Watchdog for Pi2

[DCDi]

Hi,

Are these steps still the same for watchdog on Pi2? Must be wrong....

Code: Select all

sudo apt-get install watchdog
sudo modprobe bcm2708_wdog
sudo vi /etc/modules
---
bcm2708_wdog
---
sudo update-rc.d watchdog defaults
sudo vi /etc/watchdog.conf
---
#uncomment the following:
max-load-1
watchdog-device
---
sudo service watchdog start

I am looking to do a reboot if it locks up... is there a better / easier way?

Thanks in advance.

I often wondered how a software daemon would respond if the Pi actually crashed, because surely the daemon would die with it ?

It is exactly the same watchdog block.(identical HW-side)

@ mimi - so that works for you on pi2?

I did not run Linux yet.(it works the same bare-metal side)

it should, it looks right to me.

The software sets up the hardware watchdog, then kicks it every now and then to say it is still alive. If it misses a kick the hardware doggie barks

I have watchdog working fine on my Pi 2.

Curiously, the Pi resets after the Xenon Death Flash if you enabled the watchdog.

Is there a way to test it, by forcing a stall execution on the RPi?

Xenon Death Flash is a reliable way.

haha sure. but a more scientific way for RPi's of the future that may have a better designed chip? any specific command that we can use?

Kill the watchdog daemon and it will stop kicking the watchdog and thus reset the Pi.

Hello
I am running a shell script on startup. My program hangs after sometime. Sometimes it hangs after 6-12 hours or sometimes after 2-3 days. But my PI works fine but only the program freezes when I hard reboot the PI the program works fine but as mentioned above only for 6-12 hours or sometimes for 2-3 days. Now kindly me how to setup watchdog for the shell script running on startup.
