Hello,


Is it exist simple method to place an ARRAY to a fixed memory location 
in gcc,like in Keil:
const unsigned char eeprom[EE_SIZE]_at_EE_ADDR_L;
 
For a variable
unsigned int dd _at_ 0x81000000;
 
previous answers suggested:
int * dd = ((unsigned int *)0x81000000);

Have I to use separate section in linker script?

Thanks
Zoltan Gobor

You don't have to.  You can also use a pointer to access an array:

unsigned char *eeprom = (unsigned char *)0x81000000;
...
i = eeprom[34];

and to access a struct:

struct eedata
{
  int ee1;
  int ee2;
};

struct eedata *pe = (struct eedata *)0x81000000;
...
i = pe->ee1;
