Serial Port 4 Transmit Clock Receiver Buffer Control (J20)

As described in other sections, a complete configuration of Serial Port 4 requires that you set the following jumper headers on the MVME2603/2604 or the transition module:
J16 (Serial Port 4 receive clock configuration) on MVME712M-
compatible versions of the base board
J17 (Serial Port 4 transmit clock configuration)J20 (Serial Port 4 transmit clock receiver buffer control) on
MVME712M-compatible versions of the base board
J15 on the MVME712M transition modu le or J3 on the MVME761
(Serial Port 4 clock configuration)
A transmit clock receiver buffer (controlled by header J20) is associated with Serial Port 4. Inst alling a jumper on J20 enabl es the buffer. Removing the jumper disables the buffer. The factory configuration has the Serial Port 4 buffer enabled.
J20 remains open on MVME761-compatible versions. On MVME712M­compatible versions, J20 is set in tandem with J17 to configure the Serial Port 4 transmit clock. If one deviates from the factory configuration, so must the other.

System Controller Selection (J22)

The MVME2603/2604 is factory-configured as a VMEbus system controller by jumper header J22. If you select the “automatic” system controller function by placing a jumper on J22 pins 2 and 3, the MVME2603/2604 determines whether it is the system controller by its position on t he bus. If the board is in the first slot from the left, it configures its elf as the s ystem controll er. If the MVME26 03/2604 is n ot to be system controller under any circumstances, place the jumper on J22 pins 1 and 2. When the board is func tioning as system controll er, the LED is turned on.

Remote Status and Control

The MVME2603/2604 front panel LEDs and switches are mounted on a removable mezzanine board. Removing the LED mezzanine makes the mezzanine connector (J 1, a keyed double -row 14-pin co nnector) avai lable for service as a remot e status and control c onnector. In this ap plicati on, J1 can be connected to a user-supplied external cable to carry the Reset and Abort signals and the LED lines to a control panel located apart from the MVME2603/2604. Maximum cable length is 15 feet.

Hardware Installation

The following sections discuss the placement of mezzanine cards on the MVME2603/2604 base board, the installation of the complete MVME2603/2604 VME module assembly and transition module into a VME chassis, and the system considerations relevant to the installation. Before installing th e MVME2603/2604, e nsure 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 MVME2603/2604. The user-conf igurable jumpers ar e accessible with the mezzanines installed.

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.

P2 is also use d f or t he upper 16 bits of data in 32- bit transfers, and for the upper eight address lines in extended addressing mode. The MVME2603/2604 may not function properly without its main board connected to VMEbus backplane connectors P1 and P2.
Whether the MVME2603/2604 operates as a VMEbus master or as a VMEbus slave, it is configured for 32 bits of address and 32 bits of data (A32/D32). However, it handles A16 or A24 device s in the add ress ranges indicated in Chapte r 2, Operating Instructions. D8 and/or D16 devices in the system must be handle d by th e Power P C proc es sor sof twar e. Ref er to the memory maps in Chapter 2, Operating Instructions.

System Considerations
The MVME2603/2604 contains shared onboard DRAM (and, optionally, secondary cache memory) whose base address is software -selectable. Both the onboard processo r and offboard VMEb us devices see this local DRAM at base physical addre ss $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, listed in Appendix D, Related Documentation, for more
information. If the MVME2603/2604 t ries to access offboard reso urces in a none xistent
location and is not system controller, and if the system does not have a global bus timeout, the MVME2603/2604 waits forever for the VMEbus cycle to complete. This will cause the syste m to lock up. There is only one situation in which th e syste m might lack th is gl obal bus timeou t: when t he MVME2603/2604 is not the system controller and there is no global bus timeout el sewhere in th e system.
Multiple MVME2603/2604s may be insta lled in a single VME cha ssis. 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 to al low one MVME2603/2604 processor to broadcast a signal to any other MVME2603/2604 processors. All eight registers are accessible from any local processor as well as from the VMEbus.

The MVME2603/2604 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 the processor core voltage power i s s uppl ie d by the on-board +5V DC.

MVME2603/2604 VME Module

The MVME2603/2604 VME module furnishes +12V DC and (in MVME761 I/O mode) –12V DC power to the transition module through polyswitches (resettable fuses) R34 and R28 respectively. These voltage sources power the seri al po rt d river s and any LAN tra nsceiv ers connect ed to the transition module.

With the P2 adapter board cabled to a transition module and with an SCSI bus connected to the transition module, the green module illuminates when SCSI terminator power is available. If the LED on the transition module flickers during SCSI bus operation, check fuse F1 on the P2 adapter board.

System Considerations
9600 baud is the power-up default for serial ports on MVME2603/2604 boards. 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 bau d rate , some t ype of h ardwar e handsh aking — either XON/OFF or via the RTS/CTS line — is desirable if the system supports it.

Introduction

This chapter suppl ies infor mation for u se of the MVME2603/260 4 fami ly 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.

Applying Power

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 firmware initialization process is performed by the PowerPC PPCBug power-up or system reset. The firmware initializes the devices on the SBC module in preparation for booting the operating system.
2
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 following flowchart shows the basic initialization process that takes place during PowerPC system startup.
For further information on PPCBug, refer to Chapter 5, PPCBug; to

ABORT Switch (S1)

When activated by software, the ABORT switch can gene ra te an int errupt signal from the ba se board to the processor at a user-progra mmab le level. The interrupt is normally used to abort program execution and return control to the debugger firmware located in the MVME2603/2604 ROM and Flash memory. The int er rup t s ign al reaches the processor module vi a ISA bus interrupt line IRQ8 Z8536 CIO device, which handles various status signals, serial I/O lines, and counters.

Memory Maps

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 sectio ns give a general description of the MVME 2603/2604 memory organization from the above three points of view. Detailed memory maps can be found in the MVME2600 Series Single Board
Computer Programmer’s Referen ce Guide , list ed i n Appendix D, Re lated

Processor Memory Map

The processor memory map configuration is under the control of the Raven bridge control ler ASI C and the Fal con me mory c ont roll er chip 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.

Default Processor Memory Map
The default processor memory map that is valid at power-up or reset remains in effe ct until reprogra mmed for specific applications. Table 2-1 defines the entire default map ($00000000 to $FFFFFFFF). Table 2-2 further defines the map for the local I/O devices (accessible through the PCI/ISA I/O Space).

PCI Local Bus Memory Map

The PCI memory map is controlled by the Raven MPU/PCI bus bridge controller ASIC and by the Universe 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.

The VMEbus is programmable. Like ot her pa rts of the MVME260 3/2604 memory map, the mapping of local resources as viewed by VMEbus masters varies among applications.
The Universe PCI/VME bus bridge ASIC includes a user-programmable map decoder for the VMEbus-to-local-bus interface. The address translation ca pabi l it ies of the Univers e e nable 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 Series Single Board Computer Programmer’s Reference Guide, list ed in
Appendix D, Related Documentation. Figure 2-2 on page 2-9 shows the
overall mapping approach from the standpoint of a VMEbus master.

Endian Issues

The MVME2603/2604 supports both little-endian (for example, Windows NT) and big-endian (for exa mple, AIX) software . The PowerPC processor and the VMEbus ar e inherently bi g-endian, while the PCI bus is inherently little-endian. The following sections summarize how the MVME2603/2604 handles soft ware and hardware difference s i n big- and little-endian operati ons. For fu rther de tails o n endia n consider ations, refer to the MVME2600 Series Single Board Computer Programmer’s Reference Guide, listed in Appendix D, Related Documentation.
Processor/Memory Domain
The MPC603/604 processor can operate in both big-endian and little-endian mode. Howev er, it always tr eats the external processor/memory bus as big-endian by performing address rearrangement and reordering when running in little-endian mode. The MPC registers in the Raven MPU/PCI bus bridge con troller ASIC and the Falcon memory controller 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.
2
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.
http://www.motorola.com/computer/literature 2-15
Operating Instructions
2
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 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 ASIC
Because the PCI bus is li ttle-endian w hile the VME bus 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 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 Un iverse ASI C and th e addres s revers e-rea rranging effect of the Raven into account.

General Description

The MVME2603/2604 is a VME module singl e board computer eq uipped with a PowerPC Series micro processor. The MVME2603 is equi pped with a PowerPC 603 microprocessor; the MVME2604 has a PowerPC 604. 256KB L2 cache (level 2 secondary cache memory) is available as an option on all versions.
General Description
3
As shown in the Features section, The MVME2603/2604 offers many
standard features desirable in a computer system—such as synchronous and asynchronous seria l ports, parall el port, boot ROM and DRAM, SCSI, Ethernet, support for an external disk drive, and keyboard and mouse support—in a single-slot VME package. Its flexible mezzanine architecture allows relatively easy upgrades in memory and functionality.
A key feature of the MVME2603/2604 family is the PCI (Peripheral Component Interconnect) bus. In addition to the on-board local bus peripherals, the PCI bus supports an industry-standard mezzanine interface, IEEE P1386.1 PMC (PCI Mezzanine Card). PMC modules off er 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 I/O. There is also provision for additional expansion via a PMC carrier board.

SCSI Interface

The MVME2603/2604 VME module supports mass storage subsystems through the industry-standard SCSI bus. These subsystems may include hard and floppy dis k drives, streaming tape drives, and other ma ss storag e devices. The SCSI interf ace is i m ple ment ed us in g the Symbios 53C825A SCSI I/O controller at a clock speed of 40 MHz. The SCSI I/O controller connects directly to the PCI local bus.
The MVME2603/2604 routes its SCSI lines through the P2 connector to the MVME712M transition module (as il lus tr at ed in Figure 1-21 on page
1-47). The SCSI contro l line s ha ve fil ter n etworks to minimize th e effe cts
of VMEbus signal noise at P2. The SCSI bus is 16-bits wide in syst ems that support the VME64 extension
(that is, those e quippe d with 5-row, 160-pi n VME back plane connect ors) . The SCSI bus is 8-bits wide in VME systems that do not support the extension. Refer to the MVME712M User’s Manual, listed in Appendix D,
Related Documentation, for the pin assignments of the SCSI connectors
used on the transit ion module. Refer t o the Symbios 53C825A data man ual for detailed programming informati on, also listed in Appendix D, Related
Documentation.

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 MVME2603/2604 base board uses the sockets provided for SCSI bus terminators on the P2 adapter board used with the MVME712M. If the SCSI bus ends at the adapter board, termination resistors must be installed there. +5V DC power to the SCSI
TERMPWR signal and termination resistors is supplied through a fuse
bus located on the adapter board.
In MVME761 I/O mode, the P2 adapter board used with the MVME761 has a jumper to enable/d isable SCSI bus terminato r s. +5V DC power for SCSI termination is supplied through a polyswitch located on the adapter board.

Ethernet Interface

The MVME2603/2604 VME module uses Digital Equipment’s DECchip
3
21140 PCI Fast Ethernet LAN controller to implement an Ethernet interface that supports both AUI (via MVME712M) and 10BaseT/100BaseTX (via MVME761) connections. The balanced differential transceiver lines are coupled via on-board transformers.
The MVME2603/2604 routes its AUI and 10BaseT/100BaseTX lines through the P2 connector to th e transi ti on module (as illus trate d in Fig ure
1-21 on page 1-47 and Figure 1- 22 on page 1-49). The MVME712M f ront
panel has an industry-standard DB-15 connector for an AUI connection. The MVME761 supports 10BaseT/100BaseTX connections.
Every MVME2603/2604 is assigned an Ethernet station address. The address is $08003E2xxxxx, where xxxxx is the unique 5-nibble number assigned to the board ( tha t is , every board has a different value for xxxxx ).
Each MVME2603/2604 displays its Ethernet station address on a label attached to the base board in the PMC connector kee pout are a just beh ind the front panel. In addition, the six bytes including the Ethernet station address are stored in an SROM off the DECchip Ethernet controller, that is, the value 08003E2xxxxx is st ored in SROM. At an offset of $1F2C, the upper four bytes (08003 E2x) can be read. At an of fset of $ 1F30, the lowe r two bytes (xxxx) can be read. The MVME2603/2604 debugger, PPCBug, has the capability to retrieve or set the Ethernet station address via the CNFG command.
Note The unique Ethernet address is set at the factory and should not
be changed. Any attempt to change thi s address may cre ate node or bus contention and thereby render the board inoperable.
If the data in SROM 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 10BaseT/100BaseTX connector, refer to the user’s manual for the MVME712M or MVME761 (listed in Appendix D, Related
Documentation) respectively. Refer to the BBRAM/TOD Clock memory

PCI Mezzanine Interface

A key feature of the MVME2603/2604 family is the PCI (Peripheral Component Interconnect) bus. In addition to the on-board local bus devices (SCSI, Ethern et , gra phi cs, e tc . ), t he PCI bus supports an industry­standard mezzanine inter face, IEEE P1386.1 PMC (PCI Mezzan ine 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 MVME2603/2604 supports one PMC slot. Four 64-p in connectors on the base board (J11, J12, J13, an d J14) inter face with 32 -bit IEEE P1386 .1 PMC-compatible mezzanines to add any desirable function. The PCI Mezzanine Card slot has the following characteristics:
