Thanks everyone

turns out my 485 to 232 cable was not working

and this program does work

int main(void)
{       
        int fd;
        volatile unsigned char *base;

        fd = open("/dev/mem", O_RDWR | O_SYNC);
        if (fd == -1) 
        {
                perror("Error opening file for writing");
        }

        base = (unsigned char 
*)mmap(0,getpagesize(),PROT_READ|PROT_WRITE,MAP_SHARED,fd,0x22C00000);
        if (base == MAP_FAILED)
        {
                perror ("mmap");
                return 1;
        }
      
        *base = 0x01;

        close(fd);      
}


again thanks a lot for your help :)
