raspberrypiKeep a Headless Raspberry Pi Alive with the Built‑in Watchdog and systemd
When you run a Raspberry Pi without a monitor, a frozen system can lock you out. This guide shows how to use the Pi’s hardware watchdog, wired into systemd, to automatically reboot the board, and explains the limits and practical checks you need.
Using Raspberry Pi's Built‑in Hardware Watchdog for Automatic Recovery
Enable the Raspberry Pi’s built‑in bcm2835‑watchdog driver and a small userspace daemon to get automatic recovery from software hangs without extra hardware.
