    USB watchdog using SOF ISR and Timer

    vinu.narayanan_1473901

      Hi All , 

         

      I want to implement a WDT functionality for USB using SOF ISR .  I need to start and stop SOF monitoring during some conditions . 

         

      What I thought of using a timer and resetting the timer in SOF ISR , If timer is not getting reset , I  am hoping to get a timer interrupt . I don't want to call any API s from ISR . I saw one reset Pin in the top design , is it possible to make use of that ?

         

      What I   an expecting is a signal kind of hardware connection to timer reset , that can be set from ISR easily  . Is it possible ? or there is any better way ?

          Its not wise to use abbreviations in an international community, the dictionary lists several pages for "SOF" including "Sudent Orchestra Festival".

             

          I saw one reset Pin in the top design  Which project are you referring to?

          Easiest to help you would be when you post your complete project, so that we all can have a look at all of your settings. To do so, use
          Creator->File->Create Workspace Bundle (minimal)
          and attach the resulting file.
