Question

No voltage on ST-Link v3 Minie BTB T_VCC (10) pin

Dear All,


Just now I have plugged my ST-Link v3 Minie in. Updated it via CubeIDE. All looks good.

I might have overseen something (scanned the user manual), but the BTB (CN2) connector on my ST-Link v3 Minie gives 0V voltage between T_GND(6) and  T_VCC (10) on the bottom side.

I was expecting something around 3.3V.

Or does my target board need to supply this voltage? Did I miss something? Solder Bridge?

Help is much appreciated.


Ps: CN4 STDC14 gives 2.7V on pins 3 and 1.

    Nevermind. Just supplied the target board with some voltage and it works like a charm. I figured out that the "I" in the datasheet table3, 6.1 page 10 means Input from the target board ;)
