JTAG to SWD problem with STlink

Hi,

I use ST-Link/V2 programmer. I connect my stm32f407 with this circuit to my programmer.Everything works OK.

I tend to connect my JTAG connector to SWD pins in my board But when I disconnect Reset or VCC pins from my programmer ( while my board is powered up) it doesn't work and my st-link cant recognize my MCU. Here is a picture of my circuit.

How can I connect (or convert) St-link to SWD connector?0690X000006CkDiQAK.jpg

Your question is not clear. When STLINK talks to SWD, it uses SWCLK and SWDIO. Probably you have an Open407Z. So plug in the STLINK 20 Pin cable direct to the Open407 board, and you can talk JTAG or SWD.
