GEMVME6100 Single-Board Computer Programmer’s Reference Guide

Safety Summary

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

could result in personal injury or damage to the equipment.

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. If the

equipment is supplied with a three-conductor AC power cable, the power cable must be plugged into an approved

three-contact electrical outlet, with the grounding wire (green/yellow) reliably connected to an electrical ground

(safety ground) at the power outlet. The power jack and mating plug of the power cable meet International

Electrotechnical Commission (IEC) safety standards and local electrical regulatory codes.

Do Not Operate in an Explosive Atmosphere.

Do not operate the equipment in any explosive atmosphere such as in the presence of flammable gases or fumes.

Operation of any electrical equipment in such an environment could result in an explosion and cause injury or

damage.

Keep Away From Live Circuits Inside the Equipment.

Operating personnel must not remove equipment covers. Only Factory Authorized Service Personnel or other

qualified service personnel may remove equipment covers for internal subassembly or component replacement

or any internal adjustment. Service personnel should not replace components with power cable connected. Under

certain conditions, dangerous voltages may exist even with the power cable removed. To avoid injuries, such

personnel should always disconnect power and discharge circuits before touching components.

Use Caution When Exposing or Handling a CRT.

Breakage of a Cathode-Ray Tube (CRT) causes a high-velocity scattering of glass fragments (implosion). To

prevent CRT implosion, do not handle the CRT and avoid rough handling or jarring of the equipment. Handling

of a CRT should be done only by qualified service personnel using approved safety mask and gloves.

Do Not Substitute Parts or Modify Equipment.

Do not install substitute parts or perform any unauthorized modification of the equipment. Contact your local

Motorola representative for service and repair to ensure that all safety features are maintained.

Observe Warnings in Manual.

Warnings, such as the example below, precede potentially dangerous procedures throughout this manual.

Instructions contained in the warnings must be followed. You should also employ all other safety precautions

which you deem necessary for the operation of the equipment in your operating environment.

Introduction

This chapter briefly describes the board level hardware features of the 

MVME6100 single-board computer, including a table of features and a 

block diagram. The remainder of the chapter provides memory map 

information including a default memory map, MOTLoad’s processor 

memory map, a default PCI memory map, MOTLoad’s PCI memory map, 

a PCI I/O memory map, and system I/O memory maps.

Note Programmable registers in the MV64360 system controller are 

documented in a separate publication and obtainable from 

Motorola Computer Group by contacting your Field Area 

Engineer. Refer to Appendix A, Related Documentation, for 

more information on obtaining this documentation.

Overview

The MVME6100 is a single-board computer based on the PowerPC 

MPC7457 processor, the Marvell MV64360 system controller, up to 2 GB 

of ECC-protected DDR DRAM, up to 128MB of Flash memory, a dual 

Gigabit Ethernet interface, two asynchronous serial ports, and two 

IEEE1386.1 PCI, PCI-X capable mezzanine card slots (PMCs

Memory Maps

Default Processor Memory Map

The MV64360 presents a default CPU memory map following RESET 

negation. The following table shows the default memory map from the 

point of view of the processor. Address bits [35:32] are only relevant for 

the MPC7457 extended address mode and are not shown in the following 

tables. (Note that it is the same as the GT-64260A with the addition of 

integrated SRAM.)

ABORT_L

Abort. This bit reflects the current state of the onboard abort signal. 

This is a debounced version of the abort switch and may be used to 

determine the state of the abort switch. A set condition indicates that 

the abort switch is not depressed while a cleared condition would 

indicate that the abort switch is asserted.

FLASH_BSY_L

FLASH Busy. This bit provides the current state of the Flash Bank A 

StrataFlash device Status pins. These two open drain output pins are 

wire ORed. Refer to the appropriate Intel StrataFlash data sheet for a 

description on the function of the Status pin.

FUSE_STAT

Fuse Status. This bit indicates the status of the onboard fuses. A 

cleared condition indicates that one of the fuses is open. A set 

condition indicates that all fuses are functional.

SROM_INIT

SROM Init. This bit indicates the status of the SROM Init. A cleared 

condition indicates that the SROM Init is disabled. A set condition 

indicates that the SROM Init is enabled and the MV64360 was 

initialized using the MV64360 User Defined Initialization SROM at 

$A6.

TSTAT_MASK

Thermostat Mask. This bit is used to mask the DS1621 temperature 

sensor thermostat output. If this bit is cleared, the thermostat output 

will be enabled to generate an interrupt on GPP3. If the bit is set, the 

thermostat output is disabled from generating an interrupt.

FBOOTB_WP

Software Flash Bank B Boot Block Write Protect. This bit is to provide 

software-controlled protection against inadvertent writes to the Flash 

Bank B Top 1 MB (0xFFF00000) space. Clearing this bit and disabling 

HW write-protect will enable writes to the Bank B Flash Top 1MB 

boot block devices. This bit is set during reset and must be reset by the 

system software to enable writing of the Flash Bank B boot block.

FBA_WP_HDR

Hardware Flash Bank A write protect header status. Read ONLY. 

Hardware jumper configuration can not be overridden by the software 

control bit 6 in this register. 

FBOOTB_WP_HDR

Hardware Flash Bank B Boot Block write protect header status. Read 

ONLY. Hardware jumper configuration can not be overridden by the 

software control bit 3 in this register. 

IPMC_PRSNT

IPMC Module Present. If set (HIGH true), there is PMCspan module 

installed. If cleared, the PMCspan module is not installed.

EREADY1

EREADY1. Indicates that the PrPMC module installed in PMC slot 2 

is ready for enumeration when set. If cleared, the PrPMC module is not 

ready for enumeration. The PrPMC software must assert EREADY# 

for this bit to be set. The purpose of EREADY# is to provide a 

signaling method indicating that a non-monarch (vassal) PrPMC is 

ready to be enumerated.

EREADY0

EREADY0. Indicates that the PrPMC module installed in PMC slot 1 

is ready for enumeration when set. If cleared, the PrPMC module is not 

ready for enumeration. The purpose of EREADY# is to provide a 

signaling method indicating that a non-monarch (vassal) PrPMC is 

ready to be enumerated.
