  • Page 3: Introduction

    The BDI2000 is a processor system in a small box. It implements the interface between the BDM/ JTAG pins of the target CPU and a 10Base-T Ethernet / RS232 connector. BDI2000 is powered by a MC68360, 512Kbyte RAM and a flash memory of 1024Kbyte. As a result of consistent implementa- tion of lasted technology, the BDI2000 is optimally prepared for further enhancements.

  • Page 4: Installation

    JTAG interface for SeeCode™ Debugger, BDI2000 (XScale) User Manual 2 Installation 2.1 Connecting the BDI2000 to Target The enclosed target cable is designed for the Intel recommended 20pin JTAG connector. In case where the target system has an appropriate connector, the cable can be directly connected. The pin assignment is in accordance with the Intel specification.
  • Page 5 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.

  • Page 6: 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. XScale <--> PPC), a new setup has to be done (see Appendix A). During this process the target cable must be disconnected from the target system.

  • Page 7: Connecting The Bdi2000 To Power Supply

    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 enclosed power cable can be directly connected.

    JTAG interface for SeeCode™ Debugger, BDI2000 (XScale) User Manual 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).

  • 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

    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 BDI2000 must be disconnected from the target system while programming the logic for an other target CPU (see Chapter 2.1.1).
  • Page 14 This button is only active if there is a newer firmware or logic version present in the execution directory of the BDI setup software. Press this button to write the new firmware and/or logic into the BDI2000 flash mem- ory / programmable logic.

  • Page 15: Init List

    In order to prepare the target for debugging, you can define an Initialization List. This list is stored in the Flash memory of the BDI2000 and worked through every time the target comes out of reset. Use it to get the target operational after a reset. The memory system is usually initialized through this list.
