Unless specified by this command, the blocks are located in the manner shown below.
CODE block: Located from 0x0c00000
DATA block: Immediately after the most-significant CODE block
BSS block:
When specifying multiple blocks, be sure to enter at least one space, tab, or line feed
between <block> entries.
Block names in { } can be written in two or more separate lines.
Example) -addr IN_ROM
Up to 256 blocks can be defined.
A block name can be up to 130 characters and is case-sensitive.
An object file name can be up to 256 characters, including the path.
Up to 256 blocks can be specified in { }.
The symbol name in format 2 must be defined by the -defaddr command before it can be
used.
The block names to be specified by -addr, except for default block names, must first be
defined by the -XXXblock or -uXXXblock command described above.
The addresses specified here must be aligned to the address boundaries set using the
-align command. Specifying a misaligned address results in a warning, in which case the
'n' low-order bits are ignored. Addresses, by default, are aligned on 4-byte boundaries.
Defining two or more instances of the same address (or symbol) results in a warning, in
which case only the first command defined is effective.
Example) -addr 0x50000 { BLOCK1 BLOCK2 }
Specifying duplicate block names in one -addr block or specifying the same block name
in two or more -addr blocks results in an error. However, block names that include '@'
and those do not are assumed to be different.
Example 1) -addr IN_ROM { BLOCK1 @BLOCK1 }
Example 2) -addr IN_ROM { BLOCK1 BLOCK2 BLOCK1 }
Example 3) -addr IN_ROM { @BLOCK1 BLOCK2 @BLOCK1 }
Example 4) -addr IN_RAM { BLOCK1 BLOCK2 BLOCK3 }
Multiple blocks that contain the same object definition cannot be specified within the
same -addr definition or other -addr definitions.
Example 1) -codeblock BLOCK1 { boot.o main.o sub.o }
Example 2) -codeblock BLOCK1 { boot.o main.o sub.o }
{
}
-addr 0x50000 { DEFAULT_CODE }
At the beginning of the internal RAM (0x0000000)
-addr EXT_RAM { BLOCK4 BLCOK1 }
-codeblock BLOCK2 { main.o }
-addr 0x800
{
}
-codeblock BLOCK2 { comp.o }
-codeblock BLOCK3 { main.o }
-addr 0x800
{
}
-addr 0x1000
{
}
