I enabled "Freescale STMP3XXX & i.MX23/28 watchdog" in the virtual/kernel menuconfig of my linux image.
So, now, I have "/dev/watchdog" device.
If I write something into "/dev/watchdog", the watchdog start and I need to write something every 15 sec max otherwise my board restart.
But I would like to know if it's possible to stop the watchdog ? And if I can change the timeout delay (15 sec) ?
