Hi,

Does TI-RTOS supports software watchdog?

Please share link for more information about software watchdog (behavior and how to implement/use).

Thanks for reply.

I have referred example provided. As per my understanding, hardware watchdog is used.

I would like to know about software watchdog.

Please help me to know more in TI-RTOS.

There is no such thing as software watchdog. You must have a dedicated hardware watchdog timer which can not be turned off once enabled. User must supply the key within the watchdog window to prevent from either reset or NMI from firing off.
