Avant tout , je trouve un fonctionnement curieux. Si apres tout un tas de manip on arrive a un blocage au boot apres la ligne 'flash..' et que rien n'y fait ( enfin, je n'ai pas trouvé,  plusieurs u-boot,script.bin etc), une chose extraordinaire se passe après un certain temps sans rien faire sur la carte .. le boot refonctionne. franchement c'est tres chiant.

Je mets en dessous la trace d'u-boot revenue la miraculeusement après une nuit de sommeil.

à noter que les autre u-boot que j'avais n'implémentait pas ext4load, ce qui explique juste le blocage.

Bref 

recup d'une wheezy : http://cubian.org/downloads/

après boot login username et password : cubie
<code>
sudo ~/nandinstall/install.sh
ou
apt-get install cubian-nandinstall
sudo cubian-nandinstall
</code>


Add GPG key
<code>
wget -O - http://packages.cubian.org/cubian.gpg.key 
apt-key add -
</code>
ajouter <code> deb http://packages.cubian.org/ wheezy main </code>
puis apt-get update
