JTAG interface library, BDI2000 (MIPS32) Installation Manual 3

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 an MIPS32 based
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 MIPS32 based 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. A/B).

2 Installation
2.1 Connecting the BDI2000 toTarget
The cables to the target system are designed for the IDT RC32300 Development Boards (optional
available: Part# 90070) and for EJTAG 2.5 compatible boards (enclosed). In case where the target
system has the same connector layout, the cable (14 pin or 24 pin) can be directly connected.
In order to ensure reliable operation of the BDI (EMC, runtimes, etc.) the target cable length must not
exceed 25 cm (10").
For BDI MAIN / TARGET A connector signals see table on next page.

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. 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 EJTAGTest 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. ARM <--> MIPS), a new
setup has to be done (see chapter 2.5). 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 5 Volts (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 en-
closed 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).
