Hello,

I have a NUCLEO-G491Re development board, and I would like to program my external board using the development board's ST-Link. Could you please guide me on how to do that?

Thank you

Welcome @khushbu, to the community!

In some older NUCLEO boards, it was possible to use the included ST-LINK/V2-1 as an independent ST-LINK. With the NUCLEO-G491RE (MB1367) this was no longer provided.

Theoretically, after a cursory glance at the schematics, one could come to the conclusion that by removing SB40, SB41 and possibly other jumper/solder bridges, one could lead out the port of the ST-LINK/V3E. However, it is already difficult with the T_NRST signal, as it is permanently connected to the target STM32 and JP3 separates T_NRST from the ST-LINK. All in all, the effort involved is too great for a conversion of the NUCLEO-G491RE to be worthwhile.

Does it answer your question?

Regards
