  • Page 3: Introduction

    A RS232 interface with a maximum of 115 kBaud and a 10Base-T Ethernet interface is available for the host interface. The bdiHCI setup software is used to update the firmware and to configure the BDI2000 so it works with the HI-WAVE debugger.

  • Page 4: Installation

    BDM interface for HI-WAVE™ Debugger, BDI2000 (CPU16/32) User Manual 2 Installation 2.1 Connecting the BDI2000 to Target The cable to the target system is a ten 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 Motorola 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. CPU32 <--> PPC), a new setup has to be done (see Appendix A). During this process the target cable must be disconnected from the target system.

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 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.
