Indeed - flash upload speed is not the most important speed, but the
stepping speed is 100% propo

I believe it can work under the platforms where libusb-win32 device
driver works (Win 2K, Windows XP 32/64bit, Vista 32bit). It is
not so simple

Unfortunately, I have no chips with external RAM, so I cannot test that
kind of speed - STM32 I have has only 20kB, so the upload speed result
will be worthl
Hello Freddie,
upps, in case of performance I have tested here only
download to RAM. And this looks like the same, 140 KB/sec.
Btw, an old OpenOCD, r657, had a performance of about 165 KB/sec:

Add that libusb cannot be compiled on Windows and you need to use
First of all let me state that if one considers building OpenOCD with

really don't know whether I've done that right...
Now - my question: How do I use that?
