ENV - Set Environment

Memory Size Ending Address 00100000 Default Ending Address is the calculated size
of local memory.
Note
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
the same size but 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). Must be a
multiple of the Dynamic Memory board size,
starting with 0. Default is $0.
Size of Parity Memory 00100000 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 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 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 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 The size of the SRAM type memory present.
The default is the calculated size of the
onboard SRAM or an SRAM type mezzanine.
