    Are you by any chance running a memory test? If you are running from ram & test ram, you overwrite your own code/stack/heap/data segments & this will cause your console to display "^D" i.e. crash

    Same happens to me from time to time - I was linking it to some static/noise

    (I have long cable between PC and target board)

    If it is not a communication fluke, but rather application overwriting RAM memory - is there any way to diagnoze it in more detail? What memory area could be the problem here?

    I do not use heap nor any other memory allocation other than local variables inside function (stack) and global variables. How to troubleshoot this problem?

    Also, is there a way to reconnect to the system? Restart the console? I have noticed that after such ^D problem happens my JTAG uart messages are gone even after I reattach my debugger into the running process.
