3.4.2 Map Files

Map files show where sections are linked in memory. Specifically,

they show the names and address ranges of sections and global

variables.

You can cause the linker to generate a map file of your code by

specifying the –m option on the command line or in the linker

command file.

By examining the map file generated by the linker, you can verify

that the sections of your program are mapped into the proper

locations in memory.

For more information about map files, see subsection 13.3.8,

Create a map file (–m filename option) , in the TMS320C80 (MVP)

Example 3–1 is a sample PP C program that will be used to illus-

trate how code written for the 'C82 can be made to run on the 'C80

through linking. The program calculates the dot product of two

vectors, A and B. The source code needs to compiled only once;

the object file then only needs to be linked with the proper linker

command file for each device.
