[Nate920]

My nRF 9160 DK is being detect by my computer. And my computer detects that the J-Link driver is connect. But the nRF 52840 is not appearing in file explorer. I'm not sure what to do

Is it appearing in Device Manager ?

Has this particular board ever worked before ?

Have checked basics like cables, a different USB port, etc ?

The only the J-Link driver appears in Device Manager

The board was working yesterday

I have tried using another cable and a different USB port

Hi

Just to be clear, is this an nRF52840 DK or the onboard nRF52840 on the nRF91 DK you are talking about?

You can try to re-download the MCU firmware onto the DK, by downloading it from here and dragging the .bin file into the J-Link driver folder.

Best regards,
