bdi RDIJTAG interface for RDI Debuggers, BDI1000User Manual 3© Copyright 1999-2003 by ABATRON AG V 1.101 IntroductionThe BDI1000 adds JTAG based debugging to RDI compatible debuggers (e.g. ADW from ARM Ldt).With the BDI1000, you control and monitor the microcontroller solely through the stable on-chip de-bugging services. You won’t waste time and target resources with a software ROM monitor, and youeliminate the cabling problems typical of ICE’s. This combination runs even when the target systemcrashes and allows developers to continue investigating the cause of the crash. A RS232 interfacewith 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 BDI1000 so it workswith the RDI compatible debugger.1.1 BDI1000The BDI1000 is a processor system in a small box. It implements the interface between the JTAGpins of the target CPU and a 10Base-T Ethernet / RS232 connector. BDI1000 is powered by aMC68331, 256Kbyte RAM and a flash memory of 512Kbyte. As a result of consistent implementationof lasted technology, the BDI1000 is optimally prepared for further enhancements. The firmware andthe programmable logic of the BDI1000 can be updated by the user with a simple Windows basedconfiguration program. The BDI1000 supports target system voltages from 1.8 up to 5 Volts.PC HostRDIDebuggerBDI1000AAAAbbbbaaaattttrrrroooonnnn AAAAGGGG SSSSwwwwiiiissssssss MMMMaaaaddddeeeeTarget SystemJTAG InterfaceEthernet (10 BASE-T)BDI1000AAAAbbbbaaaattttrrrroooonnnn AAAAGGGG SSSSwwwwiiiissssssss MMMMaaaaddddeeeeTarget SystemJTAG InterfaceRS232ARM ARM
