A
Base Address of Dynamic Memory 00000000 Beginning address of Dynamic
Memory (Parity and/or ECC
type memory). It must be a
multiple of the Dynamic
Memory board size, starting
with 0. Default is $0.
Size of Parity Memory 00100000 This is the size of the Parity type
dynamic RAM mezzanine, if
any. The default is the calculated
size of the Dynamic memory
mezzanine board.
Size of ECC Memory Board #0 00000000 This is the size of the first ECC
type memory mezzanine. The
default is the calculated size of
the memory mezzanine.
Size of ECC Memory Board #1 00000000 This is the size of the second
ECC type memory mezzanine.
The default is the calculated size
of the memory mezzanine.
Base Address of Static Memory FFE00000 This is the beginning address of
SRAM. The default for this
parameter is FFE00000 for the
onboard 512KB, or E1000000 for
the 2MB SRAM mezzanine. If
only 2 MB SRAM is present, it
defaults to address 00000000.
Sizeof Static Memory 00080000 This is the size of the SRAM type
memory present. The default is
the calculated size of the
onboard SRAM or an SRAM
type mezzanine.
ENV asks the following series of questions to set up the VMEbus interface for the MVME162 series
modules. You should have a working knowledge of the VMEchip2 as given in the MVME162 Embedded
Controller Programmer’s Reference Guide in order to perform this configuration. Also included in this
series are questions for setting ROM and Flash access time.
The slave address decoders are used to allow another VMEbus master to access a local resource of the
MVME162. There are two slave address decoders set. They are set up as follows:
Slave Enable #1 [Y/N] Y Yes, set up and enable the Slave
Address Decoder #1.
Slave Starting Address #1 00000000 Base address of the local
resource that is accessible by the
VMEbus. Default is the base of
local memory, $0.
