[sbk7]

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,

Could you try nRF command line tool for erasing the board? You can try "nrfjprog --eraseall" command for doing this and try recovering the board using "nrfjprog --recover" command. You can find all the commands in here. You can download the command line tool from here. Please share a screenshot of running this command if this doesn't help. Also check whether your DK is visible in PC(device manager). Also try connecting the board to another PC and see whether it detects the board or not (if possible).

Kind Regards,
