This manual includes hardware preparation and installation instructions for the MVME2400-series module, information about using the front panel, a functional description, information about programming the board, using the PPCBug debugging firmware, and advanced debugger topics. Other appendices provide the MVME2400-series specifications, connector pin assignments, and a glossary of terms. Additional manuals you may wish to obtain are listed in Appendix A, Ordering Related Documentation.

The information in this manual applies principally to the MVME2400-series module. The PMCspan and PMCs are described briefly here but are documented in detail in separate publications, furnished with those products. Refer to the individual product documentation for complete preparation and installation instructions. These manuals are listed in Appendix A, Ordering Related Documentation.

This manual is intended for anyone who wants to design OEM systems, supply additional capability to an existing compatible system, or work in a lab environment for experimental purposes. A basic knowledge of computers and digital logic is assumed.

Document Terminology

Throughout this manual, a convention is used which precedes data and address parameters by a character identifying the numeric format as follows:

	$	Dollar	Specifies a hexadecimal character
	0x	Zero-x
	%	Percent	Specifies a binary number
	&	Ampersand	Specifies a decimal number

For example, “12” is the decimal number twelve, and “$12” (hexadecimal) is the equivalent of decimal number eighteen. Unless otherwise specified, all address references are in hexadecimal.

An asterisk (*) following the signal name for signals which are level-significant denotes that the signal is true or valid when the signal is low.

An asterisk (*) following the signal name for signals which are edge-significant denotes that the actions initiated by that signal occur on high-to-low transition.

In this manual, assertion and negation are used to specify forcing a signal to a particular state. In particular, assertion and assert refer to a signal that is active or true; negation and negate indicate a signal that is inactive or false. These terms are used independently of the voltage level (high or low) that they represent.

Data and address sizes are defined as follows:

Byte	8 bits, numbered 0 through 7, with bit 0 being the least significant.
Half word	16 bits, numbered 0 through 15, with bit 0 being the least significant.
Word	32 bits, numbered 0 through 31, with bit 0 being the least significant.
Double word	64 bits, numbered 0 through 63, with bit 0 being the least significant.

Safety Summary

Safety Depends On You

The following general safety precautions must be observed during all phases of operation, service, and repair of this equipment. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture, and intended use of the equipment. Motorola, Inc. assumes no liability for the customer’s failure to comply with these requirements.

The safety precautions listed below represent warnings of certain dangers of which Motorola is aware. You, as the user of the product, should follow these warnings and all other safety precautions necessary for the safe operation of the equipment in your operating environment.

Ground the Instrument.

To minimize shock hazard, the equipment chassis and enclosure must be connected to an electrical ground. The equipment is supplied with a three-conductor AC power cable. The power cable must be plugged into an approved three-contact electrical outlet. The power jack and mating plug of the power cable meet International Electrotechnical Commission (IEC) safety standards.

Do Not Operate in an Explosive Atmosphere.

Do not operate the equipment in the presence of flammable gases or fumes. Operation of any electrical equipment in such an environment constitutes a definite safety hazard.

Keep Away From Live Circuits.

Operating personnel must not remove equipment covers. Only Factory Authorized Service Personnel or other qualified maintenance personnel may remove equipment covers for internal subassembly or component replacement or any internal adjustment. Do not replace components with power cable connected. Under certain conditions, dangerous voltages may exist even with the power cable removed.

Preparing and Installing the

MVME2400-Series Module 1

Introduction

This chapter provides a brief description of the MVME2400-Series VME Processor Module, and instructions for preparing and installing the hardware.

In this manual, the name MVME240x refers to all models of the

MVME2400-series boards, unless otherwise specified.

MVME240x Description

The MVME2400-series VME processor module is a PCI Mezzanine Card (PMC) carrier board. It is based on the PowerPC™ 750 microprocessor, MPC750.

Two front panel cutouts provide access to PMC I/O. One double-width or two single-width PMCs can be installed directly on the MVME240x. Optionally, one or two PMCspan PCI expansion mezzanine modules can be added to provide the capability of up to four additional PMC modules.

Two RJ45 connectors on the front panel provide the interface to 10/100Base-T Ethernet, and to a debug serial port.

The following list is of equipment that is appropriate for use in an

MVME240x system:

PMCspan PCI expansion mezzanine module

Peripheral Component Interconnect (PCI) Mezzanine Cards (PMC)s

VMEsystem enclosure

System console terminal

Disk drives (and/or other I/O) and controllers

Operating system (and/or application software)

MVME240x Module

The MVME240x module is a powerful, low-cost embedded VME controller and intelligent PMC carrier board. The MVME240x is currently available in the configurations shown in Table 1-1.

The MVME240x includes support circuitry such as ECC SDRAM, PROM/Flash memory, and bridges to the Industry Standard Architecture (ISA) bus and the VMEbus. The MVME240x’s PMC carrier architecture allows flexible configuration options and easy upgrades. It is designed to support one or two PMCs, plus one or two optional PCI expansion mezzanine modules that each support up to two PMCs. It occupies a single VMEmodule slot, except when optional PCI expansion mezzanine modules are also used:

	MVME2433-1		128MB ECC SDRAM	Scanbe Handles
	MVME2433-3		128MB ECC SDRAM	1101-1 Handles

The MVME240x interfaces to the VMEbus via the P1 and P2 connectors, which use the new 5-row 160-pin connectors as specified in the proposed VME64 Extension Standard. It also draws +5V, +12V, and -12V power from the VMEbus backplane through these two connectors. The +3.3V and 2.5V power, used for the PCI bridge chip and possibly for the PMC mezzanine, is derived onboard from the +5V power.

MVME240x Description

Support for two IEEE P1386.1 PCI mezzanine cards is provided via eight 64-pin SMT connectors. Front panel openings are provided on the MVME240x board for the two PMC slots.

In addition, there are 64 pins of I/O from PMC slot 1 and 46 pins of I/O from PMC slot 2 that are routed to P2. The two PMC slots may contain two single-wide PMCs or one double-wide PMC. There are also two RJ45 connectors on the front panel: one for the Ethernet 10BaseT/100BaseTX interface, and one for the async serial debug port. The front panel also includes reset and abort switches and status LEDs.

PMCspan Expansion Mezzanine

An optional PCI expansion mezzanine module or PMC carrier board, PMCspan, provides the capability of adding two additional PMCs. Two PMCspans can be stacked on an MVME240x, providing four additional PMC slots, for a total of six slots including the two onboard the MVME240x. Table 1-2 lists the PMCspan models that are available for use with the MVME240x.

	Table 1-2. PMCspan Models
Expansion Module	Description
PMCSPAN-002	Primary PCI expansion mezzanine module. Allows two PMC modules
	for the MVME240x. Includes 32-bit PCI bridge.
PMCSPAN-010	Secondary PCI expansion mezzanine module. Allows two additional
	PMC modules for the MVME240x. Does not include
	32-bit PCI bridge; requires a PMCSPAN-002.

PCI Mezzanine Cards (PMCs)

The PMC slots on the MVME240x board are IEEE P1386.1 compliant. P2 I/O-based PMCs that follow the PMC committee recommendation for PCI I/O when using the 5-row VME64 extension connector will be pin-out compatible with the MVME240x.

Preparing and Installing the MVME2400-Series Module

The MVME240x board supports both front panel I/O and rear panel P2 I/O through either PMC slot 1 or PMC slot 2. 64 pins of I/O from slot 1 and 46 pins of I/O from slot 2 are routed directly to P2.

VMEsystem Enclosure

Your MVME240x board must be installed in a VMEsystem chassis with both P1 and P2 backplane connections. It requires a single slot, except when PMCspan carrier boards are used. Allow one extra slot for each PMCspan.

System Console Terminal

In normal operation, connection of a debug console terminal is required only if you intend to use the MVME240x’s debug firmware, PPCBug, interactively. An RJ45 connector is provided on the front panel of the MVME240x for this purpose.

Preparing the MVME240x Hardware

To produce the desired configuration and ensure proper operation of the MVME240x, you may need to carry out certain modifications before and after installing the modules.

The following paragraphs discuss the preparation of the MVME240x hardware components prior to installing them into a chassis and connecting them.

MVME240x

The MVME240x provides software control over most options; by setting bits in control registers after installing the MVME240x in a system, you can modify its configuration. The MVME240x control registers are briefly described in Chapter 4, with additional information in the MVME2400Series VME Processor Module Programmer’s Reference Guide as listed in the table Motorola Computer Group Documents in Appendix A, Ordering Related Documents.

Preparing and Installing the MVME2400-Series Module

Some options, however, are not software-programmable. Such options are controlled through manual installation or removal of header jumpers or interface modules on the MVME240x or the associated modules.

Figure 1-1 illustrates the placement of the switches, jumper headers, connectors, and LED indicators on the MVME240x. Manually configurable items on the MVME240x include:

Flash memory bank A/bank B reset vector (J8)

VMEbus system controller selection header (J9)

General-purpose software-readable header (S3)

The MVME240x has been factory tested and is shipped with the configurations described in the following sections. The MVME240x factory-installed debug monitor, PPCBug, operates with those factory settings.

Setting the Flash Memory Bank A/Bank B Reset Vector Header (J8)

Bank B consists of 1 MB of 8-bit Flash memory in two 32-pin PLCC 8-bit sockets.

Bank A consists of four 16-bit devices that are populated with 16Mbit Flash devices (8 MB). A jumper header, J8, associated with the first set of four Flash devices provides a total of 64KB of hardware-protected boot block. Only 32-bit writes are supported for this bank of Flash. The address of the reset vector is jumper-selectable. A jumper must be installed either between J8 pins 1 and 2 for Bank A factory configuration, or between J8 pins 2 and 3 for Bank B. When the jumper is installed, the SMC (System Memory Controller) of the Hawk ASIC maps 0xFFF00100 to the Bank B sockets..

	J8					J8
1					1
2					2
3					3
Bank A (factory configuration)					Bank B

Setting the VMEbus System Controller Selection Header (J9)

The MVME240x is factory-configured in automatic system controller mode; i.e., a jumper is installed across pins 2 and 3 of header J9. This means that the MVME240x determines if it is system controller at system power-up or reset by its position on the bus; if it is in slot 1 on the VME system, it configures itself as the system controller.

Remove the jumper from J9 if you intend to operate the MVME240x as system controller in all cases.

Install the jumper across pins 1 and 2 if the MVME240x is not to operate as system controller under any circumstances.

Setting the General-Purpose Software-Readable Header (SRH) Switch(S3)

Switch S3 is an eight pole single-throw switch with software readable switch settings. These settings can be read as a register at ISA I/O address $801 (hexadecimal). Each switch pole can be set to either logic 0 or logic 1. A logic 0 means the switch is in the “ON” position for that particular bit. A logic 1 means the switch is in the “OFF” position for that particular bit. SRH Register Bit 0 is associated with Pin 1 and Pin 16 of the SRH, and SRH Register Bit 7 is associated with Pin 8 and Pin 9 of the SRH. The SRH is a read-only register.

If Motorola’s PowerPC firmware, PPCBug, is being used, it reserves all bits, SRH0 to SRH7. If it is not being used, the switch can be used for other applications.

PMCs

For a discussion of any configurable items on the PMCs, refer to the user’s manual for the particular PMCs.

PMCspan

You will need to use an additional slot in the VME chassis for each PMCspan expansion module you plan to use. Before installing a PMCspan on the MVME240x, you must install the selected PMCs on the PMCspan. Refer to the PMCspan PMCAdapter Carrier Module Instllation and Use manual for instructions.

System Console Terminal

Ensure that the switches are set in the proper position for all bits on switch S3 of the MVME240x board as shown in Figure 1-2. This is necessary when the PPCBug firmware is used. Connect the terminal via a cable to the RJ45 DEBUG connector J2. See Table C-3 for pin signal assignments. Set up the terminal as follows:

–Eight bits per character

–One stop bit per character

–Parity disabled (no parity)

–Baud rate = 9600 baud (default baud rate of the port at powerup); after power-up, you can reconfigure the baud rate with PPCBug’s PF command

Installing the MVME240x Hardware

The following paragraphs discuss installing PMCs onto the MVME240x, installing PMCspan modules onto the MVME240x, installing the MVME240x into a VME chassis, and connecting an optional system console terminal.

ESD Precautions

Motorola strongly recommends that you use an antistatic wrist strap and a conductive foam pad when installing or upgrading a system. Electronic components, such as disk drives, computer boards, and memory modules, can be extremely sensitive to Electro-Static Discharge (ESD). After removing the component from the system or its protective wrapper, place the component flat on a grounded, static-free surface (and in the case of a board, component side up). Do not slide the component over any surface.

If an ESD station is not available, you can avoid damage resulting from ESD by wearing an antistatic wrist strap (available at electronics stores) that is attached to an unpainted metal part of the system chassis.

PMCs

PCI mezzanine card (PMC) modules mount on top of the MVME240x module, and/or on a PMCspan. Refer to Figure 1-3 and perform the following steps to install a PMC on your MVME240x module. This procedure assumes that you have read the user’s manual that came with your PMCs.

1.Attach an ESD strap to your wrist. Attach the other end of the ESD strap to the chassis as a ground. The ESD strap must be secured to your wrist and to ground throughout the procedure.

2.Perform an operating system shutdown. Turn the AC or DC power off and remove the AC cord or DC power lines from the system. Remove chassis or system cover(s) as necessary for access to the VMEmodules.
