Section Placement - Texas Instruments C28 Series Student Manual

Creating a Linker Command File

Section Placement

You can specify how you want the sections to be distributed through memory. You would use the
following code to link the sections into the memory specified in the previous example:
SECTIONS
{
.text:> FLASH
.ebss:> M0SARAM
.cinit:> FLASH
.stack:> M1SARAM
}
The linker will gather all the code sections from all the files being linked together. Similarly, it
will combine all 'like' sections.
Beginning with the first section listed, the linker will place it into the specified memory segment.
