We are developing support for this board from scratch, based on modern kernel. There are just a little work here and there, by different people, some things are the same as on older, some not. It costs a lot of time at this stage. Perhaps we should provide images with stock closed loader and private kernel? That works at least the same as stock and now certainly works better then mainline based images ... but its a dead end support path. I tried to boot that kernel with modern u-boot ... which would be some good mid path, but I already lost two afternoons on that and got nowhere. Which could be used better. Perhaps spending with family
Our images are not done, which is why we label them WIP. They work or not. If they don't, we can't afford to left our jobs and/or spent afternoons to make them work. Which we usually do, when support is matured and we often (due too lots of investment into knowing how things works) knows why things bread down. And repair broken images.
