Hello,


Is it possible to place a variable to a fixed memory location in gcc,
like in keil, i mean:

unsigned int dd _at_ 0x81000000;


Or I can only do it with separate section in linker script?

__attribute__ ((section (".ysection")))

and 

 -Wl,--section-start=.mysection=0x81000000


thanks 
Andrew
