Hi, As a beginner, I'm trying to have CDC J-Link Uart port work with my laptop. I'm using nRF52 board. When connecting the board to my laptop (windows 10), it displays the following in device manager: Actually, I cannot use any terminal to open this COM port. I have downloaded the latest "J-Link software and document pack". Please tell me how to fix this problem? Thanks a lot.
