STM32F302R8: No Ulink device found

Hi, I'm using an STM32F302R8 board to do some basic DSP work. I've been using my desktop with windows 7 on it for a while and I'm able to use Keil V5.14 to program the board no problem. 

However, I have to move to using my windows 8.1 laptop, I'm unable to program the board. When I connect the board though, i do get the folder popping up showing that windows is able to see the device no problem. Also the driver is installed fine and ST-LINKV2 is showing up in device manager. 

I get an error saying ' NO Ulink device found'. When I check Cortex-M Target Driver Setup > Debug, the Debug Adapter field is empty. 

Is this a known issue with either KEIL or ST-LINK and windows 8.1? that's the only delta i can think of between my working and non-working setups.

U-LINK != ST-LINK, pick the right debugger

Hi Clive1,

     Here is a visual representation of the issue. 

      on my working system, i get: 

and on the other system, using the same board ( even the same USB cable! ) i get: 

Hope that is clearer than my original post.

Your post was clear, but the ST-LINK is still not a

U-LINK

, you still need to select the right debugger in the debug pane, then the settings will work.

Do you mean the debug pane shown in the picture above? as you can see, there is nothing listed there at all! 

in the first window, it defaulted to the ST-LINK shown. in the 2nd window, it doesnt show anything at all, which seems to be the cause of the problem. 

is there somewhere else i need to select this for it to show up here?

You're making this far more complicated than it is. Pick the right debugger and it will find it.
