Hi,

Please refer to different watchdog implementations to know more about this. The text should be available online. So basically, one external watchdog has to be utilized to catch any abnormal device behavior.

Thanks,

Pradipta.

Hi,

The AWR2243 has is a front-end device. It requires an external host to communicate with it. The external host may implement the watchdog.

We cannot add weblinks in the forums. You will need to do a search on the web to find more information on watchdog and its implementation in general. This will you give you more idea on this requirement.

Thanks,

Pradipta.
