Linker script: How to get the same size of BIN file?

Question asked by melichar.lubos on Nov 15, 2011
I need( from some reason) to get always the same size of bin file.

I've tried to create other flash-section and fill it with some value.
As last section I added following..

  .added :
  {
    FILL(0xAB);
    . = ALIGN(0x20000) - 1; //128kB
    BYTE(0xAB); //write something to say linker its really section
  } >FLASH
 
But than original linker script continue with 
  /* used by the startup to initialize data */
  _sidata = .;

  /* Initialized data sections goes into RAM, load LMA copy after code */
  .data : AT ( _sidata )
  {
    . = ALIGN(4);
    _sdata = .;        /* create a global symbol at data start */
    *(.data)           /* .data sections */
    *(.data*)          /* .data* sections */


    . = ALIGN(4);
    _edata = .;        /* define a global symbol at data end */
  } >RAM

So my bin file doesnt finished at 0x8020000 but continue with _sidata.
When I switch  _sidata = .;  with my added section, I get error.

overlaps section .added loaded at [08010694,0801ffff]
