Hi,
I suppose that you use LPCXpresso860-Max board and MCUXPresso tools.
In the case, you can connect the J4 usb connector to PC,then delete the *Debug.launch file, which can be generated automatically.
Then click "Debug", the MCUXPresso tools can detect the correct probe you connected, and download.
If you use your own board and true J-Link device from Segger, I am sorry.
If you use LPCXpresso860-Max board and J-Link device from Segger, you have to close JP1, connect the J-Link device to J7.
Hope it can help you
