Hi Manua
1. "internal" means that it was developed&tested internally by nxp development team for public usage,
also as was answered by LP, i.MX Yocto Project Team Lead [09.06.2014 10:50]:
When we do a release we always do it on the last stable Yocto Project release.
2. "not yocto compatible" was said at time of writing that post, when only ltib linux versions
were provided by nxp. Later yocto replaced it.
>could you provide a couple of use cases where is better to use one over the other?
One can use both, seems official release is better for beginners since better documented
so one knows what expect and what tested :
"Documentation"
