Redboot is just an eCos application. The test cases are eCos
applications. If vmware can run Redboot, it should be able to run eCos
applications.

The same way you run the test cases. The hello world example shows you
how to link your application to eCos.

I would suggest you first start with a clean, unmodified tree. Get the
test cases to run. You might find tm_basic interesting since it
performs timing measurements of kernel operations.

Only once you have unmodified eCos working, then start with your
modifications.
