Problem of debugging without flash

Hi

Thanks in advance for reading my post.

I am doing a project with a platform without any flash memory. This 
platform has the AM3517 processor. Before using this platform, I 
simulate it in craneboard. What I did is that I locate all sections to 
ram, Here is my linker scriptfile.

/***********************************************************************

MEMORY
{
   vectors   : org = 0x4020ffc4,   len = 0x003C
   intram    : org = 0x40200040,   len = 0x3800
   sdram     : org = 0x80000000,   len = 0x100000

}

SECTIONS
{
   .boot             : { __BOOT_START = .; *(.boot) __BOOT_END = .; . = 
ALIGN( 4 ); }> vectors

   .startup          : { __BOOT_START = .; *(.boot) __BOOT_END = .; . = 
ALIGN( 4 ); } > intram

   .text             : { __TEXT_START = .; *(.text) __TEXT_END = .; . = 
ALIGN( 4 ); } > sdram

   .rdata            : { __RDATA_START = .; *(.rodata) *(.rodata.str1.2)

   .data             : { __DATA_START = .; *(.data_4) *(.data_2)

   .svcstack         : { __SVCSTACK_END = .; . += 0x80; __SVCSTACK_START

   .undstack         : { __UNDSTACK_END = .; . += 0x80; __UNDSTACK_START 
= .; . = ALIGN( 4 ); } > intram

}


However, in the map file, I found that section 
.debug_*,.comment,.attributes are still located to the address which 
starts with 0x00000000, and this is the address where the flash is 
mapped. I add three lines in order to relocate these sections:

   .comment              : { *(.comment) ; . = ALIGN( 4 ); } > sdram

   .attributes     : { *(.ARM.attributes) ; . = ALIGN( 4 ); } > sdram

   .debug                : { *(.debug*) ; . = ALIGN( 4 ); } > sdram

and I Checked the .out file using "file" command, it says "Reading 
symbols from XXX.out, <no debugging symbols found>....done".


Can someone help me? Thanks
