The error message in itself does not give any hint as to what is actually wrong - only that the tool is having difficulty accessing the part.
Actions associated with protection and low power modes can affect this.
First recommend step always is to erase the part using the "CrossCore Serial Flash Programmer" which will eliminate any reason associated with the previously downloaded code.
