1 Introduction
The bdiAccess library can be used to access the BDI1000 functions. With this library, a program run-
ning on a Windows/Linux/Unix host can take advantage of the JTAG interface of an ARM based tar-
get 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 BDI1000 to a ARM7TDMI 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 BDI1000
The BDI1000 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 BDI1000 can be updated by the user with a simple Windows based configuration
program. The BDI1000 supports target system voltages from 1.8 up to 5 Volts.

2 Installation
2.1 Connecting the BDI1000 to Target
The enclosed cables to the target system are designed for the ARM Development Boards. In case
where the target system has the same connector layout, the cable (14 pin or 20 pin) can be directly
connected.
In order to ensure reliable operation of the BDI (EMC, runtimes, etc.) the target cable length must not
exceed 20 cm (8").
TARGET A connector signals see table on next page.

TARGET A Connector Signals
The BDI1000 works also with targets which have no dedicated TRST pin. For this kind of targets, the
BDI cannot force the target to debug mode immediately after reset. The target always begins execu-
tion of application code until the BDI has finished programming the Debug Control Register.

1 reserved This pin is currently not used.
2TRST JTAG Test Reset
This open-drain / push-pull output of the BDI1000 resets the JTAG TAP controller on the
target. Default driver type is open-drain. With a special init list entry it can be changed to
push-pull (see online help).

2.1.1 Changing Target Processor Type
Before you can use the BDI1000 with an other target processor type (e.g. ARM <--> PPC), a new
setup has to be done (see chapter 2.6 «Configuration»). During this process the target cable must
be disconnected from the target system. The BDI1000 needs to be supplied between 2.5V and 5V
via the POWER connector. For more information see chapter 2.2.1 «External Power Supply».
To avoid data line conflicts, the BDI1000 must be disconnected from the target system while
programming the logic for an other target CPU.

2.2 Connecting the BDI1000 to Power Supply
2.2.1 External Power Supply
The BDI1000 needs to be supplied between 2.5V and 5V 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 BDI1000, keep the power supply cable as short as possible.
For error-free operation, the power supply to the BDI1000 must be between 2.5V and 5V 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 from Target System
The BDI1000 needs to be supplied between 2.5V and 5V via TARGET A connector. This mode can
only be used when the target system runs between 2.5V and 5V and the pin «Vcc Target» is able to
deliver a current up to:
• [email protected] Target
• [email protected] Target
• [email protected] Target
For pin description and layout see chapter 2.1 «Connecting the BDI1000 to Target». Insert the en-
closed Jumper as shown in figure below. Please ensure that the jumper is inserted correctly.
For error-free operation, the power supply to the BDI1000 must be between 2.5V and 5V DC. The
maximal tolerable supply voltage is 5.25 VDC. Any higher voltage or a wrong polarity might

2.4 Connecting the BDI1000 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).
