Watchdog

I was posting about the watchdog device on the raspberry pi a few days ago and how to solve a specific error with the configuration on the pi. In the meantime I had the watchdog device running for a few days and it worked … kind of … One should know, that the watchdog devices halts the pi immediately, so it’s not a clean shutoff but more like you would pull the power plug of the pi. ...

Seen that error before? Possibly on a Raspberry Pi 2/3? Google seems to have problems guiding you to the right solution, so here it is: Add watchdog-timeout = 15 to your watchdog.conf file. Why is that? The Broadcom BCM2835 Watchdog timer only supports 15 seconds timeout ;)
