Can't get out of Reset mode.

[Craig Hoffman]

I entered Reset mode and got a blinking led. I want to exit this mode but when I unplug and reconnect USB, led does not light and port does not show.

There must be a simple way to exit reset mode so I can continue with development.

thanks in advance for any suggestions.

This is for the nRF52-DK

Hi, 

If you hold the reset pin while you turn the power on, does the board show up as a "BOOTLOADER" drive on your PC? In that case, you can try to re-program the J-link FW by copying J-Link-OB-SAM3U128-V2-NordicSemi-170724.bin to the BOOTLOADER drive, then power-cycle the board. It should show up as "Jlink" on subsequent boot if everything is working.
