Page 3: Introduction
BDI2000 so it works with the EDGE debugger. 1.1 BDI2000 The BDI2000 is a processor system in a small box. It implements the interface between the JTAG pins of the target CPU and a 10Base-T Ethernet / RS232 connector. The firmware and the program- mable logic of the BDI2000 can be updated by the user with a simple Windows based configuration... -

User Manual 4 JTAG debug interface for EDGE Debugger, BDI2000 (PPC6xx/7xx/82xx/83xx) 2 Installation 2.1 Connecting the BDI2000 to Target The cable to the target system is a 16 pin flat ribbon cable. In case where the target system has an appropriate connector, the cable can be directly connected. - Page 5 3.0 – 5.0V with Rev. B : This input to the BDI2000 is used to detect if the target is powered up. If there is a current limiting resistor between this pin and the target Vdd, it should be 100 Ohm or less.

Page 6: Changing Target Processor Type
2.1.1 Changing Target Processor Type Before you can use the BDI2000 with an other target processor type (e.g. CPU32 <--> PPC), a new setup has to be done (see Appendix A). During this process the target cable must be disconnected from the target system. -
Page 7: Connecting The Bdi2000 To Power Supply
2.2 Connecting the BDI2000 to Power Supply The BDI2000 needs to be supplied with 5 Volts (max. 1A) via the POWER connector. The available power supply from Abatron (option) or the enclosed power cable can be directly connected. In order to ensure reliable operation of the BDI2000, keep the power supply cable as short as possible. -

Page 12: Configuration
First make sure that the BDI is properly connected (see Chapter 2.1 to 2.4). The BDI must be con- nected via RS232 to the Windows host. To avoid data line conflicts, the BDI2000 must be disconnected from the target system while programming the logic for an other target CPU (see Chapter 2.1.1). - Page 13 This button is only active if there is a newer firmware or logic version present in the execution directory of the BDI setup software. Press this button to write the new firmware and/or logic into the BDI2000 flash mem- ory / programmable logic.

Page 14: Init List
In order to prepare the target for debugging, you can define an Initialization List. This list is stored in the Flash memory of the BDI2000 and worked through every time the target comes out of reset. Use it to get the target operational after a reset. The memory system is usually initialized through this list. - Page 15 User Manual 15 JTAG debug interface for EDGE Debugger, BDI2000 (PPC6xx/7xx/82xx/83xx) 8006 Write to this special register with a value of 1, if the BDI should use the alternate single step mode. The alternate mode does not use the trace bit (MSR[SE]) to implement single step- ping.
