MDR User Guide 79

SysPhysMemSize

Size of memory that VxWorks should handle. The current value used is

0x1b00000

for MDR systems and the user should not be change this item on its own initiative.

[MDC]

This section contains the information the BSP needs to know about the Midas DC (name

of the driver for the DE520 PMC board) installed on the MIDAS board.

PmcSlot

PMC slot where the Ethernet board is installed. Currently, this parameter is optional

and overrides the boot device <slot> number (for more information, see Chapter 3

MDR Host Software.

EthSpeed

Speed of the Ethernet network.

Values currently supported are:

10Mb 10 Mb/s standard Ethernet (default value)

100Mb 100 Mb/s fast Ethernet

AutoSense Auto-sense and switch to the correct speed

Note:

Some MDR-250 units may be shipped with an Ethernet PMC manufactured

by Osicom. At present, these PMCs do not correctly auto-sense the Ethernet

carrier speed, so the AutoSense option must not be used. EthSpeed must be

set to 10Mb or 100Mb as appropriate for the network to which the MDR will be

connected.

[VmeInterface]

This section contains information the BSP needs to know about the VME interface on

the MIDAS board.

VmeA32SlaveDisable

VME A32 slave image enabled flag. If this item is set to 1 (respectively 0) then the

VME A32 slave image is disabled (respectively enable). If this item is not set

correctly or missing then the default value is 0.

This parameter should be defined to 0 (or missing) when the network interface is

sm0

(SM Network requires a VME A32 slave image).

VmeA32SlaveBase

Base address of where the MIDAS DRAM should be mapped in VME A32. If this

item is missing then the VME A32 slave base address is computed by the BSP.

The default BSP computation puts the VME A32 slave base of a MIDAS acting as an

SM master (with a processor number of 0) at address 0x0.

For processor numbers different from 0, the following formula is used:

VmeBase = (ProcNum * 0x10000) + 0x4000000
