2000 so it works
with the CodeWarrior debugger.
1.1 BDI2000
The BDI2000 is a processor system in a small box. It implements the interface between the BDM pins
of the target CPU and a 10Base-T Ethernet / RS232 connector. BDI2000 is powered by a MC68360,
512Kbyte RAM and a flash memory of 1024Kbyte. As a result of consistent implementation of lasted
technology, the BDI2000 is optimally prepared for further enhancements. The firmware and the pro-
grammable logic of the BDI2000 can be updated by the user with a simple Windows based configu-
ration program. The BDI2000 supports 1.8 – 5.0 Volts target systems (3.0 – 5.0 Volts target systems
with Rev. A/B).
