A somehow working software + emulation of this chip, called "softdog" also exists in Linux. + A reboot can be triggered by some other criteria too. + +This script installs a RedHat-style initscript, but you can run it from +/etc/rc.d/rc.local too. + +This daemon needs a proper kernel driver to work. +Some machines, such as raspberry pi 4b, provide /dev/wachdog by default. +Intel systems might require editing /etc/sysconfig/watchdog to have +START_MOD_CMD="modprobe iTCO_wdt" and + +You can try "softdog" if nothing better is available. |
