Genuine STLINK-V3MINIE doesn't work, but clone STLINK-V2 works

[Chupacabras]

I'm trying to make genuine STLINK-V3MINIE to work, but without success.

The target device is STM32F103C8T6.

VCC is connected to T_VCC (pin 3 of STDC14)

SWCLK is connected to T_SWCLK (pin 6 of STDC14)

SWDIO is connected to T_SWDIO (pin 4 of STDC14)

RESET is connected to T_NRST (pin 12 of STDC14)

GND is connected to GND and GNDDetect (pins 5, 7, 11 of STDC14)

STM32CubeProgrammer is properly detecting STLINK-V3MINIE, even shows voltage of the target.

But when I try to connect to target, it gives message:

Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication

This is text from console:

  12:56:46:283 : UR connection mode is defined with the HWrst reset mode
  12:56:46:837 : ST-LINK SN  : [redacted]
  12:56:46:838 : ST-LINK FW  : V3J16M7

  12:56:46:839 : Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication
  12:56:46:876 : Disconnected

I tried another PC, but with the same result.

When I connect clone STLINK-V2 instead of genuine STLINK-V3MINIE, I'm able to connect to target MCU, and download program to target.

This is the output from console:

What is the problem with STLINK-V3MINIE?

How to make it work?

It's pretty frustrating that clone works and genuine debugger not.

[Chupacabras]

Yes. Case closed.

But ST isn't the only user of ARM Cortex cores so it makes sense not to connect to a different M3.

What made you think this was an ST Chip? Was the number STM32F103C8T6 on the chip or package somewhere?
