Yocto Quick Start

This tutorial has the main objective of generating and runnning a yocto image for arm on qemu.

Use Git to clone Poky repo using the apropriate version branch)
$ git clone -b sumo git://git.yoctoproject.org/poky.git
Build Your Image
- Initialize the build env
  $ source oe-init-build-env
- Modify your build/conf/local.conf file
  - Set your machine to MACHINE = "qemuarm"
  - Set the package manager to deb PACKAGE_CLASSES ?= "package_deb"
  - Set the SSTate Mirrors to save time in the builds.
```
    SSTATE_MIRRORS = "\
    file://.* http://sstate.yoctoproject.org/dev/PATH;downloadfilename=PATH \n \
    file://.* http://sstate.yoctoproject.org/2.4/PATH;downloadfilename=PATH \n \
    file://.* http://sstate.yoctoproject.org/2.5/PATH;downloadfilename=PATH \n \"
```
  - Build the image minimal $ bitbake -k core-image-minimal or the graphical sato with $ bitbake -k core-image-sato
    
    Common targets are:
    - core-image-minimal (no X server)
    - core-image-sato (X server with SATO)
    - meta-toolchain (??)
    - meta-ide-support (package for ensuring the build directory contains all appropriate toolchain packages for using an IDE) check also Tips and Tricks
Run the image on qemu.
$ runqemu qemuarm
