      As you can see there is some crash dump coming from firmware on the CONSOLE prints but we couldn't understand what that dump means. Any help regarding this issue will help us a lot as we are currently stuck on this issue from proceeding.

       

      Attaching the complete log for your reference.

       

      Here are the software version details:
