External STLink V2 connection to Nucleo-STM32H723ZG

[Davit_Imnaishvili]

Hello, the embedded STLink of my  Nucleo-STM32H723ZG board has stopped functioning when I was trying to set up the Vref and I'm trying to use an external STLink V2 programmer to write code into the microcontroller. The problem is that I can't find the proper connection instructions in any of the manuals. Here are the 10 pins of my regular STLink V2 programmer:

RST, SWDIO
GND, GND

SWIM, SWCLK

3.3V, 3.3V
5V, 5V

Where do I have to connect the pins of STLink on this board?

[LCE]

UM2407, page 17 - use the MIPI-10 debug connector, but first check the jumper.

I have that board, but I haven't tried that!

@Davit_Imnaishvili But please make sure that you don't try one of those colourful tin can ST-LINK/V2, because they are fakes with fake MCUs and usually don't work. There are plenty of discussions about this here in the community, as well as a knowledgebase article.

Good luck!
