Thanks. What's the 5th (VDD <->VTG) for? I don't have the VTG on my board.

Hi,

You can use one of the Debug output headers and make the following connections to your target (easiest from P20 if you have Arduino type jumper cables and connectors): 1. GND <--> GND, 2. SWCLK <<->SWCLK, 3. SWDIO <--> SWDIO, 4. VDD <--> VCC (supply target with voltage from DK to ensure same voltage level). 5. VDD <-->VTG
