Hi, There are a core dump when using uac_auth with from_restore_mode = none. I think the problem is this: If from_restore_mode is NONE the load_tm_api isn't called in init function (file uac.c). load_tm_api(&uac_tmb) When uac_auth is used it invokes uac_tmb.t_gett that isn't set (file auth.c). t = uac_tmb.t_gett(); BR.
