How to use watchdog with C?

Can anyone give a hint or code example, how to activate and feed the
watchdog of the mini2440?

thanks

Hi,

take a look at the following link. There you can download a user's manual
where all the register names and its features are described:

Hi!
I found a simple solution if anyone is interested:


To start the watchdog, you need to open /dev/watchdog as a file for
writing. Feeding the watchdog (and resetting) is done with writing
any character to the file.

simple example from
http://www.linuxhq.com/kernel/v2.4/19/Documentation/watchdog-api.txt

int main(int argc, const char *argv[]) {
   int fd=open("/dev/watchdog",O_WRONLY);
   if (fd==-1) {
      perror("watchdog");
      exit(1);
   }
   while(1) {
      write(fd, "\0", 1);
      sleep(10);
   }
}

I'm interested...

Thanks for share the code :D
