JTAG debug interface for SeeCode™ Debugger, BDI2000 (PPC744x/745x) User Manual 3
© Copyright 1999-2003 by ABATRON AG V 1.00
1 Introduction
The BDI2000 adds JTAG based debug features to Metaware’s Seecode debugger.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 SeeCode 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
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 toTarget
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.

BDITARGET B Connector Signals:
Pin Name Describtion
1 TDO JTAGTest Data Out
This input to the BDI2000 connects to the target TDO pin.
2 IO0 General purpose I/O
This output of the BDI2000 connects to the target QACK pin. Currently not used.
3 TDI JTAGTest Data In
This output of the BDI2000 connects to the target TDI pin.
4 TRST JTAGTest Reset
This output of the BDI2000 resets the JTAG TAP controller on the target.
5 IN0 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.

2.1.1 ChangingTarget ProcessorType
Before you can use the BDI2000 with an other target processor type (e.g. ARM <--> 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 BDI OPTION connec-
tor (Version A) or via the POWER connector (Version B). 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:
