6) Initialisation de la configuration :

[~/RASPBERRYPI/BSP/poky (dora)] ➔ source oe-init-build-env raspberryPiBuild/
...
### Shell environment set up for builds. ###
You can now run 'bitbake '
Common targets are:
    core-image-minimal
    core-image-sato
    meta-toolchain
    meta-toolchain-sdk
    adt-installer
    meta-ide-support
You can also run generated qemu images with a command like 'runqemu qemux86'
