nRF52-DK mbed update problem

Steve H

I've just tried to update the mbed firmware on an nRF52-DK to version 0219, and have hit some problems. Firstly, after dragging the .bin file into the Bootloader drive, my Windows 10 PC bluescreened. I managed to update the DK on another Windows 10 PC. Secondly, I can no longer see the Bootloader drive on my PC.

The same thing happened on two nRF52-DK boards.

Any suggestions gratefully received!

    Hi.

    • Does your kit show up in the device manager? With device manager open, can you plug the kit out and then back in again and see if any new devices show up at all? It might not show up as "JLink CDC .... " as it should.
    • Are you able to try a different computer?
    • A lot of similar cases have turned out to be due to bad USB cables. Can you try a different one?

    EDIT: I didn't notice what you were saying about different computers. But to clarify: Are you saying that your kit works on just one out of two Win 10 computers?
