Hello Klaus,

    As far as i know, you can set the VMA as your RAM address and LMA
as your flash memory that will give your expected behavior.

 Here is how you can do that

PHDRS{
     -------------
     seg_flash PT_LOAD ;  /* if you want to specify the segment */
      --------------------
   }
MEMORY{
      -------------------
 ---------------------------
      ram_mem : ORIGIN = xxxxx, LENGTH = xxxxx
     flash_mem : ORIGIN = xxxxx, LENGTH = xxxxx
--------------
}

SECTIONS{
 -------------------------
----------------------
FLASH_RAM :{
               ---------------------
             -----------------------
          } >ram_mem AT>flash_mem :seg_flash
    ------------------
----------------------
}

Am I wrong?

Regards,
Ram
