I am not having too much joy with this approach so far, maybe I don't know
enough about ARM processor states. I had this trigger a reset once

If this is of interest to anyone please let me know if there is something you'd
like me to try / information to capture next time.

If anyone has information about using the IcePick to reset the DM355

Oh, I just found this:

Which suggests that TI won't give out the information needed to use the
