Bon, j'ai profité d'une journée OFF pour bricoler l'ONU (FS 20-BPI), et ça refonctionne !
Donc de mon côté, j'ai du renseigner tous les paramètres et remettre la variable sfp_a2_info.
Voici mon fw_printenv :

Il faut bien vérifier que la variable soit complètement renseignée à l'aide de cet utilitaire :
