Sorry for late reply.
Thank you for the pages, I have found them out earlier, but I don’t think that @SinoVOIP should simply rely on comunity. Thanks to BPI M3 I have moved to ATMEGA chips and found out, that for my „projects“ they are enough. The only thing I am using BPI is media and backup server and there I only need linux with few services running and of course PMP, but thanks to community I get all I need, if I had to rely on @SinoVOIP I would be really disappointed.
I only wanted to show @SinoVOIP, that I appreciate your help to the people here on forums, when they are playing dead bug, maybe if they hear it from more people, they might try to do something...
I have finally found purpose for my M3 I will install Ubuntu as they show it is working and will give it to my boss to use it for 3D printer as print server it is not the best usage, but it will be better than have it as paperweight...
