J'ai pu créer une image Android pour mon Development Board en appliquant mon patch personnalisé au code AOSP. Les fichiers binaires générés (Say Version 1) fonctionnaient correctement. J'ai fait quelques changements à mon patch, construit la dernière image (Say Version 2). Cela fonctionne aussi bien.Erreur lors de la génération du package OTA incrémentiel Android
J'ai target_files respectifs pour ces versions en exécutant la commande dist
make dist
Ce qui a fonctionné
Lorsque je tente de générer package ota supplémentaire sur ma machine Linux (disons PC-1), le fichier ota.zip a été généré et fonctionne correctement.

Ce qui ne fonctionnait:
La même chose quand essayé dans un autre PC Linux (autre que PC-1), il y a une dépendance erreur faisant échouer mon script.
