Re: [Paparazzi-devel] ST-Link_V2

[Jake Stewart]

The JTAG uses the same processor pins as the SWD (st-link).  The ST-Link V2 
will run directly with OOCD, so it will probably work without any trouble.  You 
might have to mess with some OOCD configuration settings though.

I have a V1 st-link and the information out there is a bit confusing on how to 
get it working.  Most of the solutions I've seen require various amounts of 
recompiling and/or using custom OOCD versions.  It's more work than I'm looking 
to do, so my solution is to run a GDB server in windows.  I'm still hoping 
someone can give me a little more info on getting paparazzi to use that setup, 
but I'm sure I'll figure it out eventually.

>From the F103 manual...
"The JTAG TMS and TCK pins are shared with SWDIO and SWCLK, respectively"

So you should just have to plug SWDIO -> TMS and SWCLK -> TCK.
