Additional manuals you may wish to obtain are listed in Appendix A, Ordering Related Documentation.

The information in this man ual appl ies principally to the MVME2400-se ri es module . The PMCspan and PMCs are described briefly here but are documented in detail in separate publications, furni shed with thos e products. Refer to the indi vidual produc t documentation for complete preparation and installation instructions. These manuals are listed in Appendix A, Ordering Related Documentation.

This manual is intended for anyon e who want s to design OEM systems, supply additiona l capability to an existi ng compatible syste m, 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 i s used which pr ecedes dat a and addres s parameters by a character identifying the numeric format as follows:

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

Specifies a hexadecimal character

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

An asterisk (*) following the signal na me for signals which are level-si gnificant denotes that the signal is true or valid when the signal is low.

An asterisk (*) following the signal na me 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 i s acti ve or t rue; negat ion and negate indicate a sign al tha t is in activ e or fal se. These te rms are u sed i ndepend ently 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 , wit h 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.

Introduction

This chapter provide s a brief description of t he 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 VM E processor mod ule is a PCI Mezzan ine Card

(PMC) carrier board. It is based on the PowerPC™ 750 microprocessor, MPC750.

Two front panel cutouts provi de acce ss to PMC I/ O. One doubl e-wid th 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)

Preparing and Installing the MVME2400-Series Module

MVME240x Module

The MVME240x module is a powerful, low-cost embedded VME controller and i ntelligent PMC carr ier board. The MVME240x is curr ently 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 oc cupies a single VMEmodule slot, except when optional PCI expansion mezzanine modules are also used:

Table 1-1. MVME240x Models

Model MPC Memory Handles

32MB ECC SDRAM Scanbe Handles

The MVME240x interfaces t o the VMEbus via th e P1 and P2 connect ors, which use the new 5-row 160-p in c onne ct ors as specified in the propos ed VME64 Extension Standard. It also draws +5V, +12V, and -12V power from the VMEbus backplane through these two con nectors. 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.

1-2 Computer Group Literature Center Web Site

Support for two IEEE P1386.1 PCI mezza nine car ds is pro vided vi a 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 ro uted to P2. The two PMC slo ts 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.

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 commi ttee recommendat ion for PCI I/O when using the 5-row VME64 extension connector will be pin-out compatible with the MVME240x.

http://www.mcg.mot.com/literature 1-3

Preparing and Installing the MVME2400-Series Module

The MVME240x board supports both front panel I/ O and rear panel P 2 I/O through either PMC slot 1 o r PMC slot 2. 64 pins o f 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.

http://www.mcg.mot.com/literature 1-7

The MVME240x provides software control over most options; by setting bits in control registers after installing the MVME24 0x in a system, you can modify its configurati on. The MVME240x control registe rs are briefly described in Chapter 4, with additional information in the MVME2400- Series VME Processor Module Programme r’s Reference Guide as listed in the table Motorola Computer Group Documents in Appendix A, Order ing Related Documents.

Preparing and Installing the MVME2400-Series Module

Some options, however, are not sof tware-programmabl e. 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-bi t sockets.

Bank A consists of four 16-bit devices that are populated with 16Mbit Flash devices (8 MB). A j umper header, J8, associ ated with the f irst set of four Flash devices provides a total of 64KB of hardware-protected boot block. Only 32-bit wri tes are sup ported for thi s bank of Fla sh. The address of the reset vector is jumper-selectable. A jumper must be inst al le d ei the r 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..

Setting the VMEbus System Controller Selection Header (J9)

The MVME240x is factory-configured in automatic sy stem controller mode; i.e., a jumper is installed across pins 2 and 3 of header J9. This means that the MVME240x determi nes if it is system co ntr oller at sys tem 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 softwa re 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 l ogic

1. A logic 0 means th e switch is in the “ON” position for that particula r bit. A logic 1 means the switch is i n the “OFF” positi on for t hat par ticu lar bit. SRH Register Bit 0 is associated with Pin 1 and Pin 16 of the SRH, and SRH Register Bit 7 i s 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 it ems 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 us e. Before installing a PMCspan on the MVME240x, you must install t he selecte d PMCs on the PMCspan. Refer to the PMCspan PMCAdapter Carrier Module Instllation and Use manual for instructions.

System Console Terminal

Ensure that the switc hes are set in the proper positi on 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 ter minal via a cable to th e RJ45 DEBUG connector J2. See Table C- 3 for pin sign al assignment s. 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 power-

up); 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 a ntistatic wrist stra p and a conductive foam pad when installing or upgrading a system. Electronic components, such as d isk dr ives, c omputer boards , and memor y modules , can be extremely sensitive to Electro-Static Discharge (ESD). After removing the component fr om th e system or its protective wrapper, place the component flat o n 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 othe r end of t he 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.
