  • Page 71: Overview Of M68000 Firmware

    The firmware for the M68000-based (68K) series of board and system level products has a common genealogy, deriving from the debugger firmware currently used on all Motorola M68000-based CPU modules. The M68000 firmware family provides a high degree of functionality and user friendliness, and yet stresses portability and ease of maintenance.
  • Page 72 162Bug, depending on the outcome of the user program. If you have used one or more of Motorola's other debugging packages, you will find the CISC 162Bug very similar. Some effort has also been made to make the interactive commands more consistent.

  • Page 73: 162Bug Implementation

    162Bug Implementation 162Bug Implementation MVME162Bug is written largely in the ‘‘C’’ programming language, providing benefits of portability and maintainability. Where necessary, assembler has been used in the form of separately compiled modules containing only assembler code — no mixed language modules are used. Physically, 162Bug is contained in a single 27C040 DIP EPROM installed in socket XU2, providing 512KB (128K longwords) of storage.
  • Page 74 Debugger General Information Models with no VMEbus interface have a jumper between pins 7-8 as well. These readable jumpers are read as a register (at $FFF4202D) on the Memory Controller (MC2chip) ASIC. The bit values are read as a zero when the jumper is installed, and as a one when the jumper is removed.
  • Page 75 Installation and Startup Note that when the MVME162LX comes up in a cold reset, 162Bug runs in Board Mode. Using the Environment ( ) or commands can make 162Bug run in System Mode. MENU Refer to Appendix A for details. 2.
  • Page 76 Debugger General Information After power-up, you can reconfigure the baud rate of the debug port if necessary by using the 162Bug firmware’s Port Format (PF) command. Note In order for high-baud rate serial communication between 162Bug and the terminal to work, the terminal must do some form of handshaking.

  • Page 81: Reset

    Restarting the System The debugger has a special feature available for reset conditions. You activate it by pressing the switches at the RESET ABORT same time, releasing first, then releasing seven RESET ABORT seconds later. This ‘‘double-button reset’’ feature instructs the debugger to use the default setup/operation parameters in ROM versus your setup/operation parameters in NVRAM.

    Debugger General Information For this reason, abort is most appropriate when terminating a user program that is being debugged. Abort should be used to regain control if the program gets caught in a loop, etc. The target PC, register contents, etc., help to pinpoint the malfunction.

  • Page 85: Disk I/O Support

    Disk I/O Support Disk I/O Support 162Bug can initiate disk input/output by communicating with intelligent disk controller modules over the VMEbus. Disk support facilities built into 162Bug consist of command-level disk operations, disk I/O system calls (only via one of the TRAP #15 instructions) for use by user programs, and defined data structures for disk parameters.

  • Page 86: Device Probe Function

    These following 162Bug commands are provided for disk I/O. Detailed instructions for their use are found in the Debugging Package for Motorola 68K CISC CPUs User's Manual. When a command is issued to a particular controller LUN and device LUN, these LUNs are remembered by 162Bug so that the next disk command defaults to use the same controller and device.

  • Page 87: Iot (I/O Teach)

    Disk I/O Support IOT (I/O Teach) allows you to change any configurable parameters and attributes of the device. In addition, it allows you to see the controllers available in the system. IOC (I/O Control) allows you to send command packets as defined by the particular controller directly.
  • Page 88 Refer to the system call descriptions in the Debugging Package for Motorola 68K CISC CPUs User's Manual for details on the format and construction of these standardized user packets. The packets which a controller module expects to be given vary from controller to controller.

    Network I/O Support specifically tailored for the disk drive controller it is sent to. Refer to documentation on the particular controller module for the format of its packets, and for using the command.

The first phase allows the diskless remote node to discover its network identify and the name of the file to be booted. The second phase has the diskless remote node reading the boot file across the network into its memory.

  • Page 91: Rarp/Arp Protocol Modules

    Network I/O Support RARP/ARP Protocol Modules The Reverse Address Resolution Protocol (RARP) basically consists of an identity-less node broadcasting a ‘‘whoami’’ packet onto the Ethernet, and waiting for an answer. The RARP server fills an Ethernet reply packet up with the target's Internet Address and sends it.

    Debugger General Information Network I/O Error Codes 162Bug returns an error code if an attempted network operation is unsuccessful. Multiprocessor Support The MVME162LX dual-port RAM feature makes the shared RAM available to remote processors as well as to the local processor. This can be done by either of the following two methods.

(Any remote processor could examine the MPCR contents.) If the code being executed in dual-port RAM is to reenter the debug monitor, a TRAP #15 call using function $0063 (SYSCALL .RETURN) returns control to the monitor with a new display prompt.

    Preserving the Debugger Operating Environment Exception Vector Tables Notice in the preceding example that the value of the target stack pointer register (A7) has not changed even though a trace exception has taken place. Your program may either use the exception vector table provided by 162Bug or it may create a separate exception vector table of its own.

  • Page 112: Creating A New Vector Table

    Using the 162Bug Debugger Creating a New Vector Table Your program may create a separate vector table in memory to contain its exception vectors. If this is done, the program must change the value of the VBR to point at the new vector table. In order to use the debugger facilities you can copy the proper vectors from the 162Bug vector table into the corresponding vector locations in your program vector table.
  • Page 113 Preserving the Debugger Operating Environment It may turn out that your program uses one or more of the exception vectors that are required for debugger operation. Debugger facilities may still be used, however, if your exception handler can determine when to handle the exception itself and when to pass the exception to the debugger.
