You first need to build eCos for real applications.
ecosconfig new eb55 ecosconfig tree make -s
What ends up in the install directory is what you need for building applications. You will find all the include files the application needs, the library containing eCos, the linker file etc.
You can also build the eCos tests
make -s tests
They will then be placed into the install/tests directory tree. The following page shows you have you can download the test and run it.

Once you have that working try an hello world:

You download and run this in the same way.
