Using Synmap to Enable and Configure the Watchdog Timer

The TC-6110 comes with a default watchdog timer (a Computer Operating Properly/COP timer) that will initiate

a soft reboot whenever the system or a specific program freezes for a specified time period. The watchdog

timer has only two Synmap OIDs associated with it: watchdogPeriod and watchdogStatus. The value for

watchdogPeriod sets the countdown interval during which the watchdog timer must receive a COP

notification from the OS kernel; if it does not receive a COP notification during this interval, the watchdog will

reboot the system.

The default value of watchdogPeriod is 0, which leaves the watchdog disabled. To enable the watchdog timer,

you need to set the scanning interval to a non-zero integer between 1 and 255; this number will set the number

of seconds that will pass following a system (or application) hang before the watchdog reboots the platform.

After setting a time interval for the watchdog, the OID watchdogStatus will automatically change to 1, to

indicate that the watchdog timer is enabled. Once enabled, whenever the kernel fails to deliver a COP signal

during the specified time period the watchdog will automatically initiate a soft reboot.

The following table shows the watchdog OIDs.

Item Name OID Access Value

watchdogPeriod 1.3.6.1.4.1.8691.17.1.6.6.2.1 read-write An integer between 1 and 255

representing the timeout period in

seconds (E.g. 30 = 30 seconds)

watchdogStatus 1.3.6.1.4.1.8691.17.1.6.6.2.2 read 0 represents Off, 1 represents On
