Re: A89: Writing to Flash ROM
All info needed are out there already. But if you make code available you will
have a lot of morons who know how too use cut'n'paste trying too look cool and
evil and dangerous by creating virii and stuff.
I think the way it is now is quite sufficient. Now you need at least some
determiination and knowledge to make something like that. It doesn't guarantee
anything, but at least it keeps the complete morons away.
