Ah, thank you. I thought as much, but sometimes a silicon bug makes a
microcontroller less reliable than it ought to be. Or a garbled command
can be mistaken for the command to permanently turn off a debug port.
That's usually very unlikely, but if it only differs one bit from a
common programming command... If this happened in practice, it would
probably be common knowledge for regular users of the µC.

That's good to know, I'll simply use my TUMPAv1 then.

I don't have a lead on that, on a QFN package.... *ba dum tsh*. Maybe
it's possible, but I'll use the SWD port first.

Thanks again!

Peter.
