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 BDM/
JTAG 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 implementa-
tion of lasted technology, the BDI2000 is optimally prepared for further enhancements.The firmware
and the programmable 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.A/B).

2 Installation
2.1 Connecting the BDI2000 toTarget
The enclosed target cable is designed for the Intel recommended 20pin JTAG connector. In case
where the target system has an appropriate connector, the cable can be directly connected.The pin
assignment is in accordance with the Intel specification.
In order to ensure reliable operation of the BDI (EMC, runtimes, etc.) the target cable length must not
exceed 20 cm (8").

BDI MAIN /TARGET A Connector Signals
Note:
The BDI actively drives TRST.It does not require any special power-up circuitry. Simply, the require-
ment is that TRST is weakly pulled down at the processor. It is suggested that the value of the pull-
down resistor is 10k or greater.

8 TDI JTAGTest Data In
This output of the BDI2000 connects to the target TDI line.
9 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 connected to Vdd I/O on the target board.
3.0 – 5.0V with Rev. A/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.
10 TDO JTAGTest Data Out
This input to the BDI2000 connects to the target TDO line.

2.1.1 ChangingTarget ProcessorType
Before you can use the BDI2000 with an other target processor type (e.g.XScale <--> 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 (Rev. A) or via the POWER connector (Rev. B/C). 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
2.2.1 External Power Supply
The BDI2000 needs to be supplied with 5Volts (max.1A) via the BDI OPTION connector (Rev.A) or
via POWER connector (Rev.B/C).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

2.2.2 Power Supply fromTarget System
The BDI2000 needs to be supplied with 5 Volts (max. 1A) via BDI MAIN target connector (Rev. A) or
via TARGET A connector (Rev. B/C).This mode can only be used when the target system runs with
5V and the pin «Vcc Target» is able to deliver a current up to 1A@5V. For pin description and layout
see chapter 2.1 «Connecting the BDI2000 toTarget».Insert the enclosed Jumper as shown in figure
below. Please ensure that the jumper is inserted correctly .
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.

2.4 Connecting the BDI2000 to 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).
