CN3 breaks the connection to the user programmable STM32 so you connect another board to CN2, the SWD connector. You remove both jumpers, see pg 11 of the user manual.
There are only 4 pins on CN2, and two of those are power. The other two are TCK/SWCLK and TMS/SWDIO, you can see these, and how they would connect to an STM32, by reviewing the VL Discovery schematic. Is this something you have looked at? http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/USER_MANUAL/CD00267113.pdf Realistically you'd probably want to have a reset too. There are some better JTAG/SWD solutions out there.
