Logiciel

Concernant le logiciel, la carte échantillon a été livrée avec le système Raspbian préinstallé sur carte SD (apparemment préparée en Allemagne). Rien de plus facile que de raccorder la carte à une console puisque, contrairement au RPi, le BPi dispose d'un port de débogage auquel vous pouvez relier un convertisseur série-USB. Le journal de démarrage complet est proposé à la fin de cet article.

Selon le site BPi GitBook, les images relatives aux systèmes d’exploitation Android et Ubuntu devraient être disponibles, mais les liens m’ont renvoyé le message d’erreur « 404 - Not Found ». Ce problème devrait être résolu lorsque la carte aura été commercialisée. Le système Linux Tina-IoT d’Allwinner est proposé avec le M2 Ultra, mais rien n'est dit de la manière de l'adapter pour le M2 Berry. Peut-être fonctionne-t-il parfaitement, sans pouvoir en être sûr...

 
banana pi m2 berry + rpi3 back sides
À noter l'encombrement plus important du connecteur pour carte SD sur le BPi M2 Berry (à gauche) par rapport à celui du RPi (à droite).

Conclusion

Le Banana Pi BPI-M2 Berry s’adresse aux utilisateurs du RPi. Présenté après le RPi3, nous pouvions nous attendre à des performances similaires. En réalité, nous avons affaire à un RPi2 v1.0 avec Wi-Fi, Bluetooth 4.0 et interface SATA. Le Berry étant proposé à un prix similaire à celui du RPi3, l'interface SATA pourrait bien être la seule raison de le préférer à un vrai RPi (3 ou 2).

Il n'a pas été possible d'insérer le BPi M2 Berry dans mon boîtier de test RPi à cause des dimensions de l'adaptateur pour carte SD. Pour autant, la carte échantillon est une pré-série, et ce problème devrait être corrigé avant la commercialisation. Quelques découpages viendront à bout de ce problème. En revanche, l'incompatibilité des connecteurs LCD et caméra avec les ouvertures standard du boîtier est plus problématique. Ils ont probablement été conservés pour garantir l'adaptation à d'autres cartes BPi, mais au détriment de la promesse de compatibilité avec la gamme RPi.

Journal de démarrage Banana Pi M2 Berry

Nous insérons ici le journal de démarrage de la carte pour les experts Linux qui en tireront toutes sortes d'informations extrêmement utiles. Pour se connecter, il suffit d'indiquer le nom d'utilisateur « pi » ou « root » et le mot de passe par défaut « bananapi ».
