NRF5340 DK Cannot be recognized

[Neo Yang]

My NRF5340 DK evaluation board suddenly stopped being recognized by the computer. The LED5 doesn't light up, and there is no JLINK device in the computer's device manager. Is the firmware lost? How can we solve this problem?

Hello, are you able to test with another USB cable to exclude issue with cable? Have you removed the jumper on nRF Current Measurement (P22)?

Kind regards,
