The only link between them is the EL/IX compatibility levels ( http://sources.redhat.com/elix/ ) to allow *API* level compatiblity between full-blown Linux and smaller operating systems, e.g. eCos, uClinux, etc. by subsetting the API. > And finaaly I have this big question : What is the difference, which OS I > could better use ? > > Is somebody have some answers to this ? It very much depends on the application you want to use. ucLinux is closer to the Linux API, although a lot of that depends on the C library used. eCos is more flexible, and configurable and has the potential to be much smaller. There's probably more device driver support for ucLinux than is in eCos. I'm not a uclinux expert though :-). Jifl -- Red Hat, Rustat House, Clifton Road, Cambridge, UK.
