At least if you *really* need netboot functionality you have something working to base your work on. - I do not feel netbooting is not usefull, it can help tremendously when you can't easily swap boot media, imagine MMC soldered on board... but in this particular case, I mean developing for Orange Pi One board, it is only *convenience* thing, not hard *requirement* I hope I clarified my position with this and no flame war will arise :) Actually I have an idea where should I (or someone more motivated than I in this functionality) begin looking for solution of this problem, it is a bit deeper in uboot I would like to go to for now. Do we agree it is still worth publishing/submitting to ports tree even with some missing functionality?

I am just lazy, sometimes, to think too hard, because, you know, thinking suffers :) and not everyone is comfortable with it. I hope we will continue working on this board so it could be used for as many purposes as anyone can think of. Thanks for all the help from the team. Regards, Milan
