Re: [ECOS] diference between ecos and redboot

[Chuck McManis <cmcmanis at mcmanis dot com>]

Redboot is an application that knows how to talk to GDB, how to load SRECs, 
and how to talk to various boot "devices" (network, disk, etc.)

ECOS is the name of a set of routines that get compiled into a library 
which provide operating system primitives for use by an application.

Application is a user developed program that does something.

When you build you application you link it to the eCos library. Then you 
have Redboot load it into memory for you and to start it. Once it is 
started, if it doesn't "crash", Redboot never runs again. If it does 
"crash" it invokes the gdb stubs that are in Redboot and waits to be debugged.

Unlike Linux, or UNIX, or Windows - eCos has no command shell, file system, 
or window system. It is an _embedded_ OS where you generally either don't 
need those things, or you want a simple scaled down version, just enough to 
support your application.
