1 Introduction
The bdiAccess library can be used to access the BDI2000 functions. With this library, a program run-
ning on a Windows/Linux/Unix host can take advantage of the JTAG interface of a PPC6xx/7xx/82xx/
83xx target processor and execute the following tasks:
• Read/Write target registers
• Read/Write target memory
• Reset/Startup target
• Flash programming
• Start/Stop program execution
This Installation Manual shows how to connect the BDI2000 to a PowerPC target and how to install
the bdiAccess software. The interface to the library is defined in a different document that is target
independent.
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
program. The BDI2000 supports 1.8 – 5.0 Volts target systems (3.0 – 5.0 Volts target systems with
Rev. B).

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. The pin assignment is in accordance with
the PowerPC COP connector specification.
In order to ensure reliable operation of the BDI (EMC, runtimes, etc.) the target cable length must not
exceed 20 cm (8").
For BDI TARGET B connector signals see table on next page.

BDI TARGET B Connector Signals:
Pin Name Describtion
1TDO JTAG Test Data Out
This input to the BDI2000 connects to the target TDO pin.
2IO0 General purpose I/O
This output of the BDI2000 connects to the target QACK pin. Currently not used.
3TDI JTAG Test Data In
This output of the BDI2000 connects to the target TDI pin.
4TRST JTAG Test Reset
This output of the BDI2000 resets the JTAG TAP controller on the target.
5IN0 General purpose Input
This input to the BDI2000 connects to the target HALTED pin. Currently not used.
6 Vcc Target 1.8 – 5.0V:
This is the target reference voltage. It indicates that the target has power and it is also used
to create the logic-level reference for the input comparators. It also controls the output logic
levels to the target. It is normally fed from Vdd I/O on the target board.
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.
7TCK JTAG Test Clock
This output of the BDI2000 connects to the target TCK pin.

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. The BDI2000 needs to be supplied with 5 Volts via the POWER connector.
For more information see chapter 2.2.1 «External Power Supply».
To avoid data line conflicts, the BDI2000 must be disconnected from the target system while
programming the logic for an other target CPU.

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.
For error-free operation, the power supply to the BDI2000 must be between 4.75V and 5.25V DC.
The maximal tolerable supply voltage is 5.25 VDC. Any higher voltage or a wrong polarity
might destroy the electronics.
Please switch on the system in the following sequence:
• 1 --> external power supply
• 2 --> target system

2.4 Connecting the BDI2000 to the Host
2.4.1 Serial line communication
The host is connected to the BDI through the serial interface (COM1...COM4). The communication
cable between BDI and Host is a serial cable (RXD / TXD are crossed). There is the same connector
pinout for the BDI and for the Host side (Refer to Figure below).

2.4.2 Ethernet communication
The BDI2000 has a built-in 10 BASE-T Ethernet interface (see figure below). Connect an UTP (Un-
shilded Twisted Pair) cable to the BD2000. For thin Ethernet coaxial networks you can connect a
commercially available media converter (BNC-->10 BASE-T) between your network and the
BDI2000. Contact your network administrator if you have questions about the network.
The following explains the meanings of the built-in LED lights:

LI Link When this LED light is ON, data link is successful between the UTP
port of the BDI2000 and the hub to which it is connected.
TX Transmit When this LED light BLINKS, data is being transmitted through the UTP
