.text section allocation

Gary H

I am realativly new to the CCS and could use a little help on the syntax of how to designate the .text section to be more than one segment in Flash.

Below .text is sectioned into FLASHA only. How do I spread .text across more Flash such as FLASHC and FlashD?

SECTIONS
{
   /* Allocate program areas: */
   .cinit            : > FLASHD,     PAGE = 0
   .pinit            : > FLASHD,     PAGE = 0
   .text             : > FLASHA,     PAGE = 0

You can "split" the .text section among multiple memory regions using the following syntax:

.text : >> FLASHA | FLASHC | FLASHD, PAGE = 0

Or you can tell it to allocate as a whole into the first memory range in which it fits completely, by doing this:

.text : > FLASHA | FLASHC | FLASHD, PAGE = 0

Please refer to Section 7.8.5 and 7.8.6 of the C28x Assembly Language Tools Users Gude, http://www.ti.com/lit/spru513 for more details.

In addition to Aarti's suggestions, you can also merge the flash sectors in the MEMORY description. Just keep in mind that a sector is the smallest amount that can be erased. This may become important if you partition code with field upgrades in mind.
