Hi I'm working with this code in order to control relay switch, (the TS-Relay8 Board) on a TS7800,
#include <netinet/in.h>
#include <arpa/inet.h>
#include <unistd.h>
#include <time.h>
#include <ctype.h>
#include <sys/mman.h>
#include <fcntl.h>
#define RELAYBASE 0xEE000140
int main()
{
volatile unsigned int *PBDR;
unsigned char state;
unsigned char *start;
int fd = open("/dev/mem", O_RDWR|O_SYNC);
start = mmap(0, getpagesize(), PROT_READ|PROT_WRITE, MAP_SHARED, fd, RELAYBASE);
PBDR = (unsigned int *)(start + 0x02);
state = *PBDR;
printf("Result: %x\n",state);
return 0;
}
Can be compiled, but return Segmentation Faults when it runs. Instead, with the shell I can do peek16 0xEE000142 with no problem.
Any ideas please?
