After about 2 days effort, I got my pinebook64 functional. Fedora 30 does not quite work out of the box. I thought about writing an article to maybe save someone a lot of time, but I can see two drawbacks:
1) don't want to seem to be selling a product 2) the product in question will be obsolete next year, with a new SoC no less creating an entirely new set of problems. :-)
So maybe I should just put it on my blog.
