STLink V3MINIE no target voltage

Seba52

I have the STLink V3MINIE. When connected to the PC the red power LED is on. But I can't program any device because there is not target voltage. 

ST Prog (v2.17) shows Target voltage 0.00 V

How can I fix this? Is there a jumper or solder connection missing on the stlink? Or is the board damaged?

We will use the TagConnect TC2030 https://www.tag-connect.com/product/tc2030-ctx-nl-stdc14-for-use-with-stm32-processors-with-stlink-v3 to connect the stlink v3minie to the PCB, that's why the power on the T_VCC pin is needed. I think, I will find a solution to achieve this. 

 

The TagConnects are nice - basically a portable "bed-of-nails".

That one has 6 pins.

You need GND, SWDIO, SWCLK;

Useful to have are also NRST and T_VCC;

So that leaves you one spare to use as a supply to your target

Yes, they are very handy. All the essential signal are there, also SWO. I will try to wire the 3.3V to T_VCC on the stlink v3minie board as I mentioned above. Than it should be possible to program the pcb if not mounted to anything else.
