TMS320F280048-Q1: Program will not fit into available memory and linkercmd file update

Hi,

My program gets bigger day by day. I got following error after adding some new lines to my software.

""../280048_FLASH_lnk.cmd", line 85: error #10099-D: program will not fit into available memory, or the section contains a call site that requires a trampoline that can't be generated for this section. placement with alignment/blocking fails for section ".text" size 0x2f3a page 0. Available memory ranges:"

My linker command file is as below. As I see that I have more flash banks available that I can add news to my .text lines.

SECTIONS
{
   codestart        : > BEGIN,     PAGE = 0, ALIGN(4)
   .text            : >>FLASH_BANK0_SEC1 | FLASH_BANK0_SEC2 | FLASH_BANK0_SEC3,   PAGE = 0, ALIGN(4)

    //Digital Controller Library functions
	dclfuncs		: > RAMLS4,		PAGE = 0
	ramfuncs		: > RAMLS4,		PAGE = 0


   .cinit           : > FLASH_BANK0_SEC1,     PAGE = 0, ALIGN(4)
   .pinit           : > FLASH_BANK0_SEC1,     PAGE = 0, ALIGN(4)
   .switch          : > FLASH_BANK0_SEC1,     PAGE = 0, ALIGN(4)
   .reset           : > RESET,     PAGE = 0, TYPE = DSECT /* not used, */

   .stack           : > RAMM1,     PAGE = 1
   .ebss            : > RAMLS5,    PAGE = 1
   .esysmem         : > RAMLS5,    PAGE = 1   
   .econst          : > FLASH_BANK0_SEC4,    PAGE = 0, ALIGN(4)

   ramgs0           : > RAMGS0,    PAGE = 1
   ramgs1           : > RAMGS1,    PAGE = 1

    .TI.ramfunc : {} LOAD = FLASH_BANK0_SEC1,
                         RUN = RAMLS0 | RAMLS1 | RAMLS2 |RAMLS3,
                         LOAD_START(_RamfuncsLoadStart),
                         LOAD_SIZE(_RamfuncsLoadSize),
                         LOAD_END(_RamfuncsLoadEnd),
                         RUN_START(_RamfuncsRunStart),
                         RUN_SIZE(_RamfuncsRunSize),
                         RUN_END(_RamfuncsRunEnd),
                         PAGE = 0, ALIGN(4)

   /* crc/checksum section configured as COPY section to avoid including in executable */
   .TI.memcrc          : type = COPY

}

I can add a new bank to my text, but I don't know how to modify other lines or what I should do in a correct way. 

1) Could you please help me how to add a new flash banks to my software?

2) If I add FLASH_BANK0_SEC4, which lines also should I update according to it? Consider updating .text line as below;

.text            : >>FLASH_BANK0_SEC1 | FLASH_BANK0_SEC2 | FLASH_BANK0_SEC3 | FLASH_BANK0_SEC4

3) If you see any problems in my linker command lines, could you please give feedback by totally reviewing it? I need to organize flash and ram properly.

Thank you.
