Hi, I am having issues in connecting nRF 5340 DK to PC. The issue is surprising and I don't know how it happened. Just showed up the other time I plugged in the board and it's repeating everytime. When I touch the metal cover in hand, it works. Sort of noise/crosstalk issue? Any suggestions/help? You don't have permission to edit metadata of this video.

Fictitious nRF board! JLink connectivity error.

Hi,

I am having issues in connecting nRF 5340 DK to PC. The issue is surprising and I don't know how it happened. Just showed up the other time I plugged in the board and it's repeating everytime. When I touch the metal cover in hand, it works. Sort of noise/crosstalk issue?

Any suggestions/help?

Is it only when you touch ground? Or anything metal on the board? What happens if you touch the same point with a wooden stick or a plastic pen?

Yes, only that particular switche's metal and not anywhere else. Only if it's through the body, works. Insulator no, grounding with conductor no, grounding with 1M resistor no!
Quite surprising, it's still the same.
