Hi everyone,
            Can anybody help me how to copy code from FLASH to RAM.Because I think we cann't
execute directly our code from FLASH with INTERRUPTS.So I need to copy my code from FLASH to
RAM.If anybody has done already this,can you give me the example codes,so that I can better
understand.Is there any other method to execute code from FLASH without copying to RAM with
interrupts.

>>> I think we cann't execute directly our code from FLASH with INTERRUPTS

I don't know why you say this. Explain please, I see no reasons about=20
that.
To copy Flash to RAm, see this :

  // Copy time critical code and Flash setup code to RAM
  memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, &RamfuncsLoadEnd -=20
&RamfuncsLoadStart);
  // Call Flash Initialization to setup flash waitstates
  // This function must reside in RAM
  InitFlash();

RamfuncsRunStart, RamfuncsLoadStart, and RamfuncsLoadEnd variables are=20
defined from the cmd file as this :

  internfuncs        :
           {
                                        main.obj(.text) // Replace with=20
all object that needed run in RAM
                        }=20
                         LOAD =3D FLASH_CODE, PAGE =3D 0  // Load in Flash
                         RUN =3D H0RAM_P, PAGE =3D 0            // Run in=20
Internal RAM
                         LOAD_START(_RamfuncsLoadStart),
                         LOAD_END(_RamfuncsLoadEnd),
                         RUN_START(_RamfuncsRunStart)
I hope it will help? There is SPRU*** Ti documentations about this, don't=20
remember the numbers.
