Somebody want to explain the difference between these to me? I'm sure I'm not the only person wondering what's the differences between them...
Also curious. I may have to put Yocto on a card and see what I get, but I'm curious about it. Is it ready to boot and, if so, what does it come with?
Linaro-Ubuntu is an ARM-centric Linux distribution based on the Ubuntu core (which has been almost exclusively x86 until recently). Yocto is a system of packaging, primarily for embedded systems. It is largely processor agnostic, having support for dozens of processors and hundreds of boards. You can do embedded with Linaro-Ubuntu and you can do a GUI with Yocto, but the other way around would probably be easier and more effective. The Ubuntu system would allow you to do development for the system locally, on the same system where the code runs, while the Yocto system would be much more about cross-compiling on a different machine to prepare an image and modules for the UDOO. The choice you make would depend on what you intend to do with the board.
