G070 programming issue?

[sg1]

Hi,

Have a code that modifies the option bytes on G0 micro which seems bricks the IC from further programming attempts aka device locks itself.

Did anyone face a similar issue with G070?

What are the solutions to make the programming process robust and avoid bricking of G070?

Pls help.

I'm not aware of of option byte correction code "As a safety mechanism and recommended by ST". Just curious: do you have some pointers on that.

Not recommended by ST ... but a safety mechanism I wanted to have. Sorry for misquoting.

If this is the case, I wouldn't try to refresh the option bytes after initial factory programming. Each erase/program can be potentially harmful if the power breaks down for example.
