NRF52 development kit does not power up

Biketap

Hello,

I have been using the development kit for more than a month when after one flashing, the LED 5 on the board started blinking at one second intervals and the board froze. After unplugging from the USB and plugging it back again the board does not power up anymore.

I tried the battery, without the USB, but same behavior was shown.

Any help?

I am using KEIL.

    • Hello All,

      I  cannot exit from nrf52 DK bootloader mode. It is not going to normal mode.

      How i can solve this problem?

      It is working fine previously but now if i plug in / out usb the main LED is not blinking.

      If i pressed reset button several time then in between it is going into bootloader mode by generating new drive as "Bootloader"

      And it is not showing J-link connection also as well as board is not resetting.

      Please help me out if so

      Provide your input on this issue.

      Thanks

      Rohit
