I'm using K64 on a custom board. Unfortunately, The NMI pin was left floating (in its default state it was connected to a pull down resistor, but this caused the board to not be flashed at all so I left it floating).
I wanted to know the hazards, if any to this situation.
As I've understood there's an internal pull up and also the Flash Configuration Field is at its default state, so both these should cover the situation. Also, the board seems to be working fine.
Am I out of the woods?
