DA14681 custom broad jlink problem, please help

I am doing a new broad using 14681, but I encounter some problem about jlink connectivity, my jlink cannot detect the 14681 in my custom broad, but the same circuit is working with my 14580 broad, is there are any different about 14681 pin needed to connect to jlink? any other pin need to connect to jlink other than SWDIO and SWCLK?
I include the circuit design and highlighted the SWDIO and SWCLK for you, thank you.

Hi andoridfm2013,

There is no need for additional pins in order to operate the debug interface, SWDIO and SWCLK should be enough, i suppose that this is connection issue.

Thanks MT_dialog
