Need a small "HOWTO" connect an ST-LINK to the board for debugging #22

I'd like to do some dev/debugging on the board, and own an ST-Link V2, but am not sure what pins I should use to connect (did the mod to update the FW using an USB/UART converter, and know it's not the same pins). Which ones should I use ?

You use SWDIO, GND, SWCLK and 3.3V on the stlink and connect them to their counterparts on the DSO's Pin set J3 with the big "SWD" label (left side of the main pcb).
