[ts-7000] segmentation fault

["David Kadjo" <>]

Hi all,

I'm new to the TS7200 board.I have written the program below to turn 
on the LED on the boards. I get a "segmentation
fault" error every time I run it. Could any body help ? 

thanks 

#include<unistd.h>
#include<sys/types.h>
#include<sys/mman.h>
#include<stdio.h>
#include<fcntl.h>
#include<string.h>

int main(void)
{
        volatile unsigned char *LED, *start;
        int fd=open("/dev/mem",O_RDWR);

        start=mmap(0,getpagesize(),PROT_READ|PROT_WRITE,
                        MAP_SHARED,fd,0x80840020);
        LED=(unsigned char *)(start +0x00);


       *LED = 0x01;  //turn on led

        close(fd);
        return 0;
}
