Hello,
I am a newbie to Embedded systems.
We are using Linux.
watchdog timer implementation as follows:
In the software setting the watchdog timer and on timeout it clears the hardware register which is used by the hardware to check if the system needs to be reset or not.
But we are facing some problem in the hardware ( for example video is freezing and the system hangs). In this case how to make the system reset ?
Will watchdog timers be used only for the problems in Software ? If so how to reset the system in case of hardware failures ?
Thanks
