On va faire du custom (Partie 2)

Après avoir compiler nos différents éléments, nous allons maintenant les insérer sur une carte SD. avant cela, nous allons la formater suivant le tutoriel fourni sur le wiki de raspberry pi. Il suffit simplement de suivre le tutoriel à une petite modification près. Au lieu de formater la partition linux au format Ext3, nous allons la formater au format Ext4.

ensuite, décompressez les deux archives boot.tar.gz et rootfs.tar.gz trouvées dans le dossier de buildroot output/images, dans respectivement, les partitions boot (FAT32 LBA) et rootfs (EXT4) créées précédemment.
A noter que l'extraction de l'archive rootfs doit se faire avec les droits super utilisateurs.

# tar xzf output/images/boot.tar.gz -C /media/FAT32_PARTITION
# sudo tar xzf output/images/rootfs.tar.gz -C /media/EXT4_PARTITION

ensuite démonter la carte SD et insérer la sur la carte raspberry pi.

# sudo umount /media/FAT32_PARTITION
# sudo umount /media/EXT4_PARTITION

Finalement après avoir ouvert une console série, et branché la raspberry pi, voici les traces de démarrage :
