Hi All,



I am using K21 series controller, where I do have 512 KB of Data flash and another 128K FlexNVM which I'm using as data Flash.



Here is my "test.ld" file looks like.@





/* 512 KB data flash, start with addrss 0x000000000 */

    __INTERNAL_FLASH_BASE = 0x00000000;

    __INTERNAL_FLASH_SIZE = 0x00080000;





/* 128 KB FlexNVM, start at addrss 0x100000000 */

    __INTERNAL_FLEXNVM_BASE = 0x10000000;

    __INTERNAL_FLEXNVM_SIZE = 0x00020000;


    I have 64KB of bootloader, which I can place either in First 512K of Flash or in FLEX NVM.


  In Flash :

  bootloader  (RX):  ORIGIN = 0x00000000, LENGTH = 0x00010000  /* Bootloader, 64K */


  Or in FlexNVM :

  bootloader  (RX):  ORIGIN = 0x10000000, LENGTH = 0x00010000  /* Bootloader, 64K */


  Do we have any provision that, we can place this 64K of bootloader,some part of it in first 512K of DataFlash and another part in FlexNVM.


  I'm in a situation, where some section of my .exe ,  I have to place in DataFlash and some part in FlexNVM, which is unavoidable.


  Please let me know whether its possible. in that case how would the *.ld file will look like.
