nRF5340 DK not detecting in Windows10

[Sreejith Sundh]

Hi,

I am completely new with the development kit nRF5340, I have plugged in the USB and turn it ON, the status after that as follows,

- LED5 is blinking continuesly

- LED1, 2, 3, 4 are blinking one by one (in periodic order)

- Power Source in VDD

- SW10 is set to OFF and SW6 is set to right

I have followed all the instruction based on the previous chat on tis topic, nRF5340 DK - Windows not detecting DK - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)

but not yet solved.

I appreciate greatly for you help.

Thanks and Regards,

Sreejith

Hey Sreejith!

I am looking into it. Have you tried a different USB port and/or USB cable btw? That is surprisingly often the culprit.

Best regards,

Hi Elfving,

Many thanks for your response and for your time. Yes I have tried many ports (many times), and with different PCs and with different USB cables. But not detected.

Could you install nRF Command Line tools, and run:

nrfjprog -i

Best regards,

Yes I have installed command line tool and added path in to the environmental variable. Tried the command 'nrfjprog -i', nothing happened,

I am sorry for the delayed response, I could not see any ids for serial numbers of all the debuggers connected to the computer. Is this problem with my PC (I mean some required serial drivers)? Thanks Elfving for your guidance.
