Hi Gao Si,
I think you need to be a little more specific. It is hard to help with only this little information. What board are you using? exactly what tools do you flash with? etc.Regards,/rygelxvi2014-02-26 07:38 AM

I suspect that's the OP's POINT. I would look at what options and write protect settings have been applied to the part. Consider using the ST-LINK utilities? Or what you might have done to the part prior to this issue. Connect using 9600 8E1 (Even Parity) Try using the command line version, it might provide additional information.
