Pca10028 not functioning

Newbie

Hello, I was trying to load code in pca10028 and I started getting error as "No cortex M Sw device found". It was working properly but later it started showing me this error. I read the solutions provided on devzone and tried to recover and erase by command nrfjprog --eraseall --family NRF51 nrfjprog --recover --family NRF51 But was unsuccessful. I tried reinstalling the JLINK drivers but was not successful. I am attaching the screenshot of the command line output as well as from nrfgo studio. Thanks, Shailav error1nordic.PNG error2nordic.PNG

    Hi,

    1. Does the device show up in Device Manager on your computer? Please try to connect and disconnect the kit a few times. It might show up with unexpected names.
    2. Have you tried to connect it to a differeent computer? If this work it is nothing wrong with the kit, but it might be a driver issue.
    3. Have you tried a different USB cable? Faulty cables are surprisingly often the issue.

    Hi, I could make it work now. I changed the firmware through bootloader mode. Appreciate your efforts. Thanks, Shailav
