Watchdog on iMX28

[dgotfroi]

Hello,

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) ?

Many thanks,

Damien

Hi Damien

I would suggest to check Chapter 27 Watchdog (WDOG) Driver
