Thanks, but my target are these steps for kernel building - similar like this:
Native Edison kernel compile successful, kernel hangs without error
I don't use the Yocto image, it's not my thing and i switched to ubilinux (although that's everyones personal taste).
I think i understand why Intel decides for Yocto. But there are a lot of developers who want to stay at best practiced distributions, Debian (ubilinux) is one of them.
