Is it possible to change the SWD frequency for loading a binary for a faster upload? If so how?

Changing SWD speed is described here:

Unfortunately this doesn't seem to work :).
With my own Win7 PC I can measure 1.17 MHz SWDCLK, changes to -s2000 or -s500 doesn't change anything.

The '-s' wire speed option is supported by the Code Red Red Probe and Red Probe+ emulators, but has no effect for LPCXpresso. The wire speed setting is independent of USB full or high speed. You'll want to be sure you're connected to a high speed port.
