    Hi,

    If you define an exception stack, then it should be the target stack.

    If no, it should be system stack...

    Thanks for your reply David_Cai,

    but now I have this problem: in the system library page, if I include ucosii I can't set the option "use a separate exception stack".Is it normal and why?

    tnx in advance

    bye

    I think it's normal.

    Maybe it will lower system complexity.
