    Do you have a copy of CCS installed? If so, can you try connecting to the target with CCS and try erasing flash from there?

    Thanks

    No, that error is likely not because of your XDS100v2 debug probe.

    If possible, I would recommend installing CCS since it will be easier to debug the issue.

    As for the error, I assume UniFlash can connect to the device (please confirm). Hence perhaps the device is indeed locked. Please see some of the troubleshooting tips in the article below:
