No, you don't need to cut anything. On PCA10040 you connect vdd to pin 1 of P19. SWDIO and SWDCLK accordingly. It is just standard 10-pin swd connector.

edit. Jorgen was faster, his answer is more detailed :)

Hi,

The debug out port is described here. You need to connect SWCLK, SWDIO, VTG, and GND DETECT. In addition you need to power the external board. You do not need to cut anything, the OB J-Link will detect the exteranal board and flash this insted of the chip on the DK.

If you have som trouble getting this to work, try searching the other threads here at DevZone. There is a lot of questions and answers about this.

Best regards,

Jørgen
