Scatter file region placement issue

Hi,

I am trying to create a scatter file and using ARM 5.01 tools. I am facing a strange issue with RW section.

here is the scatter file

LR2 ImageLimit(LR1)
{
   ER1_RO_REGION  +0x0
  {
        timer.o (+RO)

  }

  ER2_ZI_REGION  +0x0 ZEROPAD
  {
        timer.o(+ZI)

  }

  ER3_RW_REGION  0x00600000
  {

   timer.o(dummy_name)

  }
 ER4_UNINIT_REGION  +0x0
  {
    *.*(ER4_UNINIT_SECTION)
  }
}

in timer.c I have the following
__attribute__((section("dummy_name")))
int global_dummy_array[] = {1,2,3,4,5};

Now if load the generated elf format on simulator I see the array shows all 0
however if i change the base address of ER3_RW_REGION to +0x0 I can see the array values as set in the file.

can someone help understand what is going on ?
