Do you have another (non-STLink) dongle to try with? It apparently fails
during init of the STLink, when it hasn't done much, if anything, with the
target. So I suspect the problem lies either in the STLink init code (and I
cant see why it should matter at that point which flash size you have) or
not in OpenOCD at all. Can you use another software tool, for example some
flashing utility for the STLink to verify if it's possible to make it work
at all?
