Can't connect to target! Two months ago work, now it don't, on two computers windows 8,

[FLast.1]

There is no fully communication with ST-link V2 with STM32 Link utility program.

All drivers installed properly, signed.

Firmware upgrade mode works, programming mode not.

FW version: V2J33s7

I set low rate speed 100 kHz, try all reset options - never work.

STM target information - detection fail

What I can do now?

Make sure pin 1 or 2 is connected to board supply, and target voltage is reporting correctly.

Would need more info on target boards and atta​chment to understand why.
