Programming nrf52 DK board using external j-link

[IndraP]

Hi,

I am trying to program the nRF52 DK with external j-link Base. I am using Debug IN P18 connector and connected the following pins

j-Link base                        nRF52 DK Debug IN P18 Connector

Pin 7            ------->      Pin 2 (SWDIO)

Pin 9           -------->     Pin 4 (SWCLK)

Pin 13        ----------> Pin 6 (SWO)

pin 15          ---------> Pin 10 (RESET)

I am powering the nRF52 DK using coin cell and opened the project in segger studio. When I try to program the board I get error " Failed to connect to target. No idcode detected. Please check connection and target Interface Type."

Can you help me to fix this problem.

I was able to program the development kit with the external j-Link. Seems the issue was with the cable. 

Thanks.
