STlinkV3 usability of the STM32G4 Nucleo-32 board (MB1430)

Hello

I may have misunderstood:

By cutting some SBs off

and soldering on CN2

the embedded STLinkv3 can be used externally ? meaning on other targets/boards ?

CN2 is for programming the ST-LINK's IC

Thank you, I thaught: too easy !

Do you know "just on top of head" if that is possible ? (using stlinkV3 standalone)

In the mean time, I'll dig deeper in the schematics/docs .

Regards

I don't think the Nucleo-32 is accommodative of this.

You could perhaps remove the G4 and access PA13/PA14 and PB3 pins via header.

The Nucleo-64 (G474) might be more accommodating, but isn't snap-off as the older designs were.

May I know the reasons to use on board ST link for external debug?

1) It is a pure question : stingy geek i am

2) having an stlinkv3 technically under the hand, why not use it :)

3) i am going right now to check out its price :) (an stlinkv3)

regards

See https://community.st.com/s/question/0D53W00000OmiV6SAJ/nucleoh732zg-has-strange-new-stlink-part, near the bottom there is simple program to disable the MCU on the Nucleo. For H723 but changes to a G4 should be fairly simple.

"3) i am going right now to check out its price "

And availability!

As you said you have one at hand, so use it.
