Hi Priyanka,
I prefer the following "soft" solution

1. Connect the J-Link-OB target to PC
2. Start J-Link Commander
3. execute the command
J-Link > msddisable
4. Quit J-Link Commander

In order to restore the MSD functionality, the command is 'msdenable'

Hi Gabriele,

You could disconnect the Interface MCU from the power domain. But you could also disable the USB lines between the USB port and the J-Link device, but this might leave the USB lines in an undefined state. Do you want to power only the nRF chip on the DK? That is possible by changing the SW10 (switch) on the DK to nRF Only.

Regards,

Priyanka
