linker sections for RTS/

Started by Sri ●January 5, 2006
Hi,
 
I want to know that how can I create user defined sections( to link at a particular location in memory) for the different RTS and CSL library routines code used in my code. I know that by default all the RTS and CSL code goes into the .text section , I can modify the linking destination for whole .text section.
But what is the procedure, if I want to move some selective CSL/RTS routines(say EDMA and McBSP) to a user defined section and and put all others in their usual .text section.

You could place RTS sections off-chip by following something similar to the following piece of code (part of Linker Command File):
 

/*

*/

/* RTS code

placed off chip */

/*

*/

.rtstext {

lrts6200.lib(.text) } > EXT0

/*

*/

/* RTS data

undefined sections placed off chip */

/*

*/

.rtsbss {

lrts6200.lib(.bss)

lrts6200.lib(.far) } > EXT0

/*

*/

/* RTS data

defined sections placed off chip */

/*

*/

.rtsdata {

lrts6200.lib(.const)

lrts6200.lib(.switch) } > EXT0

 
Check out section 9-9 of programers guide(spru198.pdf) for more details.
