Hi! I have tested programs on three nrf52 DKs before, and when I connect this time, two of them show up and work well on my PC, while the other one just has all four LEDs on, not showing anything on PC, neither in device manager nor nRFgo Studio.
I have tried installing the latest J-link, testing another USB cable, another PC and power supply but it just does not show up on my computer. And the reset button does not work. Is there any solution to this?
Thank you!
