No problem. If you avoided top-posting too, and didn't omit the
mailing list from Cc, that would be even nicer ;)

Yes, that's an optimisation artifact indeed, quite common. Was the
function itself called only once, and did you see FIFO counter
increase by 2 right after that? Please also try Andreas's suggestion
to collect a -d3 log. If by any chance you have access to some other
adapter (not stlink) it would be nice to compare. I wonder if it's
stlink's firmware itself doing double read in the end.
