VMP1 Introduction

1. Introduction

The VMP1 is a comprehensive computing platform which brings togethor the latest advances in computing technology in a board designed for maximum performance, flexibility and versatility within a rugged compact format.

The design centered on realizing a board which addresses the need for increased computing capacity while at the same time reducing the size and number of system components in order to reduce space requirement s and optimize power dissipation.

The VMP1 is based on the MPC8240, a highly integrated microprocessor containing a PowerPC MPC603e core. This is the 250 MHz version with a Floating Point Unit (FPU). One of the prime advantages of utilizing the established and proven MPC603e core is the associated broad infrastructure of support that has built up around it . All of the noteworthy third-party software tool vendors provide tools for the MPC8240.

An important feature of the board is the integration of a PCI bus within a VME-CPU board. This connects the MPC8240 with the Fast Ethernet controller and the Tundra Universe II PCI/VME bridge and also to the onboard 100-pin PCI expansion connector, enabling the connection of the full range of PCI peripherals.

The VMP1 employs an OS-independent boot loader that enables the loading of any operating system. This boot loader makes an update of the Flash content s and automatically downloads from Flash to SDRAM before booting the OS. For performance reasons the OS is started from the SDRAM.

The power of the board is greatly enhanced by means of the PCI expansion connector which makes it possible to cascade one or two additional IO1 modules onto the board resulting in a total package of either 8HP or 12HP. Both IO1 modules may be used to carry PMC modules. Given the wide range of PMC modules now available, this feature affords the user a very wide range of options. Additionally, one can substitute a module designed to provide an even greater range of PCI peripherals in place of either of the IO1 modules. These features enable, for example, the connection of the widest range of system I/O components such as various field busses, Fast Ethernet and Ultra 2 SCSI, to name just a few . The complete range of expansion possibilities is thus mad e available to the user by the VMP1.

VMP1 Introduction

1.2 Board Overview

The VMP1 is a 3U VME CPU board featuring a powerful CPU (number cruncher). The design is based on the new highly integrated Motorola PowerPC processor MPC8240, which integrates a PCI interface and several peripherals inside one Chip.

Two standard memory configurations (32 MB or 64 MB SDRAM) are available, with 128 MB available on request. Flash memory for integrating the initial bootloader and ROMable operating systems are provided . Additionally, NV SRAM or a Disk-On-Chip (by M-Systems) can be placed on a DIL socket for special purposes.

The board controls the VMEbus through the Tundra UNIVERSE II PCI-VME bridge which is an industrial standard for connecting the PCI bus to the VME. Improved VMEbus master and VMEbus slave performance with an increase of FIFO depth and optimized DMA transfer are some of the outstanding features of this device.

The VMP1 is also able to communicate with the environment through a Fast Ethernet interface and two serial interfaces at the front side of the board. One of the serial interfaces is a RS232 full modem interface while the other is a software-configurable RS232/RS485 port. These UARTS support baud rates up to 1.5 Mbps and are software compatible with the 16550 UART from National Semiconductor. They contain 128 Byte Transmit FIFO and 128 Byte Receive FIFO for reducing the bandwidth requirement of the CPU.

The Ethernet is realized with the Intel 82559 with full duplex support at both 10/100 Mbps possible. This Fast Ethernet controller with an integrated 10/100 Mbps physical layer device is the foremost solution for PCI board LAN designs. It combines low power consumption with a small package design which is ideal for power and space constrained environments.

Anticipating the VMP1's use in data critical applications, the memory data path contains a selectable in-line ECC controller which can provide SDRAM single-bit error correct or double-bit error detect.

For mass data transmission a dual channel DMA controller is provided. It can be programmed directly or through the use of descriptor chains located in memory. Data can thus be moved from PCI to memory or vice versa, memory to memory, or PCI to PCI.

The MPC8240 supports processor control and visibility through the JTAG/COP (common on-chip processor) interface that is available on the VMP1. Utilizing third party tools, the developer can access and control the processor. It also has standard IEEE

1149.1a-1993 compliant boundary scan capability. The ECC data path has a mechanism to manually inject errors into memory for use with maintenance and diagnostic utilities. Furthermore a watch point and capture register on the internal bus and a set of address attributes on the external memory and PCI buses facilitate debugging analysis.

VME interface

In addition to the standard functionality required by a VME CPU, the VMEbus interface (Tundra Universe 2) provides:

• automatic First-Slot detection

• integral FIFO buffers for multiple transactions in both directions

• programmable DMA controller with linked list support.

• Mailbox

VMP1 Installation

3. Installation

The VMP1 has been designed for easy installation. However, the following importantstandard precautions must be observed. Some other important information is also set out below.

3.1 Board Installation

Slot Selection

The VMP1 is designed so that it may be used in any free slot of a 3U VME Backplane. It has an automatic first slot detection mechanism which configures it as a System Controller when placed in the far left slot.

When configured as the System Controller, it enables its system clock and arbiter in order to control the entire VME bus.

Default setting of the serial Interfaces: 9600 Baud, 8N1 On initial startup a message of greeting comes up. When the VMP1 is invoked for the first time, a Bootstrap loader startup messag e comes

up on the “term” serial port, which will provide you with some configuration information on the system and a command prompt for entering bootstrap loader commands. For a detailed description of these commands please see chapter 5 Bootstrap loader.

Caution!

Please switch off the VME system before installing the board in a free slot. Failure to do so could endanger your life/health and may damage your board or system.

Note:



Certain VME boards require bus master capability. If you are in doubt whether such features are required for the board you intend to install, please check your specific board and/or system documentation to make sure your system is provided with an appropriate free slot to insert the board.

ID 26037, Rev. 01 Page 3 - 3® 2002 PEP Modular Computers GmbH

VMP1 Installation

ESD Equipment!

Your VMP1 board contains electrostatically sensitive devices. Please observe the necessary precautions to avoid damage to your board:

• Discharge your clothing before touching the assembly. Tools must be discharged before use.

• Do not touch components, connector-pins or traces.

• If working at an anti-static workbench with professional discharging equipment, please do not omit to use it.

PEP Advantage

The VMP1 is designed to be bootstrapped from the Flash device alone.

3.1.1 Front Panel I/O Connectors

Attention!

Due care should be exercised when connecting cabling in order to avoid damage to your connected device and/or the VMP1 board.

For pinouts of the Front Panel connectors, please see Chapter 2: Functional Description, sections 2.4.3.2 and 2.4.3.3

4. Configuration

4.1 Jumper Settings

Please see Figures 2-3 and 2-4 in Chapter 2 to view the positions of the jumpers and resistors on the board.

4.1.1 Bootstrap Loader / Socket Jumper J1

The Jumper J1 is used to select the memory position from which the VMP1 fetches its boot code. It determines the address position of the onboard Flash window and the Flash/SRAM expansion socket (DIL600, 32-pin).

Table 4-1: Bootstrap Loader / Socket Jumper J1 Settings

Note: All resistors are 0 ohms

4.1.4 RS485 Termination (Onboard Interface Only)

When the VMP1 is using the onboard RS485 interface and is the last on the RS485 bus, then the RS485 interface must provide termination resistance. The purpose of J3 is to enable this line termination resistor (130 R).

Table 4-3: Jumper Settings for RS485 Termination

Termination J3

ON Set OFF Open

Additionally, the correct idle line potential must be provided at one location within the RS485 bus. J4 and J5 are used for this purpose. Pullup/Pulldown resistors are 380 Ohm each.

Note:



Ensure that the reference potential for the RS485 signals are set in one location only on the bus.

The NetBootLoader it self is a software utility which initializes the CPU board for operation before turning control over to either an application or to an operator. This software also provides the capability to monitor and control the operation of the NetBootLoader itself, 01display system status information, to program execut able code and dat a to the Flash memory, and to load and start application software.

To attain full operational capability, the NetBootLoader FLASH must be programmed by the user with application software. Once the application has been programmed to Flash memory, the NetBootLoader will support the complete boot operation. The following chapters describe the functioning of the NetBootLoader and how to program the Flash memory.

5.1 General Operation

Upon power on or a system reset, the NetBootLoader is started. The CPU board is configured for operation and control is either passed to an application or an operator. In the event a valid application has been programmed into the Flash memory and no operator intervention takes place, the application is copied from FLASH into SDRAM and control is p assed to the application. If the NetBootLoader does not find a valid application or operator intervention has occurred, control is passed to the operator . The operator now has control to determine the system status, make configuration changes, read or program the Flash memory, or to restart or shut down the system.

The operator command interfacing with the NetBootLoader is accomplished either via the TERM serial port or the Ethernet port. During the boot operation a command interpreter is st arted which allows the operator to input commands to the NetBootLoader. Prior to interfacing via the Ethernet port the network must be configured. This is done via the TERM port.

5.2 NetBootLoader Interfaces

There are four possibilities to interface with the NetBootLoader:

• Via the ABT (Abort) switch

• Via the TERM serial interface

• Via the SER0 serial interface

• Via the Ethernet interface

Gaining access to the NetBootLoader is a function of the contents of the Flash memory and the “BootWaitT ime ” setting. If there is no valid application progra mmed into the Flash memory, the boot operation automatically terminates after the CPU board has been initialized and control is passed to the command interpreter. If there is a valid application in the Flash memory the boot operation is delayed according to the setting of the boot wait time. The green user LED (U) on the front panel flashes indicating that the boot operation is in a wait state. During this time the operator may intervene in the boot operation either by pressing the ABT (Abort) switch, entering the “abort” command via the TERM interface, or by performing a su ccessful telnet login via the Ethernet interface. If the operator does not intervene, the boot operation is continued after the boot wait time has been exceeded.

NetBootLoader VMP1

5.2.1 ABT (Abort) Switch

The ABT switch, located on the CPU board front panel, provides the operato r with the ability to directly terminate the boot operation during the boot wait time which is indicated by the “U” LED blinking. This is the sole purpose of the ABT switch during the NetBootLoader operation.

5.2.2 TERM Serial Interface

The TERM serial port is used to provide direct operator interfacing to the NetBootLoader. As soon as the CPU board has been initialized this port is activated and the operator may input commands. During the boot wait time the operator may terminate the boot operation and take control of the NetBootLoader. Once the boot wait time is exceeded the command interpreter is deactivated and the operator no longer has access to the NetBootLoader.

The TERM serial interface may either be directly connected to a terminal device or may interface with a terminal emulator.

5.2.3 SER0 Serial Interface

The SER0 serial port is used to provide the NetBootLoader with the ability to access Motorola S-Records for programming an application to FLASH. No command interpreter is available for this interface.

5.2.4 Ethernet Interface

The Ethernet interface provides the capability of remotely interfacing with the NetBootLoader. Prior to using this interface it is necessary to configure the NetBootLoader network settings. This is accomplished via the TERM interface. Once the network settings have been made, the remote operator has the same capabilities as with the TERM interface. During the boot wait time the operator gains control of the NetBootLoader by logging into it via the Ethernet interface. This causes the boot operation to be terminated and gives control to the remote operator.

The Ethernet interface uses the telnet protocol for operator interfacing with the NetBootLoader. In addition to the operator interface via Ethernet, the NetBootLoader also uses the Ethernet interface for ftp server access.

5.3 NetBootLoader Functions

In addition to initializing the CPU board for operation and the loading and starting of applications, the NetBootLoader provides the following operator monitor and control functions:

• NetBootLoader control

• system status monitoring

• ftp server access

• FLASH reading and programming operations

• Motorola S-Record acquisition

These functions are described in detail in the following chapters.

5.4 Operating the NetBootLoader

5.4.1 Initial Setup

The CPU board is delivered with the NetBootLoader already installed in the onboard soldered FLASH and is ready for operation. However , in order for the CPU board to be used in a system, application software must be made available for use. This is accomplished by programming the application also to the onboard soldered Flash memory where the NetBootLoader is located.

Upon initial power up the NetBootLoader is started automatically. As soon as the NetBootLoader has completed initialization of the CPU board, it checks to see if there is a valid application programmed in FLASH and at the same time initiates a command interpreter which the operator can access either via the TERM or telnet interfaces. If there is no valid ap plication in memory, the NetBootLoader terminates the boot operation, and waits for operator intervention. As this is the case when the CPU board is first powered up, the operator now ha s t he o pportun ity to program an application.

Prior to programming an application it may be necessary to configure the NetBootLoader or perform other functions depending on the user’s application development environment or application requirements. Once this has be accomplished and the application has been programmed, the CPU board is ready for operation.

The following chapters provide information on how to set up and operate the NetBootLoader itself, initiation of the telnet interface, and how to program an application to FLASH.

5.4.2 Accessing the NetBootLoader

Initial access to the NetBootLoader can only be achieved via the TERM interface. Prior to using the telnet interface, the Ethernet parameters must be set and this can only be accomplished initially via the TERM interface. Once valid Ethernet parameters and the telnet log in password have be set, the telnet interface is available for operation.

Use of the TERM interface requires either a terminal or a terminal emulator. Use of the telnet interface requires a remote telnet login to the NetBootLoader.

Availability of the command interpreter depends on the system st atus. If there is no valid application programmed, the command interpreter is available as long as the operator requires it. If a valid application is programmed, the command interpreter is only available for the duration of the boot wait time. If the operator requires the command interpreter for a longer time he must terminate the boot operation before the boot wait time is exceeded.

Upon initiation of the command interpreter, a prompt is sent to the TERM interface and commands may be entered. To gain access to the NetBootLoader from a remote location via Ethernet a telnet login must be performed. If the boot wait time has not been exceeded, a telnet login automatically terminates the boot operation and a command prompt is sent to the telnet remote interface.

Once the operator has control of the NetBootLoader, he may perform any required action. To continue with the operation of the CPU board, the system must either be cold started or the operator must issue a “reset” command. In either event, the NetBootLoader is restarted and the boot operation begins anew.

NetBootLoader VMP1

5.4.3 NetBootLoader Configuration

There are several NetBootLoader commands which provide the operator with the capability to configure specific parameters which are used by the NetBootLoader for interfacing operations. These commands are:

• BW (BootWait)

•NET

• PASSWD

• PF (Port Format)

Default settings are available for all the above commands except for “net” which is dependent on the application environment.

5.4.3.1 BW

This command is used to display or set the actual boot wait time used by the NetBootLoader to delay the boot operation before proceeding with the loading and starting of an application. If this time is set too short it may only be possible to gain access to the NetBootLoader via the “ABT” switch.

The BootWaitTime value is stored in the boot section of the serial EEPROM. This section is validated with a CRC code to avoid the setting of random parameters.

Note ...

If the CRC of the boot section is not valid, changing the BootWaitTime will have no effect because the “bw” command does not validate an invalid CRC. In this case, a default timing of 5 seconds is always used.

To validate an invalid CRC, an operating system utility must be used, or, alternatively, the “-f” option of the “bw” command must be issued.

Warning !!!

Using the “bw -f” command to validate invalid entries may adversely impact the operation of the operating system.

5.4.3.2 NET

This command is used to set or display the parameters for the configuration of the Ethernet interface of the CPU board. The Ethernet interface is only available after these settings have been made. Once these settings have been made, the system must be cold started or reset for them to take effect.

5.4.3.3 PASSWD

This command is used to set the password used by the NetBo otLoader for the operation of the telnet interface. No password is required for access from the TERM interface.

VMP1 NetBootLoader

5.4.3.4 PF

This command is used to set the port parameters for the TERM a nd SER0 serial interfaces only for the current operator session. The next system restart will cause these settings to revert to the default settings of: 9600 Baud, 8 bits per character, 1 stop bit, and no parity. This is done to preclude a system lockout when restarting due to incompatible settings.

5.4.4 telnet Login

A telnet login to the NetBootLoader is only possible during the boot wait time and only af ter the Ethernet network parameters have been set.

T o ef fect a telnet login the operator performs the standard telnet log in procedure during the boot wait time. The NetBootLoader responds by suspending the boot wait and requests a login password. The operator then enters a password. If the password is valid, the boot wait is terminated and the operator can now access the NetBootLoader. If the password is invalid, the telnet login procedure is terminated and the boot operation continues.

In the case of an invalid password, the login procedure may be repeated as often as required within the boot wait time. Once the boot wait time is exceeded, a telnet login is no longer possible.

5.4.5 FLASH Operations

To achieve an operable system for an application, the application software must be programmed to FLASH. The NetBootLoader supports the programming of the application to FLASH. In addition to this, it also supports the updating of the NetBootLoader itself as well as data transfer from the FLASH to the data buffer and from the data buffer to an ftp server. The following chapters provide information on performing the various types of FLASH operations.

5.4.5.1 FLASH Offsets

All FLASH is treated as one uniform FLASH, regardless of the physical addresses of the devices involved. If a DIL FLASH is plugged in the Memory Expansion socket, it is added to the FLASH area as well. All offsets are based from the beginning of the FLASH area. This means that 0x0 is the beginning of the first FLASH bank. The NetBootLoader itself is located at the beginning of the FLASH area and for this reason this area cannot be used for application image programming. To display an overview of the current FLASH organization use the “info” command.

If the application image is an operating system (which is the default case), it must be programmed without an offset. When such an image is programmed to FLASH, the image length and CRC information is also programmed along with the image to FLASH. This information is used by the NetBootLoader to determine the validity of the image during the boot operation. During system startup, a valid image is copied to SDRAM address 0x0 and started at offset 0x100 after the boot wait time is exceeded.

If an offset is specified, the image will be programmed exactly at this offset without adding length or CRC information. This option is intended for the storing of configuration information which is required to be located in FLASH.

NetBootLoader VMP1

5.4.5.2 Programming an Application

The application image itself must be compiled and linked to run from the SDRAM base a ddress 0x0 of the CPU. The image must contain executable PPC code at offset 0x100 which is the usual case with ROM/Flash images.

Gaining access to the image for programming to FLASH depends on where it is located. The NetBootLoader can access three different sources for images:

• ftp server

• Motorola S-Records

• memory within the visible address range of the CPU board

The NetBootLoader uses a single data buffer for downloading an image from an ftp server or an image as Motorola S-Records. These images must first be downloaded to the data buffer prior to being programmed to FLASH. An image located within the visible address range of the CPU board is directly accessible for programming.

To access an image located on an ftp server, the “get” comman d is used. To perform Motorola S-Record acquisition, the “sl” (SLoad) command is used. Once the image is in the data buffer, the FLASH is programmed using the “lf” (Load Flash) command. For an image within visible memory, the “lf” (LoadFlash) command is used to program directly to FLASH.

5.4.5.3 ftp Server Access

To gain access to an application image file stored on an ftp server the Ethernet interface is used. Images are downloaded to the data buffer using the f tp protocol. To use this interface the Ethernet parameters must first be set and then the system must be rest a rted. During boot wait the operator must gain control of the NetBootLoader and perform an ftp server login. After a successful login, the operator then locates the image file required and downloads it to the dat a buffer. As with any type of server session, the operator should logout when the session is finished.

Note ...

The commands “get” and “ls” use the same data buffer. Therefore if an “ls” command is issued after a “get” command the dat a buffer will be overwritten. If an “lf” command follows the “ls” the NetBootLoader refuses to program the overwritten data buffer to the FLASH.

5.4.5.4 Motorola S-Records

The NetBootLoader will also accept Motorola S-Records as an application image. The “sl”’ command accepts S1, S2 and S3 records. Operation is terminated by the appropriate S9, S8 or S7 record. Other types of records are ignored.

The checksum of every record except end records is checked. Bad records are rejected by the NetBootLoader. The address range of every record is also checked. Records which fall outside of the internal buffer are rejected.

The records must be 0-based. This means that it’s address must correspond to the address where they will be loaded in the data buffer relative to its start. If necessary, the base address can be modified with the -o option of the “sl” command.

VMP1 NetBootLoader

Note ...

If the data buffer is programmed to FLASH without the -o option (program a startable image) the downloaded image is copied to RAM during startup and is executed there. For this reason application images which require to be programmed must start at the address 0x0.

The image must start at the absolute address 0x0 and must contain executable PPC code at the absolute address 0x100. If S1 or S2 record input is preferred, please note that these records only include 16 and 24-bit wide addresses. If no switch to another record type is included it must be ensured that the code is not larger than the address range covered.

Note ...

Neither the “sl” nor “If” command can be used to program Motorola S-Records to RAM areas.

For accessing the Motorola S-Records, both the TERM and SER0 interfaces can be used. The user LED (“U”) flashes slowly while downloading indicating that the transfe r is in progress. The transfer itself may take several minutes to complete.

Ensure that the XON/XOFF protocol is used on the host side. This is a fixed setting and cannot be changed. Additionally, ensure that the host does not stop transmission after a number of lines (e.g. OS-9: use the ‘nopause’ attribute).

The TERM and SER0 serial interface parameters can be modified with the “pf” command.

5.4.6 Updating the NetBootLoader

In addition to programming an application to FLASH, the NetBootLoader it self can be up dated. The new version of the image can be made available in one of two ways:

• Via an ftp server

• Via a DIL FLASH device

5.4.6.1 Updating With an Image Loaded Via an ftp Server

The image is downloaded in the same way as an application image (refer to chapter 5.4.5.3). The new version of NetBootLoader image is then programmed using the “clone -n” command.

5.4.6.2 Updating Via a Separate DIL FLASH

The new version of the NetBootLoader image must be programmed to a separate DIL FLASH device (e.g. AM29F040) with an external programmer and then plugged on the Memory Exp ansion socket of the CPU board. The NetBootLoader must be started and operator must gain control of the NetBootLoader. Either the current NetBootLoader (Boot Jumper removed) or the new NetBootLoader version (BootJumper inserted) may be used for this operation.

The “clone” command is then used to program the new NetBootLoader version to FLASH. If for some reason the NetBootLoader programmed in the soldered FLASH has been improp-

erly modified (e.g. by a program which accidentally erases or overwrites the chips), this is the only method to reprogram the onboard soldered FLASH. In this case, the boot operation must be started with the Boot Jumper inserted (boot from DIL FLASH).

NetBootLoader VMP1

5.4.7 Uploading a FLASH Area

The NetBootLoader also has the possibility to upload certain areas of the FLASH to a host using the Ethernet interface. To use this interface the Ethernet parameters must first be set and then the system must be restarted. During boot wait the opera tor must gain control of the NetBootLoader and perform an ftp server login. After a successful login, the operator then stores the FLASH area to be uploaded to the local data buf fer using the “sf” command. Using the “put” command transfers the contents of the data buffer to the ftp server. As with any type of server session, the operator should logout when the session is finished.

5.5 Plug and Play

On the CPU board the NetBootLoader includes “Plug and Play” functionality. This ensures that the board is completely initialized and that all resources necessary for PCI devices (addresses, interrupts etc.) are assigned automatically. This important feature has the advantage that conflicts do not arise when PCI devices are added or removed. Furthermore, the operating system itself does not include the board initialization code.

5.6 Porting an Operating System to the CPU Board

The image for the absolute address 0x0 should be linked with an entry point at the absolute address 0x100.

One should not attempt to reassign the PCI BAR registers. The assigned values should be read back and these should always be used in the drivers.

The “interrupt line” field in the PCI configuration header is initialized with the IRQ line number to which the INTA of the device is routed.

It is not necessary to rewrite the “EUMBBAR” field in the KAHLUA (MPC 8240) configuration space as this has already been done by the NetBootLoader. The existing value should be used.

Downloaded images are never executed from the FLASH due to the fact that on the CPU board it is paged. The programmed image is always downloaded to SDRAM, the absolute address 0x0 being downloaded first. There is no configuration option available to amend this process. If it is necessary to relocate the image to another address after download, simply add a small assembly routine at the beginning of the code which will move the image to the correct address.

-k option: keep retain surrounding contents

-m option: memory (address)

<adr> parameter: value: hexadecimal

absolute address of image to be programmed

-l option: length

<len> parameter: value: hexadecimal

length of image to be programmed

DESCRIPTION: Without parameters, the FLASH is programmed using the contents of

the data buffer. If no image is available in the data buf fer, the FLASH programming is terminated.

NetBootLoader VMP1

DESCRIPTION: If no offset option (“-o”) is specified the image is considered to be

valid and is therefore added along with CRC and length information. If the CRC is determined to be valid during the next startup, the

image is copied to the absolute address 0x0 and started at 0x100 after the boot wait time has been exceeded.

Normally, the local data buffer holds the image to be programmed. However, if the “-m” and “-l” parameters are specified, the image is programmed from the absolute address specified.

If “<offset>” is specified, the contents are programmed exactly at this offset in FLASH. No length and no CRC information is added.

The “-k” option can be specified to prevent deletion of the surrounding FLASH contents.

FLASH memory can only be erased sector-wise. If an image is programmed to a certain offset with the “-o” option, at least this sector (and maybe one or more of the following sectors depending on the size of the image) will be erased. The “-k” option can be used to retain the surrounding data, however, this slows down the operation significantly.

To achieve fast programming of parameter images without destroying other FLASH contents, the data should be placed at a sector boundary and the sector(s) must not contain any ot her data or executable images. If organized this way, use of the “-k” option can be avoided.

Note: The “lf” command cannot be used to program the NetBootLoader.

IP address of CPU board: nnn.nnn.nnn.nnn

-netmask option: netmask

<netmask> parameter: value: numerical string

netmask of CPU board: nnn.nnn.nnn.nnn

-gw option: gateway

<gateway> parameter: value: numerical string

gateway address for network: nnn.nnn.nnn.nnn

-f option: force CRC update

DESCRIPTION: To set or display the parameters of the Ethernet interface the

command “net” is used. Initially the CPU board does not have a valid Ethernet interface

configuration, and, therefore, this interface is inoperable. The initial configuration must be done from the TERM interface using the command “net ... -f”.

Using the “-f” option forces a CRC to be performed and stored along with the other configuration parameters in the serial EEPROM.

Once the initialization of the Ethernet interface is done, the CPU board must be restarted for the parameters to take effect. Later changes to the parameters do not require the use of the “-f” option to force a CRC. This is done automatically. Only in the event that the Ethernet interface does not properly initialize, may it be necessary to re-enter the parameters using the “-f” option.

NetBootLoader VMP1

PASSWD

FUNCTION: Set the telnet password

SYNTAX:

DESCRIPTION: To set the password for telnet sessions with the NetBootLoader the

passwd [-f | -d]

where:

passwd command

-f option: if password is not known

-d option: disable disable telnet login (remote access)

command “passwd” is used. This command is interactive, meaning that after it is issued, the NetBootLoader responds with an appropriate request to the operator which must be properly acknowledged or the operation fails (refer to USAGE below).

To set the password in the event it is unknown, use the option “-f”. This is can only be accomplished from the TERM interface and not from the Ethernet interface.

With the option “-d”, the remote telnet login can be disabled by invalidating the password.

USAGE: Set password

COMMAND / RESPONSE:

NetBtLd> passwd Old Password: ***** New Password: ***** Type again : ***** NetBtLd>

(The old password must be known)

Set password when the old password is not known COMMAND / RESPONSE:

NetBtLd> passwd New Password: ***** Type again : ***** NetBtLd>

terfaces the command “pf” is used. At startup the settings for the “TERM” and “SER0” interfaces are al-

ways set to the default values (9600/8/n/1). This is to avoid a possible system lockout. If other settings are required during operation of the NetBootLoader they may be made. If changes are made, it must be ensured that corresponding parameters are used for th e operator consle.

Issuing this command without parameters being spe cif ied will display the current serial port settings.

Syntax-wise, no spaces are permitted between the parameters and they must be separated with a slash. Not all parameters must be specified, but the “/” characters must be present to distinguish the different parameters from each other. The sequence can be aborted after every option.

VMP1 VMP1-IO1 Module (Optional)

VMP1-IO1 Module (Optional)

A Overview

The PEP VMP1-IO1 module has been designed to provide the VMP1 user with an ef fective gateway to the world of PMC modules. This additional capability opens up the broadest range of expansion possibilities.

PMC modules are renowned for their flexibility and versatility of use. They afford the user wide ranging system-independent solutions by means of easily interchanged or upgraded mezzanine add-on modules. The PEP VMP1-IO1 has been designed to maximize the advantages provided by PMC modules in a 3U environment.

A special feature of the VMP1 is the ability to cascade two of one another. This means that the VMP1 is able to carry any two mendous advantages in terms of expandability and flexibility are thus made available to the user as a result of the addition of this cap ab ility to th e board’s many outstanding features.

The VMP1-IO1 is a 3U non-intelligent, passive CPCI carrier board with one PMC slot.

Some of the Outstanding Features of the VMP1-IO1

• 32 Bit / 33MHz PCI Bus on the PMC side

• it supports the Interrupts INTA, INTB, INTC and INTD

• i t supports all the signals of the PCI Bus on its connectors Jn1 (CON2), Jn2 (CON3)

• The connectors which connect the mezzanine board with the carrier include all the signals of a 33MHz, 32-bit, multi-master PCI bus, the power rails for 5V, 3.3V, V(I/O) and other specialised signals for Board Detection.

Features of the PEP Modular Computers’ PMC modules

PEP Modular Computers’ PMC modules are operable in both CompactPCI and VME systems. They offer all the key benefits of PC I/O technology, namely:

• low cost solutions

• high performance

• a processor independent local I/O bus

• a broad range of I/O peripheral devices

of these IO1 modules on top

PMC modules. Tre-

PEP Modular Computers’ PMC modules may be installed on a variety o f dif fere nt carrier boards, including:

• CompactPCI 3U/6U: CPU CP302, CP600, CP602, CP610, CP611, CP612

• CompactPCI PMC carrier boards such as the CP390 and CP690

B Board Interfaces

PCI Expansion Connector

The PCI expansion connectors CON2/CON3 provides all the necessary signals for data transfer as defined by PCI Specification Rev. 2.1.

PMC Interface

The PMC interface provides an easy way to extend the VMP1 via the wide array of interfaces and functions which are available on PMC modules produced by the entire range of PMC vendors. PMC connectors provide a 32-bit wide PCI data path with a speed of up to 33MHz which is routed to the onboard connectors Jn1 and Jn2. These connectors also provide the power supply for the PMC module. The interface has been designed to comply with the IEEE 1386.1 specification which defines a PCI electrical interface for the CMC (Common Mezzanine Card) form factor.

Power Supply

The onboard DC/DC converter of the VMP1-IO1 also produces 3.3V supply voltage from the 5V provided on the VME backplane. This is necessary in order to create compatibility with the PMC modules whose power consumption is in excess of what the baseboard (VMP1-IO1) can provide.
