Over the last three days I've set up a virtual machine (VirtualBox) running Ubuntu 14.04LTS, pulled the Yocto/Poky source, and created the build environment using the instructions listed at PokyBuild < Linux4SAM < TWiki. All of this went surprisingly well with no hitches. However, I did find that the build went a lot faster once I allowed the virtual machine to use eight cores instead of one! I created all three images as well as Atmel Poky QT-embedded SDK.
From there I went on to compile a simple "Hello World" application using the cross compiler from above. However at this point, I'm unsure how to get this newly created application into one of the images to transfer over to the target. That will be my goal for tomorrow.
Here's a list of some links I found helpful during this process:
