Nucleo-L432KC as a standalone ST-LINK/V2-1

Is it possible to use Nucleo-L432KC as a standalone ST-LINK? It seems there are no jumpers to enable this function.

Question relating to:

Affordable and flexible platform to ease prototyping using a STM32L432KCU6 microcontroller.

Hi Armelle, according to this doc, apperently it is possible, though I'm still not able to get it to work as a standalone ST-LINK Third feature on page 1. "On-board ST-LINK/V2-1 debugger/programmer with SWD connector: – Selection-mode switch to use the kit as a standalone ST-LINK/V2-1"


Just to make it clear: the feature list of the pdf NUCLEO-XXXXKX (see url above) has been completely changed, e.g. the sentence mentioned above "Selection-mode switch to use the kit as a standalone ST-LINK/V2-1" was deleted. Beside to the MicroUSB there are still 5 holes for a connector CN2, which can also be seen at pg 31 in UM1956: http://www.st.com/resource/en/user_manual/dm00231744.pdf But CN2 just connects to SWDIO, SWCLK, +3V3 and GND, but misses NRST, in addition to that you wouldn't be able to disconnect those lines from the on-board target = there's no (easy) way to use the ST-LINK/V2-1 as a standalone tool. Except you'd desolder the original target MCU from the Nucleo and connect the external one using a bunch of wires...

Conclusion: either buy a real ST-Link or use one of the embedded ST-Link of Nucleo64/144 or Discovery boards.
