How to exit nrf51 DK bootloader mode

[John Nguyen]

I try to how if boot/reset while power up the board and the LED5 is blinking but when I unpluged the cable and plug it again. The LED doesn't turn on any more. And the computer doesn't recognize the board. I still can access the Bootloader mode. So. How to really exit this mode and go back to normal. Thanks

Have you taken a look at this Devzone case yet?

Hello All,

I have also facing same issue as mentioned above.

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.

Please help me out.

Provide your input on this issue.

Thanks

Rohit

Did you try flashing the J-Link interface MCU FW to your device like mentioned in the link I sent?
