The development environment is provided as a virtual disk (to be used by a VirtualBox virtual machine) which you can download from this page:
Important
Compute the MD5SUM value of the zip file you downloaded and compare it to the golden one you find in the download page.
Uncompress the file, and you will get a .vdi file that is our virtual disk image. The environment contains the SDK for all the boards provided by Architech, Pengwyn included.
For being able to use it, you first need to install VirtualBox (version 4.2.10 or higher). You can get VirtualBox installer from here:
https://www.virtualbox.org/wiki/Downloads
Download the version that suits your host operating system. You need to download and install the Extension Pack as well.
Important
Make sure that the extension pack has the same version of VirtualBox.
Install the software with all the default options.
We need to setup a port forwarding rule to let you (later) use the virtual machine as a local repository of packages.
Note
The virtual machine must be off
Building an entire system from the ground up is a business that can take up to several hours. To improve the performances of the overall build process, you can, if your computer has enough resources, assign more than one processor to the virtual machine.
Note
The virtual machine must be off
If you changed the number of processors, you might want to consider reading the guides on how to speedup the build process for Poky and HOB.
