problems in relocating variables

["P.S.Ravi Kiran" <psrk at cdotb dot ernet dot in>]

sir, 
  
  I am using a gcc cross compiler for 68302. 
 I am having problems locating some variables at addresses I want. 
 we have a file  db.c 
 like this 
  

// db.c 
   some_struct x[][]; 
   some_Struct y[][]; 
     ..................... 
     ...................... 
//end of db.c 

and I want to locate all of these arrays at 0x500000. 
and other global variables from 0x200000 
so I defined in my LD script 
 SECTIONS 
{ 
.................. 
.............. 

.bss  0x200000 : 
 { *(.bss) *(COMMON) _bend = . ;} 

db 0x500000  : 
  { db.c } 
............... 
} 

but the compiler is locating the variables in db.c in the COMMON section
in 0x200000 
 and 0x500000 is empty.  (as observed in the generated map file ) 

can anyone please tell me how to do this ? 

Thankyou very much 

Sincerely 
Ravi Kiran
