Svar: Howto make Mycontroller sd-card friendly? (Highly experimental!!)
Hi, I went a different route - I purchased a hardened SD-card with static wear levelling built-in.
That way I get a robust system and I do not have to meddle with all this ram based file system trickery.
It is a nice and easy alternative to those, who do not wish to get in with the command line.
