One way is to write redboot.bin addresses of the entry points I am looking for in a header file and use them when my application terminates given that redboot code is not over-written by ecos app?

#include <cyg/hal/hal_if.h>             // ROM calling interface

should do it as long as the application doesn't do anything to
upset RedBoot while its running.
