Are there any tutorials for how to set up a dev environment for these boxes, where to get sources/drivers/config, modification as necessary and build (like real basic from scratch)? I have some programming experience and compiling software is something I'm familiar with in both linux and windows but where to get started building a linux kernel and rootfs for an amlogic tvbox is beyond me. The nearest I've probably come is when installing/bootstrapping Arch Linux on x86 and I'm aware that's not even close.
I have ha a S802 M8 box for years and have very much preferred and enjoyed LibreELEC to the factory android firmware. As the original maintainer of these builds/images is no longer supporting some of the boxes anymore (thank you for all your work in the past), how can the community pick up and continue?
