Here is a useful tutorial from Logic Supply on how to set up the embedded watchdog timer on your BeagleBone Black.
Computers running critical applications, often need a way to be reset if an unexpected event causes the system to become unresponsive. Getting a computer back up and running in a remote location can be costly and frustrating. The BeagleBone Black is being used in more applications, and (unattended) situations where an occasional reset may be required from time-to-time. Fortunately, there is an easy way to do this!
A watchdog timer is a circuit that requires a periodic ‘wake up’ signal or else it generates a reset pulse.
(Feed-me or I will bark!).
Each Tuesday is BeagleBone Black Day here Adafruit! What is the BeagleBone? The BeagleBones are a line of affordable single-board Linux computers (SBCs) created by Texas Instruments. New to the Bone? Grab one of our Adafruit BeagleBone Black Starter Packs and check out our extensive resources available on the Adafruit Learning System including a guide to setting up the Adafruit BeagleBone IO Python Library. We have a number of Bone accessories including add-on shields (called “capes”) and USB devices to help you do even more with your SBC. Need a nice display to go along with your Bone? Check out our fine selection of HDMI displays, we’ve tested all of them with the Beagle Bone Black!
