Hardware Preparation and Installation

P2 Adapter Preparation

The MVME761 transitio n module uses a three-row or five-r ow P2 adapter to transfer serial, parallel, and Ethernet signals to and from the MVME2700 series VME module.

Three-Row Adapter

On the MVME761-001, three-row P2 adapter, a 50-pin male connector (J2) also carries 8-bit SCSI signals from the MVME2700 board. Preparation of a three-row P2 adapter for the MVME761 consists of installing a j umper on header J1 to enabl e the SCSI terminating resisto rs if necessary. Figure 1-30 illustrates the location of the jumper header and

connectors on the MVME761’s three-row P2 adapter. For basic preparation of the five-row P2 adapter, refer to the next section.

Hardware Preparation and Installation

Hardware Installation

The following sections discuss the placement of mezzanine cards on the MVME2700 base board, the installation of the complete MVME2700 VME module assembly and transi tion module into a VME chassis, and the system considerations relevant to the installation. 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 mezzanine (if applicable), and the optional carrier boa rd for additional PCI expansion (if applicable)—are already in place on the MVME2700. The user-configurable jumpers are accessible with the mezzanines installed.

Should it be neces sary to instal l mezzani nes on t he base board, r efer t o the following sections for a brief description of the installation procedure.

Use ESD

Wrist Strap

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 electrostatic discharge (E SD). After removing the component from its protective wrapper or from the system, place the componen t flat on a grounded, static -free surface (an d, 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 active electrical ground. Note that a system chassis may not be grounded if it is unplugged.

System Considerations

The MVME2700 draws power from VMEbus backplane connectors P1 and P2. P2 is also used for the upper 16 bits o f data in 3 2-bit tr ansfers , and for the upper eight address lines in extended addressing mode. The MVME2700 may not function properly wit hout it s main boar d conn ected to VMEbus backplane connectors P1 and P2.

Whether the MVME2700 operates as a VMEbus master or as a VMEbus slave, it is c onfigured for 3 2 bits of addr ess and 32 bits of dat a (A32/D3 2). However, it handles A16 or A24 devices in th e address ranges. D8 and/ or D16 devices in the system must be handled by the PowerPC software. Refer to the memory maps in Chapter 2, Operating Instructions.

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 $0 0000000, as programmed by the firmware. This may be changed via software to any other base address. Refer to the

MVME2600/2700 Series Single Board Computer Programmer’s Reference Guide for more information.

System Considerations

processor

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 might lack this glob al bus timeout: when the MVME2700 is not the system control ler and there is no global bus timeout elsewher e 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 opera tional status of the proc essor(s). One registe r of the GCSR (global control/st atus register) set in cludes four bits that functi on as location monitors t o allow one MVME2700 processor to broadcast a sig nal to any other MVME2700 processors. All eight registers are accessible from any local processor as well as from the VMEbus.

Hardware Preparation and Installation

The MVME2700 VME module draws +5V DC, +12V DC, and

–12V DC power from the VMEbus backplane through con nect or s P1 and P2. The 3.3V DC and 2.5V DC power is derived on-board from the +5V DC.

MVME2700 VME Module

The MVME2700 VME module furnishes +12V DC and (in MVME761 I/O mode) –12V DC power to the transit ion module through pol yswitches (resettable fu ses) F2 and F 3 respectiv ely. These voltage sour ces power the serial port drivers and any LAN transceivers connected to the transition module. Fused +5V DC power is supplied through polyswitch F1 to the base board’s keyboar d and mouse connectors an d t o t he 14-pin combined LED-mezzanine/remote-reset connector, J1. The MVME2700 front panel illuminates when all three voltages are available.

In MVME712M I/O mode, the yellow DS1 LED on the MVME71 2M also signals the availability of +12V DC LAN power, indicating in turn that polyswitch F2 is good. If the Ethernet transceiver fails to operate, check polyswitch F2.

System Considerations

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

The MVME2700 supplies a

SPEAKER_OUT signal 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 4-1.

On the MVME2700 series VME module, 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 bit per character ❏ Parity disabled (no parity) ❏ Baud rate of 9600 baud

9600 baud is the powe r-up defaul t fo r seria l por ts on MVME27 00 boar ds. After power-up you can reconfigure the baud rate if you wish, using the PPCBug PF (Port Format) 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.

2Operating Instructions

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 firm ware initializa tion process is perf ormed 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 mo dify the firmware configuration before you boot the operating system.

The flowchart in Figure 2-1 shows the basic initialization process that takes place during system startup.

For further information on PPCBug firmware, refer to Chapter 5, PPCBug

Firmware and to the PPCBug Firmware User’s Manual, listed in Appendix D, Related Documentation.

Switches and L EDs

The MVME2700 front panel has ABOR T and RESET switches 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 all resou rces as vi ewed by t he proce ssor (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 MVME2600/2700 Series Single Board Computer Programmer’s Reference Guide, which is also applicable to the MVME2700.

Processor Memory Map

The processor memory map configuration is under the control of the Raven bridge controll er ASIC and the Fal con memo ry cont roller c hip set. The Raven and Falcon devices adjust system mapping to suit a given application via pro grammable map de coder register s. At system powe r-up or reset, a default processor memory map takes over.

Memory Maps

Default Processor Memory Map

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

Single Board Computer Programmer’s Reference Guide.

http://www.motorola.com/computer/literature 2-5

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 P CI memory map exi sts. Resetting the system tur ns 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 MVME2600/2700 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-programmabl e 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 VMEbus mapping, including suggested CHRP- and PREP-compatible memory maps, can be found in the MVME2600/2700 Series Single Board Computer Programmer’s Ref erence Guide. Figure 2-2 shows the overall mapping approach from the standpoint of a VMEbus master.

2-6 Computer Group Literature Center Web Site

Programming Considerations

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

❏ Registers that modify the address map ❏ Registers that require two cycles to access ❏ VMEbus in terrupt request registers

PCI Arbitration

There are seven pot ential PCI bus mas ters on the MVME2700 s ingle board 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 g iven appl ication.

Endian Issues

The PowerPC processo r and the VMEbus are inherent ly big-endi an, while the PCI bus is inherently li tt le -endian. The following sect ion s sum m ari ze how the MVME2700 handles software and hardware differences in bigand little-endian operations. For further details on endian considerations, refer to the M VME2600/2700 Series Single Board Computer Programmer’s Reference Guide.

http://www.motorola.com/computer/literature 2-11

Operating Instructions

Processor/Memory Domain

The MPC750 processor can operate in both big-endian and little-endian mode. However, it always treats the external processor/memory bus as big-endian by performing address rearrangement and reordering when running in little-endia n mo de. The MPC regist er s in the Rav en MPU/ PCI bus bridge controll er ASIC and the Falcon memory con tr oll er chip set, as well as DRAM, ROM/Flash, and system registers, always appear as big-endian.

Role of the Raven ASIC

Because the PCI bus is litt le-endian, the Raven performs byte swap ping 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 tra nsferred 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. Big-endian 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 firs t one to b e t ransf erre d rega rd less of th e endian mode. Since the Raven maintains address invariance in both little-endian and

2-12 Computer Group Literature Center Web Site

Programming Considerations

big-endian mode, no endian issues should arise for Ethernet data. Big-endian software must still take the byte-swapping effect into account when accessing the registers of the PCI/Ethernet device, however.

Role of the Universe II ASIC

Because the PCI bus is li ttle-endian w hile the VMEbus 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 , regard les s of the mode of ope ra tion in th e proces sor’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).

In little-endian mode, however, software must take the byte-swapping effect of the Uni verse II ASI C and the ad dress reverse-rearranging effect of the Raven into account.
