Reset Bricked nRF51822 Beacon Kit

rsp5y

Hi,

I've recently bricked my nrF51822 Beacon Kit (www.nordicsemi.com/.../nRF51822-Bluetooth-Smart-Beacon-Kit)

...by uploading some bad firmware. I can no longer program it over the air. I want to reset it back to its factory state. Can't find the documentation to do that on this specific kit, is there a specific procedure?

Thanks!

    Hi @Martin I'm not sure exactly what went wrong but I have the original firmware that was working before I uploaded the bad one. I just bought the cable, can I just connect and flash? Or is there a different procedure?

    Here are the symptoms:

    1. When battery is in (or debugger connected using TC connector cable) no LEDs turn on at all
    2. I am using a ULink2 debugger with Keil uVision5. Before I was just building .hex files and sending them over the air. Now I am trying to flash using the ULINK2 debugger+TC cable and I am getting the error "Flash DOwnload failed - "Cortex-M0"
    3. When I plug in my ULINK2 Debugger and open up nRFGo Studio I see no connected devices and "nRF5x Programming" is greyed out.

    Other than this, my code build fine. I just can't flash the beacon kit anymore...any suggestions?

    Thanks for your help
