Disable SEGGER J-Link OB Debugger

[ran]

Hi 

Is there a way to disable the on-board  SEGGER J-Link ? ( jumpers ? ) 

The reason is that in our design we will use an external J-Link ( no space for OB ) , so we want to make sure we can connect to external J-Link ?

Hi,

The solder bridge on the nRF52 DK can be cut to disable the power for the interface MCU. The overview for the solder bridge can be found here. the list of devices that are supported by J-Link can be found here.

Can I set "sw6" on DK to "nRF Only' ? and then connect wires to SWD gpio ?

My last reply was for the nRF52 DK. Yes, you can toggle the SW 6 or unplug the USB cable to J2 to disconnect the interface MCU for the nRF52840 DK.
