Hi ,

I am using the NRF5340DK board and i just plugged the board into my computer and the led 5 on the board is blinking fast and continuously and i cannot see the board anymore in the VSCODE. I have tried changing 3 cables and yes they are data cables not power cables but still does not work , any solutions to this problem ?

Hello Abhijit, based on the forum i checked the voltages on Figure 1 of this power supply info page of the board, below is what i am reading using a multimeter: 

USB IF MCU = 5.11 V , VIN = 3.43 , USB NR5340 =5.12 V

All of the positions of switches are in correct places: Flow Control = ON , nrf Power Source = VDD, nrf = Default and Vext --> nrf = Off

The board was working before and was programmable and no changes were made to the hardware , below are pics of my board below:
