CHAPTER 12: LINKER
(Link processing in lk33 Ver. 3.0)
To locate a specific file beginning with a specific address
218
Combine the sections in the desired file into blocks using the -codeblock, -datablock, and -bssblock
commands and specify the address of each block using the -addr command. In this manner, a specific
section of the specified file can be located at the specified address. Multiple files can be specified, in which
case the blocks are located beginning with the start address in the order in which the files are specified.
Example: Command file
In this example, the CODE sections in sample2.o and sample3.o are defined to EXTRA_BLOCK, so that
they are located at the addresses beginning with 0x0c10000, while all sections in sample1.o and the DATA
and BSS sections in sample2.o and sample3.o are mapped to default blocks as they are located.
When specifying addresses with the -addr command, the symbols defined by the -defaddr command may be
used to specify those addresses.
Example: -defaddr EXT_ROM=0xc10000
