1 Introduction

The BDI2000 adds JTAG based debug features to the EDGE debugger environment from Mentor

Graphics.. 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 moni-

tor, 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 toupdate the firmware and to configure the 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

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 4xx JTAG 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.

Pin Name Describtion

1TDO JTAG Test Data Out

This input to the BDI2000 connects to the target TDO pin.

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.

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 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 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

2.3 Status LED «MODE»

The built in LED indicates the following BDI states:

MODE LED BDI STATES

OFF The BDI is ready for use, the firmware is already loaded.

ON The power supply for the BDI2000 is < 4.75VDC.

BLINK The BDI «loader mode» is active (an invalid firmware is loaded or loading firmware is active).

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

port of the BDI2000
