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.

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

2.6 BDI1000 Setup/Update
First make sure that the BDI is properly connected (see Chapter 2.1 to 2.4). The BDI must be con-
nected via RS232 to the Windows host.
To avoid data line conflicts, the BDI1000 must be disconnected from the target system while
programming the logic for an other target CPU (see Chapter 2.1.1).
2.6.1 Linux/Unix Hosts
In order to update the firmware / logic of the BDI and to set the network parameters, a setup tool is
included for Linux/Unix hosts. In the ZIP Archive bdisetup.zip are all sources to build this utility.
This command line utility can be used to update the firmware and logic of the BDI2000. It is also used
to transfer the network configuration. There are 4 tasks the utility can process:
• Reading the current loaded firmware / logic version
• Erasing the firmware and logic
• Updating the firmware and logic
• Storing the network configuration parameters into the BDI flash
Every of this task is started by executing the setup utility with different parameters. The first param-
eter always selects the task to execute:
bdisetup { -v | -e | -u | -c } [additional parameters]
-v Read version
-e Erase firmware and logic
-u Update firmware and/or logic
-c Store network configuration
There are two common additional parameters which define the serial port and the serial baudrate:
-pP Port to use, replace P with the port to use e.g. /dev/ttyS0
-bB Baudrate to use, replace B with 9, 19, 38, 57 or 115
Additional parameters for update (-u):
-aA Application type, replace A with GDB, ADA, TOR or ACC
-tT Target type, replace T with CPU32,PPC400,PPC600,PPC700,MPC800,
ARM,TRICORE,MCF,HC12 or MCORE
-dD Replace D with the directory with the firmware/logic files
Additional parameters for network configuration (-c):
-iI Replace I with the BDI IP address (format: xxx.xxx.xxx.xxx)
-mM Replace M with the subnet mask.
A subnet mask of 255.255.255.255 disables the gateway function
-gG Replace G with the default gateway IP address
All parameters have default values. See function main(). You may adjust this default values for your
convenience. See also bdisetup.c and document BDIACC.PDF for additional information
To build the setup utility use: gcc bdisetup.c bdidll.c -o bdisetup

BDI IP Address Enter the IP address for the BDI1000. Use the following format:
xxx.xxx.xxx.xxx e.g.151.120.25.101
Ask your network administrator for assigning an IP address to this
BDI1000. Every BDI1000 in your network needs a different IP address.
Subnet Mask Enter the subnet mask of the network where the BDI is connected to.
Use the following format: xxx.xxx.xxx.xxxe.g.255.255.255.0
A subnet mask of 255.255.255.255 disables the gateway feature.
Ask your network administrator for the correct subnet mask.
Default Gateway Enter the IP address of the default gateway. Ask your network administra-
tor for the correct gateway IP address. If the gateway feature is disabled,
you may enter 255.255.255.255 or any other value.
Transmit Click on this button to store the configuration in the BDI1000 flash
memory.
2.6.3 Recover procedure
In rare instances you may not be able to load the firmware in spite of a correctly connected BDI (error
of the previous firmware in the flash memory). Before carrying out the following procedure, check
the possibilities in Appendix «Troubleshooting». In case you do not have any success with the
tips there, do the following:
• Switch OFF the power supply for the BDI and open the unit as
described in Appendix «Maintenance»
• Place the jumper in the «INIT MODE» position
• Connect the power cable or target cable if the BDI is powered
from target system
• Switch ON the power supply for the BDI again and wait until the
LED «MODE» blinks fast
• Turn the power supply OFF again
• Return the jumper to the «DEFAULT» position
• Reassemble the unit as described in Appendix «Maintenance»
