How to derive out to SWD in a 32pin Nucleo

Post by mjb » Sun Jan 21, 2018 10:23 pm

With Nucleo, I can derive the ST-Lint to a external STM32 MCU through SWD.

By example, In a Nucleo-F446ZE I can communicate to a external MCU, in my case a F373 on board, pulling out the two jumpers of the CN2, and connecting SWD correctly. This is easy to test than who is the target when connect with the ST-link Utility.

My question is, how to do the same with a Nucleo-F432KC, a 32pin Nucleo.
the SWD connector placement is possible but I do not know how to derive out to the SWD connected MCU.

Thanks

I wonder if it is possible.
Seems no solder bridges to isolate the SWD connected to PA13.
AS CN2 is marked as Reserved, I think it is not really planned to use it like this.
