查看看门狗

ubus call system watchdog

root@Widora:~# ubus call system watchdog
{
        "status": "running",
        "timeout": 30,
        "frequency": 5
}
root@Widora:~# 

如何验证?最暴利的方法就是查看门狗计数器是否在循环的倒计时。 reg r 10000128

root@Widora:~# reg r 10000128
add:0x10000128 = 0x741d
root@Widora:~# reg r 10000128
add:0x10000128 = 0x708e
root@Widora:~# reg r 10000128
add:0x10000128 = 0x6eb6
root@Widora:~# reg r 10000128
add:0x10000128 = 0x6d15
root@Widora:~# reg r 10000128
add:0x10000128 = 0x6b53
root@Widora:~# reg r 10000128
add:0x10000128 = 0x69a7
root@Widora:~# reg r 10000128
add:0x10000128 = 0x67f1
root@Widora:~# reg r 10000128
add:0x10000128 = 0x7127
root@Widora:~# 

停止系统喂狗

ubus call system watchdog '{"stop": true}'

root@Widora:~# ubus call system watchdog '{"stop": true}'
{
        "status": "stopped",
        "timeout": 30,
        "frequency": 5
}

停止后,默认是30秒系统重启

恢复系统喂狗

root@Widora:~# ubus call system watchdog '{"stop": false}'
{
        "status": "running",
        "timeout": 30,
        "frequency": 5
}
