## Setup
```shell
sudo ln -s $PWD/boot/config.txt /boot
sudo ln -s $PWD/etc/modprobe.d/bcm2835-wdt.conf /etc/modprobe.d
```
## How to see if a watchdog timer works properly
First, check the logs.
```shell
sudo dmesg | grep bcm2835-wdt
sudo dmesg | grep systemd | grep watchdog
```
```
[ 1.949143] bcm2835-wdt bcm2835-wdt: Broadcom BCM2835 watchdog timer
```
```
[ 9.389119] systemd[1]: Using hardware watchdog 'Broadcom BCM2835 Watchdog timer', version 0, device /dev/watchdog
[ 9.401138] systemd[1]: Set hardware watchdog to 5s.
```
Then, try dropping a fork bomb.
```shell
:(){ :|:& };:
```
If the watchdog timer works fine, the system should reboot automatically in a couple of minutes.
