One might think that if this was a perfect world. The reality is that very few people want to spend the time to find and read tutorials/FAQs/documentation. They just come to these forums and expect expert hand holding support for free from people who are volunteering their time. Igor has a lot more important things to be working on to keep Armbian afloat then even responding to posts in these forums. While I don't personally deal with rockchip sbc's, so I can't help you specifically here, as a moderator of these forums, I end up answering the same questions over and over again simply because people expect free support, not a community of people just trying to help. In the spirit of open source the easiest way for someone to contribute to help others is to dig in, learn and then contribute back what they have learned either through these forums, through contributing to the Armbian documentation or through actual code. (I'm mostly writing this, so that Igor doesn't need to take his time to respond, since I want him to be using his time elsewhere)

Are you sure about the math, because if you write a tutorial, even a relatively brief one, covering at least a few points to guide me more than just a few hints, you'll save a lot of work for a lot of people who would otherwise spend hours doing it. 😉

@johlnx Please use paste.armbian.eu, also it seems a bit off-topic Ah I see, you just made a typo and wrote "RK3588" instead of "RK3528".
