Hello,
I am still learning the basics of ecos. I hope to get
the big picture right. Please do not laugh if I am
deadly wrong.
It seems to me that ecos is NOT meant to be a general
interactive operating system, like linux. The
distinction between the "OS" and "application"
seems blurred. I got the impression that we may
create a "hello world" program that does nothing but
printing "hello world" after power-on a system. In
order to print, this "application" needs to contain
all the stuff needed for handling IO and initializing
the system. ecos is nothing more than a library that
allows "applications" to do OS work. One major
advantage is that the application contains OS supports
only when needed.
How to run X on ecos? It doesn't seem trivial to me.
Running an MPEG player on ecos looks like a big job.
Could you mount NFS? run Netscape? I guess ecos is
not meant to be a software layer for general
interactive systems. While running Linux on a palm
pilot makes sense, running ecos does not.
Is this understanding right? Am I missing the big
picture?
Your comments would be greatly appreciated.
