Hard ware Co nfiguration

To produce the desired configuration and ensure proper operation of the MVME2700, you may need to carry out certain hardware modifications before installing the module.

The MVME2700 provides software control over most options: by setting bits in control registers after installing the module in a system, you can modify its confi gurat ion. The M VME27 00 contr ol regi ster s are de scrib ed in Chapter 5, and/or in the MVME2600 Series Single Board Computer Programmer’s Reference Guide listed under Related Documentation.

Some options, however, ar e not software-programma ble. Such options are controlled through manual installation or removal of header jumpers or interface modules on the base board or the associated transition module.

Instructions on preparing the base board, transition modules and P2 adapter are covered in Chapter 2. Installation instructions for the base board, memory mezzanine , transition modu les and P2 adapter are c overed in Chapter 3.

Flash Bank Selection (J9)

The MVME2700 base board has provision for 1MB of 16-bit Flash memory. The RAM200 memory mezzanine acc ommodates 4MB or 8MB of additional 64-bit Flash memory.

The Flash memory is organized in either one or two banks, each bank either 16 or 64 bits wide.

To enable Flash bank A (4MB or 8MB of firmware resident on solderedin devices on the RAM200 mezzanine), place a jumper across header J9 pins 1 and 2. To enable Flash bank B (1MB of firm ware located in soc kets on the base board), place a jumper across header J9 pins 2 and 3.

MVME2700 Base Board Preparation

System Controller Sel ection (J20)

The MVME2700 is factory-c onfigured as a VMEbus sys tem controller by

jumper header J20. If you select the “automatic” system controller function by placing a jumper on J20 pins 2 and 3, the MVME2700 determines wheth er it is t he system cont roller by its posi tion on the b us. If the board is in the fi rs t sl ot from the left, it configures itself as the system controller. If the MVME2700 is not to be system controller under any circumstances, place the jumper on J20 pins 1 and 2. When the board is functioning as system controller, the

MVME712M Transition Module Preparation

P2 Adapter Preparation

In its factory configuration, the MVME712M transition module uses a three-row P2 adapter to transfer synchronous/asynchronous serial, parallel, and Ethernet signals to and from the MVME2700 series VMEmodule. A 50-pin male connector (J 3) on the P2 ad apter carries 8-bit SCSI signals from the MVME2700.

Preparation of the three-row P2 adapter for the MVME712M consists of removing or installing the SCSI termin ating resi stors, R1- R3. Figure 2- 10 illustrates the location of the resistors, the co nnectors, and SCSI t erminator power fuse F1. For further infor mation on the preparatio n of the transition

module and this P2 adapter, refer to the user’s manual for the MVME712M, listed in Related Documentation.

Overview

The following sections discuss the:

Before installing the MVME2700, ensure that the serial ports and all header jumpers are configured as desired.

In most cases, the mezzanine cards—the RAM200 ECC DRAM module, the optional PCI me zza nine (if applicable ), and the opt ional carrier board for additional PCI expansion (if applicable)—are already in place on the MVME2700. The user-configurable jumpers are accessible with the mezzanines installed.

3Hardware Installation

❏ Placement of mezzanine cards on the MVME2700 base board ❏ Installation of the complete MVME2700 VMEmodule assembly

and transition module into a VME chassis

❏ System considerations relevant to the installation

If it is necessary to install mezzanines on the base board, refer to the following sections for a brief description of the installation procedure.

ESD Precautions

Use ESD

Wrist Strap

Motorola strongl y recommends tha t you use an anti static wrist st rap and a conductive foam pad when installing or upgrading the system. Electronic components, such a s disk drive s, comput er boa rds, an d memory modu les, can be extremely sensitive to ESD. After removing the component from the computer 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). Wrap one end of a wrist grounding strap around your wrist.

3-1

Hardware Installation

Attach the grounding end (usually a piece of copper foil or an alligator clip) to an electrical ground. An electrical ground can be a piece of metal that literally runs into the ground (such as an unpainted metal pipe) or a metal part of a ground ed elect rica l appli ance. An appl ia nce is gro unded if it has a three -prong plug and is plu gged into a three-pr ong grounded outlet . You cannot use the computer itself as a ground, because it is unplugged when you work on it.

Important Cautions and Warnings

The following cautions and warning apply to all installation procedures described in this chap ter.

Inserting or removin g modules with power appli ed may result

in damage to module components.

Caution

Warning

Caution

Dangerous voltages, capable of causing death, are present in this equipment. Use extreme caution when handling, testing, and adjusting.

Avoid touching areas of integrated circuitry; static discharge can damage these circuits.

System Considerations

The MVME2700 draws power from VMEbus backplane connectors P1 and P2. P2 is also used for the upp er 16 bit s of data i n 32-bit transfe rs, and for the upper 8 address lines in extended addressing mode. The MVME2700 may not function prope rly without its main board conn ect ed to VMEbus backplane connectors P1 and P2.

Whether the MVME2700 operates as a VMEbus master or as a VMEbus slave, it is configu red for 32 bit s of a ddress a nd 32 bi ts of data ( A32/D32). However, it handle s A16 or A24 de vices in t he address ranges indi cated in Chapter 2. D8 and/or D16 devices in the system must be handled by the

PowerPC The MVME2700 contains shared onboard DRAM and secondary cache

memory whose base address is software-selectable. Both the onboard processor and offboard VMEbus devices see this local DRAM at base physical address $00000000, as programmed by the firmware. This may be changed via software to any other base address. Refer to the MVME2600 Series Single Board Computer Programmer’s Reference Guide for more information.

processor software. Refer to the memory maps in Chapter 4.

System Considerations

If the MVME2700 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 MVME2700 waits forever for the VMEbus cycle to complete. This causes the system to lock up. There is only one situation when the system mi ght lack this g lobal bus timeout: when the MVME2700 is not the system contr oller and there is no glo bal bus timeout els ewhere in the system.

Multiple MVME2700s may be installed in a single VME chassis. In general, hardware multiprocessor features are supported.

Other MPUs on the VMEbus can interrupt, disable, communicate with, and determine the op erational status of the processor(s). One regis ter of the GCSR (global control/ status register) set in cludes four bits that fun ction as location monit ors to allow one MVME2700 proces sor to broadcast a signal to any other MVME2700 processors. All eight registers are accessible from any local processor as well as from the VMEbus.

http://www.mcg.mot.com/literature 3-17

Hardware Installation

The MVME2700 VMEmodule draws +5Vdc, +12Vdc, and

–12Vdc power from the VMEbus backplane through connectors P1 and P2. The 3.3Vdc and 2.5Vdc power is derived on-board from the +5Vdc.

MVME2700 VMEmodule

The MVME2700 VMEmodule furnishes +12Vdc and (in MVME761 I/O mode) –12Vdc power to the transition module through polyswitches (resettable f uses) F2 a nd F3 respect ively. The se voltage s ources power the serial port drivers and any LAN transceivers connected to the transition module. Fused +5Vdc powe r is supplied through pol yswitch F1 to the base board’s keyboard and mouse connectors and t o the 14-pin combine d LEDmezzanine/remote-reset connector, J1. The MVME2700 front panel illuminates when all three voltages are available.

In MVME712M I/O mode, the yellow DS1 LED o n the MVME712M also signals th e availability of +12Vdc LAN power, indicating in t urn that polyswitch F2 is good. If the Ethernet transceiver fails to operate, check polyswitch F2.

In MVME712M I/O mode, the MVME2700 supplies SCSI terminator power through a 1A fuse (F1) loc at ed on t he P2 adapt er boar d. If the fuse is blown, the SCSI device(s) may function erraticall y or not at all. With the P2 adapter board cabled to a transition module and with an SCSI bus connected to the transition module, the green illuminates when SCSI termin ator power is availabl e. If the

Note Because any device on the SCSI bus can provide the

In MVME761 I/O mode, the MVME2700 suppli es SCSI terminator power through a polyswitch (resettable fuse) located on the P2 adapter board.

3-18 Computer Group Literature Center Web Site

System Considerations

The MVME2700 supplies a SPEAKER_OUT signa l to the 14-pin combined LED-mezzanine/remote-reset connector, J1. When J1 is used as a remote reset connector with the LED mezzanine removed, the

SPEAKER_OUT

signal can be cabled to an external speaker. For the pin assignments of J1, refer to Table 6-1 on page 6-3.

On the MVME2700 series VMEmodule, the standard serial console port COM1, accessible through the transition module, serves as the firmware console port. The firmware console should be set up as follows:

❏ Eight bits per character ❏ One stop b it per character ❏ Parity disabled (no parit y) ❏ Baud rate of 9600 baud

9600 baud is t he po wer- up def ault fo r ser ial ports on MVME2700 boards . After power-up you can reconfigure the baud rate if you wish, using the PPCBug PF (Port Forma t) command via the command line interface.

Whatever the baud rate, some type of hardware handshaking — either XON/OFF or via the RTS/CTS line — is desirable if the system supports it.

Overview

This chapter supplies information for use of the MVME2700 series of single-board computers in a system configuration. Here you will find the power-up procedure and descriptions of the switches and LEDs, memory maps, and software initialization.

Power-up the System

After you have verified that all necessary hardware preparation has been done, that all connections have been made correctly, and that the installation is complete, you can power up the system. The MPU, hardware, and fi rmware initiali zation process is p erformed by the PPCBug firmware at power-up or system reset. The firmware initializes the devices on the MVME2700 module in preparation for booting the operating system.

The firmware is shipped from the factory with an appropriate set of defaults. In most cases there is no need to modify t he firmware configuration before you boot the operating system.

The flowchart in Figure 4-1 shows the basic initializa tion process that takes place during system startup.

For further information on PPCBug firmware, refer to Chapter 7 and to

Appendix D or to the PPCBug Firmware User’s Manual.

Switches and LEDs

The MVME2700 front panel has ABOR T and RESET switche s and six LED (light-emitting diode) status indicators ( The switches and LEDs are mounted on an LED mezzanine board that plugs into the base board.

Memory Maps

There are three points of view for memory maps:

❏ The mapping of al l resou rces as viewed b y the pr ocessor (MPU bus

memory map)

❏ The mapping of onboard resources as viewed by PCI local bus

masters (PCI bus memory map)

❏ The mapping of onboard resources as viewed by VMEbus masters

(VMEbus memory map)

The following sections give a general description of the MVME2700 memory organization from the above three points of view. Detailed memory maps can be found in the MVME2600 Series Single Board Computer Programmer’s Refer ence Guide , which is also applicable to the MVME2700.

Processor Memory Map

The processor memory map configuration is under the control of the Raven bridge control ler ASI C and the Falcon me mory cont roll er chip set. The Raven and Falcon devices adjust system mapping to suit a given application via programmable map de coder regis ters. At syst em power-up or reset, a default processor memory map takes over.

4-4 Computer Group Literature Center Web Site

Default Processor Memory Map

The default processo r memory map that is valid at power-up or reset remains in ef fect until reprogrammed for specific applications. Table 4-2 defines the entire default map ($00000000 to $FFFFFFFF).

2. The first 1MB of ROM/Flash bank A (socketed 1MB ROM/Flash)

appears in this range after a reset if the rom_b_rv control bit in the

Falcon’s ROM B Base/Size register is cleared. If the rom_b_rv control bit is set, this address range maps to ROM/Flash bank B (soldered 4MB or 8MB ROM/Flash).

For detailed processor memory maps, including suggested CHRP- and PREP-compatible memory maps, refer to the MVME2600 Series Single Board Computer Programmer’s Reference Guide.

http://www.mcg.mot.com/literature 4-5

Operating Instructions

PCI Local Bus Memory Map

The PCI memory map is controlled by the Raven MPU/PCI bus bridge controller ASIC and by the Universe II PCI/VME bus bridge ASIC. The Raven and Universe devices adjust system mapping to suit a given application via programmable map decoder registers.

No default PCI memory map exists. Resetting the system turns the PCI map decoders off, and they must be reprogrammed in software for the intended application.

For detailed PCI memory maps, including suggested CHRP- and PREPcompatible memory maps , refer to the MVME2600 Series Single Board Computer Programmer’s Reference Guide.

VMEbus Memory Map

The VMEbus is programmable. Like other segments of the MVME2700 memory map, the mapping of local resources as viewed by VMEbus masters varies among applications.

The Universe II PCI/VME bus bridge ASIC includes a user-progr ammable map decoder for the VMEbus-to-local-bus interface. The address translation capabilities of the Universe II enable the processor to access any range of addresses on the VMEbus.

Recommendations for VMEbu s mapping, including suggested CHRP- and PREP-compatible memory maps, can be found in the MVME2600 Series Single Board Computer Programmer’s Reference Guide. The following figure shows the overall mapping approach from the standpoint of a VMEbus master.

Programming Considerations

Good programming practice dictates that only one MPU at a time have control of the MVME2700 control registers. Of particular note are:

PCI Arbitration

There are seven potential PCI bus masters on the MVME2700 singleboard computer:

❏ Raven ASIC (MPU/PCI bus bridge controller)

❏ Winbond W83C553 PIB (PCI/ISA bus bridge controller) ❏ DECchip 21140 Ethernet controller ❏ SYM53C825A SCSI controller ❏ Universe II ASIC (PCI/VME bus bridge controller) ❏ PMC Slot 1 (PCI mezzanine card) ❏ PMCspan (PCI expansion)

The Winbond W83C553 PIB device supplies the PCI arbitration support for these seven types of devices. The PIB supports flexible arbitration modes of fixed priority, rotating priority, and mixed priority, as appropriate in a given a pplication. Details on PCI a rbitratio n can be f ound in the MVME2600 Series Single Board Computer Programmer’s Reference Guide.

Interrupt Handling

The Raven ASIC, which contr ol s PHB (PCI Host Bridge) MPU/local bus interface functions on the MVME2700, performs interrupt handling as well. Sources of interrupts may be any of the following:

❏ The Raven ASIC itself (timer or transfer error interrupts) ❏ The processor (processor self-interrupts) ❏ The Falco n chip set (me mory error in terrupts) ❏ The PCI bus (interrupts from PCI devices) ❏ The ISA bus (interrupts from ISA devices)

Endian Issues

The PowerPC processo r and th e VMEbus are in herently big- endian, while the PCI bus is inherentl y li tt le-endian. The following sections summarize how the MVME2700 handles software and hardware differences in bigand little-endian operations.

Processor/Memory Domain

The MPC750 processor can operate in both big-endian and little-endian mode. However, it always tre ats the external process or/memory bus as bigendian by performing address rearrangement and reordering when running in little-en dian mode. The MPC registers in the Raven MPU/PCI

http://www.mcg.mot.com/literature 4-11

Operating Instructions

bus bridge controller ASIC and the Fal con me mory con tr oll er chip set, as well as DRAM, ROM/Flash, and system registers, always appear as bigendian.

Role of the Raven ASIC

Because the PCI bus is lit tle-endia n, the Raven performs byt e swapping in both directions (from PCI to memory and from the processor to PCI) to maintain address invariance while programmed to operate in big-endian mode with the processor and the memory subsystem.

In little-endian mode , the Raven reverse-rearranges the address for PCIbound accesses and rearranges the address for memory-bound accesses (from PCI). In this case, no byte swapping is done.

PCI Domain

The PCI bus is inherently little-endian. All devices connected directly to the PCI bus operate in little-endian mode, regardless of the mode of

operation in the processor’s domain.

PCI and SCSI

SCSI is byte-stream-oriented; the byte having the lowest address in memory is the first one to be transferred regardless of the endian mode. Since the Raven ASIC maintains address invariance in both little-endian and big-endian modes, no endian issues should arise for SCSI data. Bigendian software must still take the byte-swapping effect into account when accessing the registers of the PCI/SCSI device, however.

PCI and Ethernet

Ethernet is also byte-stream-oriented; the byte having the lowest address in memory is t he fi rst one t o b e tra nsfer red r egard les s of the endi an mode. Since the Raven maintain s address invariance in both little-endi an and bigendian mode, no endian issues should arise for Ethernet data. Big-endian software must still take the byte-sw apping effect into account when accessing the registers of the PCI/Ethernet device, however.

4-12 Computer Group Literature Center Web Site

Role of the Universe II ASIC

Because the PCI bus is little-endian while the VMEb us is big-endian, the Universe PCI/VME bus bridge ASIC performs byte swapping in both directions (from PCI to VMEbus and from VMEbus to PCI) to maintain

address invariance , reg ardles s of t he mode of ope rati on in the proc essor ’s domain.

VMEbus Domain

The VMEbus is inherently big-endian. All devices connected directly to the VMEbus must operate in big-endian mode, regardless of the mode of operation in the processor’s domain.

In big-endian mode, byte-swapping is performed first by the Universe II ASIC and then by the Raven. The result is transparent to big-endian software (a desirable effect).

Programming Considerations

In little-endian mode, however, software must take the byte-swapping effect of th e Univer se II ASIC and th e addre ss rev erse- rea rrangi ng e ffect of the Raven into account.

Functional Description

SCSI Interface

The MVME2700 VMEmodule suppor ts mass storag e subsystems th rough the industry-standard SCSI bus. These subsystems may include hard and floppy disk drives, str eaming ta pe drive s, and other mass storage de vic es. The SCSI interface is im plemented using the Symbios 53C82 5A SCSI I/O controller at a clock speed of 40MHz. The SCSI I/O controller connects directly to the PCI local bus.

MVME712M-compatible versions of the MVME2700 route the SCSI lines through the P2 connector to the MVME712M transition module, as illustrated in Figure 3-4. The SCSI control lines have filter networks to minimize the effects of VMEbus signal noise at P2.

In the MVME761-compatible version, the SCSI lines are routed through the P2 connector up to connecto r J2 on th e P2 adapter board, as il lustrat ed in Figure 3-5. The MVME761 itself has no SCSI support, however, SCSI devices are suppor ted via t he use of a thre e- row or fiv e-row adapte r board included with the MVME761 transition board.

The SCSI bus is 16 bits wide in syst ems that support the VME64 extensi on (those equipped with 5-row, 160-pin VME backplane connectors). The SCSI bus is 8 bits wid e in VME systems with three -row backplanes. Re fer to the MVME712M Transition Module and P2 Adapter Board Inst allation and Use manual for the pin assignments of the SCSI connectors used on the transition module. Refer to the Symbios 53C825A data manual for detailed programming information.

SCSI Termination

The individual configuring the system must ensure that the SCSI bus is properly terminated at both ends.

In MVME712M I/O mode, the base board uses the sockets provided for SCSI bus terminators on th e three-r ow P2 adapter boa rd supplied with the MVME712M. If the SCSI bus ends at the adapter board, termination resistors must b e i nst al le d there. +5Vdc power to t he SCSI bus signal and termination resistors is supplied through a fuse located on the adapter board. The five-row P2 adapter, MVME761P2-011 is compatible with the MVME712M for s upport of 16-bit SCSI a nd PMC I/O. It requires a five-row backplane.

In MVME761 I/O mode, the P2 adapter board used with the MVME761 has a jumper to enable/disable SCSI bus terminators. +5Vdc power for SCSI termination is supplied through a polyswitch located on the adapter board.

Ethernet Inte rface

The MVME2700 VMEmodule uses Digi ta l Equi pmen t’ s DEC2114 0 PCI Fast Ethernet LAN controller to implement an Ethernet interface that supports both AUI (via MVME712M) and 10Base-T/100Base-TX (via MVME761) connections. The balanced differential transceiver lines are coupled via on-board transformers.

The MVME2700 routes its AUI or 10Base-T/100Base-TX lines through the P2 connector to the t ransition module (as i ll ust ra ted in Figure 3-4 and

Figure 3-5). The MVME712M front panel has an ind ustry-stan dard DB15

connector for an AUI connection. The MVME761 supports 10BaseT/100Base-TX connections.

Every MVME2700 is assigned an Et hernet s tation addre ss. The addre ss is $08003E2xxxxx, where xxxxx is the unique 5-nibble number assigned to the board (every board has a different value for xxxxx).

Each MVME2700 displays its Ether net stat ion address on a label attache d to the base board in the PMC co nnecto r keepou t area just b ehind t he front panel. In addition, the six byt es incl udi ng the Ethernet station addr ess are

stored in the NVRAM (BBRAM) configuration area specified by boot ROM. That is, the value 08003E2xxxxx is stored in NVRAM. At an address of $FFFC1F2C, the upper four bytes (08003E2x) can be read. At an address of $FFFC1F30, the lower two bytes (xxxx) can be read. The MVME2700 debugger (the PPCBug firmware) has the capability to retrieve or set the Ethernet station address.

If the data in NVRAM is lost, use the number on the label in the PMC connector keepout area to restore it.

For the pin assignments of the transition module AUI or 10Base-

T/100Base-TX connector , refer t o the user’ s manual for the MVME712M or MVME761. Refer to the BBRAM/TOD Clock memory map description in the MVME2600 Series Single Board Computer Programmer’s Reference Guide for detailed programming information.

PCI Mezzanine Interface

A key feature of th e MVME2700 family is the PCI ( Peripheral Component Interconnect) bus. In addition to the on-board local bus devices (SCSI, Ethernet, graphics, etc.), the PCI bus supports an industry-standard mezzanine interface, IEEE P1386.1 PMC (PCI Mezzanine Card).

PMC modules offer a variety of possibilities for I/O expansion through FDDI (Fiber Distributed Data Interface), ATM (Asynchronous Transfer Mode), graphics, Ethernet, or SCSI ports. The base board supports PMC front panel and rear P2 I/O. There is also provision for stacking a PMC carrier board on the base board for additional expansion.

The MVME2700 supports one PMC slot. Four 64-pin connectors on the base board (J11, J12, J13, and J14) interface with 32-bit IEEE P1386.1 PMC-compatible mezzanines to add any desirable function. The PCI Mezzanine Card slot has the following characteristics:

the PMC connectors. For detailed programming information, refer to the PCI bus descriptions in the MVME2600 Series Programmer’s Reference Guide and to the user documentation for the PMC modules you intend to use.

VMEbus Interface

The VMEbus interface is implemented with the CA91C142 ‘Universe II ASIC. The Universe chip interfaces the 32/64-bit PCI local bus to the VMEbus. The Universe II ASIC provides:

❏ The PCI-bus-to-VMEbus interface ❏ The VMEbus-to-PCI-bus interface ❏ The DMA controller functions of the local VMEbus

The Universe II chip includes Universe Control and Status Registers (UCSRs) for interprocessor communications. It can provide the VMEbus system controller functions as well. For detailed programming information, refer to the Universe II User’s Manual and to the di scussions

in the MVME2600 Series Programmer's Reference Guide.

ISA Super I/O Device (ISASIO)

The MVME2700 uses a PC87308 ISASIO chip from National Semiconductor to implement certain segments of the P2 and front-panel I/O:

❏ Two asynchronous serial ports (COM1 and COM2) via P2 and

transition module

❏ Parallel port via P2 and transition module:

– Centronics printer port in MVME712M-compatible models – IEEE1284 bidirectional parallel port in MVME761-compatible
