All the EGL_BADALLOC failures that user have been reporting turn out to be a bug in opkg: http://groups.google.com/group/opkg-devel/browse_thread/thread/741d18b0ef31435e# Opkg decides to relink symlinks to the wrong files. As a workaround we check the symlink during every bootup and fix it if needed. Signed-off-by: Koen Kooi <koen@dominion.thruhere.net> Signed-off-by: Denys Dmytriyenko <denys@ti.com>
