  • Page 81 Installation Instructions If the MVME162LX tries to access offboard resources in a nonexistent location and is not system controller, and if the system does not have a global bus timeout, the MVME162LX waits forever for the VMEbus cycle to complete. This will cause the system to lock up. There is only one situation in which the system might lack this global bus timeout: when the MVME162LX is not the system controller and there is no global bus timeout elsewhere in the system.

  • Page 82: Figure 2-2. Db25-Dte-To-Rj45 Adapter

    Hardware Preparation and Installation The controller uses two Zilog Z85230 serial port controllers to implement the four serial communications interfaces. Each interface supports CTS, DCD, RTS, and DTR control signals as well as the TXD and RXD transmit/receive data signals. Because the serial clocks are omitted in the controller’s implementation, serial communications are strictly asynchronous.

    (e.g., "GO"), then control may or may not return to the162Bug, depending on the outcome of the user’s 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 87: Installation And Start-Up

    Installation and Start-up Installation and Start-up Even though the 162Bug is installed on the MVME162LX Embedded Controller, you must follow the steps listed below in order for the 162Bug to operate properly with the controller. To prevent damage to the controller’s components, do not insert or remove the controller while power is applied.
  • Page 88 Debugger General Information J11 Pins Description Bit #0 (GPI0) When this bit is a one (high), it instructs the debugger to use local Static RAM for its work page (i.e., variables, stack, vector tables, etc.). Bit #1 (GPI1) When this bit is a one (high), it instructs the debugger to use the default setup/operation parameters in flash memory or ROM versus the user setup/operation parameters in Non- Volatile RAM (NVRAM).
  • Page 89 Installation and Start-up 4. Connect the terminal that is to be used as the 162Bug system console to the default debug EIA-232-D port at serial port 1 on the front panel of the controller. Refer to Chapter 2 for other connection options.

    As shipped from the factory, the 162Bug occupies an EPROM installed in socket XU24. This leaves three sockets (XU21 - XU23) and the flash available for your use. Contact your Motorola sales office for assistance. This function is configured/enabled by the Environment (ENV) command...

  • Page 92: Network Boot

    For complete details on how to use ROMboot, refer to the Debugging Package for Motorola 68K CISC CPUs User’s Manual. Network Boot Network Auto Boot is a software routine contained in the 162Bug Flash/PROM that provides a mechanism for booting an operating system using a network (local Ethernet interface) as the boot device.

  • Page 93: Restarting The System

    Restarting the System Restarting the System You can initialize the system to a known state in three different ways: reset, abort, and break. Each has characteristics which make it more appropriate than the others in certain situations. The debugger has a special feature upon a reset condition. This feature is activated by depressing the RESET and ABORT switches at the same time.

  • Page 94: Abort

    Debugger General Information Abort Abort is invoked by pressing and releasing the ABORT switch on the controller’s front panel. Whenever Abort is invoked when executing a user program (running target code), a "snapshot" of the processor state is captured and stored in the target registers. For this reason, abort is most appropriate when terminating a user program that is being debugged.

  • Page 95: Mpu Clock Speed Calculation

    Memory Requirements After debugger initialization is done and none of the above situations have occurred, the SYSFAIL* line is negated. This indicates to the user or VMEbus masters the state of the debugger. In a multi-computer configuration, other VMEbus masters could view the pertinent control and status registers to determine which CPU is asserting SYSFAIL*.

  • Page 96: Terminal Input/Output Control

    Debugger General Information The 162Bug requires 2KB of NVRAM for storage of board configuration, communication, and booting parameters. This storage area begins at $FFFC16F8 and ends at $FFFC1EF7. The 162Bug also requires a minimum of 64KB of contiguous read/write memory to operate. The ENV command controls where this block of memory is located.

  • Page 97: Disk I/O Support

    Disk I/O Support When observing output from any 162Bug command, the XON and XOFF characters which are in effect for the terminal port may be entered to control the output, if the XON/XOFF protocol is enabled (default). These characters are initialized to ^S and ^Q respectively by 162Bug, but you may change them with the PF command.

    Network I/O Support RARP/ARP Protocol Modules The Reverse Address Resolution Protocol (RARP) 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.

  • Page 104: Multiprocessor Support

    Debugger General Information Multiprocessor Support The MVME162LX Embedded Controller 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. Either method can be enabled/disabled by the ENV command as its Remote Start Switch Method (refer to Appendix A).
  • Page 105 Multiprocessor Support The status codes that may be set by the bus master are: ASCII G (HEX 47) Use Go Direct (GD) logic specifying the MPAR address. ASCII B (HEX 42) Install breakpoints using the Go (G) logic. The Multiprocessor Address Register (MPAR), located in shared RAM location of $804 offset from the base address the debugger loads it at, contains the second of two longwords used to control communication between processors.

  • Page 106: Gcsr Method

    Debugger General Information 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. Note that every time the debug monitor returns to the prompt, an R is moved into the MPCR to indicate that control can be transferred once again to a specified RAM location.
