STM8 Option byte problems

Just another question ...

I presume that there is a high possibility that the ''Error while reading option bytes'' error is caused by wrong option byte settings (not complemneted correctly).

The answer as I understand is to overwrite these bytes using STVP.

It would seem,however, that STVP never starts writing the Option Bytes.

It looks like the option bytes are always read first before a write is done ...

and since an error occured while reading the writing phase never starts.

Is this correct? Would there be a way to circumvent the reading phase?

Regards

Louis

Hi, more than 14 years later...same problem, I solved it by ST Programmer menu : Edit > Fill area (CTL+F) fill with 0 Whole address space. Then all option bytes and the program that rewrites wrong option bytes are deleted.
