we are currently working on such project with a full c application under GPLv2 call linupdate + barebox that will support secure boot platform too such as STB Best Regards, J. > == Contractor Candidates == > Arnout Vandecappelle (Essensium/Mind) > > == Comments == > > > [[Category:Project proposals 2013]] > > > > _______________________________________________ > Celinux-dev mailing list > Celinux-dev@lists.celinuxforum.org > https://lists.celinuxforum.org/mailman/listinfo/celinux-dev _______________________________________________ Celinux-dev mailing list Celinux-dev@lists.celinuxforum.org https://lists.celinuxforum.org/mailman/listinfo/celinux-dev
