I think I've answered a similar question last week. Pls. see this thread: https://lists.yoctoproject.org/pipermail/yocto/2012-May/008625.htmlsimilar question was answ Regards Andrea _______________________________________________ yocto mailing list [email protected] https://lists.yoctoproject.org/listinfo/yocto
