nRF52-DK board stop working

[dilbert168]

I have been using the nRF52-DK for while and it been good.

But when I accidental hold the "BOOT/RESET" button, the board now stop working.  only LEDs is blinking (per sec)

When I power cycle it, the nRF programmer does not detect the board.

How could I put the board back to normal operation ?

Hi,

Could you confirm whether your SW6 (switch 6) is pointing to DEFAULT? If not, then kindly put it to DEFAULT.

Even then if it's not working, could you confirm with the steps mentioned here?

Regards,

Priyanka
