HOW TO place INTERRUPT SERVICE ROUTINE generated by embedded coder for TMS320c28x processor into "code_ramfuncs" section

Best Answer

In my opinion, you can set the Configuration sets to do you want.
1.you can place the folloing statements in the Code Generation->Custom Code->insert custom C code in generated->Source file
#pragma CODE_SECTION(ISR_Function, "ramfuncs")
Then, this statement will be inserted to you model.c code.
2.Next,choose "Boot From Flash(stand alone execution)"in the Hardware Implementation Panel.This will make all of the genearted code run in flash. you can check the Simulink's c28335.cmd with the "Edit..", like this:
 % #if BOOT_FROM_FLASH
SECTIONS
{
    .vectors:    load = 0x000000000
    .text:   > FLASH, PAGE = 0
    .switch:     > FLASH, PAGE = 0
    ……
    codestart:   > BEGINFLASH, PAGE = 0
    csmpasswds:  > CSM_PWL, PAGE = 0
    ramfuncs:   LOAD = FLASH,
      RUN = RAML4L7, 
LOAD_START(_RamfuncsLoadStart),
      LOAD_END(_RamfuncsLoadEnd),
      RUN_START(_RamfuncsRunStart),
      PAGE = 0
}     #else
SECTIONS
{
    .vectors:    load = 0x000000000
    .text:   > RAML4L7, PAGE = 0
    .switch:     > RAML4L7, PAGE = 0
    ……  
    codestart:   > BEGINRAM, PAGE = 0
    csmpasswds:  > CSM_PWL, PAGE = 0
    csm_rsvd:    > RAMM0, PAGE = 0
    ramfuncs:    > RAML4L7, PAGE = 0
 …
}
#endif
 Hope this will be helpful.
