Using OpenOCD for debugging STM32F1xx Discovery board (ST-Link)

I got some problems getting OpenOCD to communicate with my STM32F100RB Discovery board (it uses ST-Link).

I am not used to working with open source tools, and therefore I've never had problems programming and debugging my embedded platforms. In the past week I've had more problems than I had ever imagined, just trying to get an IDE + FreeRTOS + Debugging up and running.

I have now decided to use Eclipse + Sourcery G++ Lite + OpenOCD for my embedded application. I have a little application compiled (good start...) and are now trying to program and debug using OpenOCD. When I am doing that I get the following error: 

Open On-Chip Debugger 0.7.0-rc2 (2013-04-28-12:55)

Error: Debug adapter doesn't support any transports?
Runtime Error: embedded:startup.tcl:20:

in procedure 'ocd_bouncer' 
at file "embedded:startup.tcl", line 20

I have no idea where to start, please help. Also: if anyone has a better opensource/free IDE for STM32 which "supports" FreeRTOS (i.e. for which a demo/template is available), I'll be very happy to hear about it :)

Edit:

Ok, I think that I used the wrong config-file in the first try. Now I am getting this instead:

C:\OpenOCD\openocd-0.7.0-rc2\bin>openocd-0.7.0-rc2.exe -f stlink-v2.cfg

Why don't you just use the available board configuration? scripts/board/stm32vldiscovery.cfg This is for exactly your board. This way you won't need to specify interface and chip, just the board:

openocd-0.7.0-rc2.exe -f board/stm32vldiscovery.cfg
