  • Page 3: Introduction

    Ethernet (10 BASE-T) 1.1 BDI2000 The BDI2000 is the main part of the bdiGDB system. This small box implements the interface be- tween the JTAG pins of the target CPU and a 10Base-T Ethernet connector. The firmware and the programmable logic of the BDI2000 can be updated by the user with a simple Windows based con- figuration program.

  • Page 4: Bdi Configuration

    User Manual 1.2 BDI Configuration As an initial setup, the IP address of the BDI2000, the IP address of the host with the configuration file and the name of the configuration file is stored within the flash of the BDI2000.

  • Page 5: Installation

    User Manual 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 COP connector specification.
  • Page 6 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.

  • Page 7: Changing Target Processor Type

    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 chapter 2.5). During this process the target cable must be disconnected from the target system.

  • Page 8: Connecting The Bdi2000 To Power Supply

    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.

  • Page 9: Status Led «Mode

    MODE LED BDI STATES The BDI is ready for use, the firmware is already loaded. 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).

    BDI2000 (PowerPC 7440/7450/86xx) User Manual 2.4 Connecting the BDI2000 to Host 2.4.1 Serial line communication Serial line communication is only used for the initial configuration of the bdiGDB system. The host is connected to the BDI through the serial interface (COM1...COM4). The communication cable (included) between BDI and Host is a serial cable.

  • Page 11: Ethernet Communication

    User Manual 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.

  • Page 13: Configuration With A Linux / Unix Host

    2.5.1 Configuration with a Linux / Unix host The firmware / logic update and the initial configuration of the BDI2000 is done with a command line utility. In the ZIP Archive bdisetup.zip are all sources to build this utility. More information about this utility can be found at the top in the bdisetup.c source file.
  • Page 14 The following parameters are used to configure the BDI: BDI IP Address The IP address for the BDI2000. Ask your network administrator for as- signing an IP address to this BDI2000. Every BDI2000 in your network needs a different IP address.
