Hi Patrick,

Thanks for your reply. I am having issue with J-Link. When I tried to connect, I got the error 'No emulators connected via USB'. I have submitted a ticket (No emulators connected via USB on nRF51 and nRF52) for it.

The J-Link EDU Mini does not have a virtual COM port. This causes issues when using functions of nrfjprog that require the COM port but it works fine for flashing firmware and debugging.

So you can see the j-link device in windowsn device manger? and you can see a com port being mounted (j-link cdc UART port)? Are you sure you do not have any other applications that could be using the device?
