Well at least before they started "Boot to Qt w/ Android", working on boot to Qt implied polishing the Yocto Qt5 layer or writing another one from scratch. They obviously did some work on that and it's a pity that nothing have been given back to the community. That was my point. > Or someone else could do the maintaining of the Qt 5 layer in Yocto.

No, Qt doesn't depend on Digia, but Digia depends on Qt! When you look at their "Qt Enterprise Embedded", it's Qt, QtCreator, QtSimulator, GNU, Linux, Android, .... with a pinch of "Enterprise plug-in's and add-on's" all well packed together. > Besides, IIRC the Boot to Qt project was trying to use the Android base layer > because that's the best BSP that most silicon vendors provide. Notably, the > vendors not participating in Yocto. They might have switched to Android (Well, apparently not really [1], Yocto is used both for targeting Android and "Pure" Embedded Linux), but AFAIK you can boot to Qt in less than 0.5s with a bare embedded Linux (using Yocto or similar), whereas it takes 10 times longer with Android. Having said all these, Digia has its own business model, maybe I was expecting Digia to behave much like Nokia, my mistake.
