[ts-7000] segmentation fault :(

["Hatem Mohamed" <>]

Hi every body 
I have Ts-7300 , I wrote this C code on it and it is compiled successfully  but when I tried to execute the file I get this message  " segmentation fault "
all I wanted from this code was to make pins from Dio0 ~ Dio7  all zeros. 

#include<unistd.h>
#include<sys/types.h>
#include<sys/mman.h>
#include<stdio.h>
#include<fcntl.h>
#include<string.h>
int main()
{
   volatile unsigned char *P1DR;
   unsigned char *start;
   int fd = open("/dev/mem", O_RDWR);
   start = mmap(0, getpagesize(), PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0x80840004);
   P1DR = (unsigned char *)(start + 0x00);
 *P1DR=0x00;
  close(fd);
   return 0;
}


that was my first question 

the second question 

can I make any pin in the 55 Dio zero or one alone I mean is there any function can do that directly ??
