Unused microstore
Unused microstore can be initialized by using the controls
in the
Fill options for unused microstore
area.
To leave the unused microstore unchanged, select
Do not
fill.
To fill the unused microstore:
1. Select
Fill with default pattern (0xe000010000)
.
0xe000010000 for the IXP2400, IXP2800 network processors.
or
2. Click
Fill with custom pattern
and type a 10 character hex pattern to be used. Make sure the
number begins with “0x.”
Reserved memory segment for variables
The reserved memory segment for variables provides the Linker with information needed for
allocating memory to be used for variable data storage.
Scratch offset
The Scratch offset is a parameter sent to the Linker. The Linker uses scratch memory starting at the
base address, allocating as much memory as needed up to the Scratch offset size for variables.
Scratch segment size (bytes)
The Scratch segment size is a parameter sent to the Linker. The Linker reserves as much scratch
memory as necessary for variables up to the segment size.
SRAM offset
The SRAM offset is a parameter sent to the Linker. The Linker uses scratch memory starting at the
base address, allocating as much memory as needed up to the SRAM segment size for variables.
SRAM segment size (bytes)
The SRAM segment size is a parameter sent to the Linker. The Linker reserves as much SRAM as
necessary for variables up to the segment size.
DRAM offset
The DRAM offset is a parameter sent to the Linker. The Linker uses DRAM memory starting at the
base address, allocating as much memory as needed up to the DRAM segment size for variables.
DRAM segment size (bytes)
The DRAM segment size is a parameter sent to the Linker. The Linker reserves as much DRAM as
necessary for variables up to the segment size.
