Hi, I want to use the stlink part on Nucleo 32 board to write program to a external STM32L432KC board, via SWCLK and SWDIO, can it be achieved ? If so how will be the process ? 

I noticed the SWD CN2 Header reserved on the board, but I do not know how to use it. You did not reserved the selection 0 Ohm resistor or jumper. But I do think you leave it alive for some use ? I checked with oscilloscope, when I download program to the MCU, no wave form.



Thank you for any body who can help me !
