Memory Configuration Defaults:
The default configuration for Dynamic RAM mezzanine boards will position the
mezzanine with the largest memory size to start at the address selected with the ENV
parameter ‘‘Base Address of Dynamic Memory’’. The Base Address parameter defaults
to 0. The smaller sized mezzanine will follow immediately above the larger in the
memory map. If mezzanines of the same size and type are present, the first (closest to
the board) is mapped to the selected base address. If mezzanines of same size but with
different type (parity and ECC) are present, the parity type will be mapped to the
selected base address and the ECC type mezzanine will follow. The SRAM does not
default to a location in the memory map that is contiguous with Dynamic RAM.
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 is FFE00000 for the onboard
128KB SRAM, or E1000000 for the 2MB
SRAM mezzanine. If only 2MB SRAM is
present, it defaults to address 00000000.
Size of 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.
