Memory Map Files
File Formats
The linker can output memory map files (.xml), which are ASCII text files
that contain memory and symbol information for the executable files. The
.xml file contains a summary of memory defined with the MEMORY{} command
in the .ldf file, and provides a list of the absolute addresses of all
symbols.
Loader Output Files in Intel Hex-32 Format
The splitter utility can output Intel hex-32 format files (.ldr). The files
support 8-bit-wide PROMs and are used with an industry-standard
PROM programmer to program memory devices. One file contains data
for the whole series of memory chips to be programmed.
The following example shows how the Intel hex-32 format appears in the
loader’s output file. Each line in the Intel hex-32 file contains an extended
linear address record, a data record, or the end-of-file record.
:020000040000FA Extended linear address record
:0402100000FE03F0F9 Data record
:00000001FF End-of-file record
Extended linear address records are used because data records have a
4-character (16-bit) address field, but in many cases, the required PROM
size is greater than or equal to 0xFFFF bytes. Extended linear address
records specify bits 31–16 for the data records that follow.
Table A-2 shows an example of an extended linear address record.
Table A-3 shows the organization of a sample data record.
Table A-4 shows an end-of-file record.
