Hi Andreas
I have access to a standalone Rlink, an Olimex STM32-P103 board and
a Raisonance REva STM32 connectivity board which has an onboard
Rlink.
I've applied your patches and built OpenOCD on Linux with success. A
quick test revealed no problems but the test program I've used is
too small to see any speed differences when flashing. I can do more
tests, some hints for what to look for would be welcome.
Hi Andreas
I recognized that I've applied only the five patches from the patch set
concerning "Flash program speedup through asynchronous algorithms" when
I did testing. This patch works for me without problems on Windows /
Mingw and Linux, both with the embedded RLink of the Raisonance REva
board as well as with a standalone RLink.

Stepping is still slow on Windows.
I have now also applied the RLink "RLink interface speedup and fixes"
patch series and run into some problems:
On Linux with the standalone RLink I get:

Patches 1/7 to 4/7 work ok, the problem is caused by patch 5/7

There seems to be an known issue with libusb-win32:

BTW I'm using libusb-win32 1.2.4.0
