Re: Reading "User data storage option bytes"?

Can you just read and write to these locations, or does a page of flash ( or similar ) need to be unlocked first

Re: Protecting Bootloader from being Corrupted

Like Prolific did for clones? :shock: Possibly I know that one of the JLink updates seem to have bricked the clones. But I seems to get random bricking after using them for a while. I presumed this was basically the same thing, but until @dannyf mentioned it, I thought perhaps it was only me that h...
