Currently when running the samples/watchdog/watchdog-simple.c application and forcing a kernel crash by doing: # ./watchdog-simple & # echo c > /proc/sysrq-trigger The system does not reboot as expected. Fix it by calling imx_sc_wdt_set_timeout() to configure the i.MX8QXP watchdog with a proper timeout.
