CygMon is a ROM monitor. As far as you are concerned, it is what you
program into ROM so that you can load your application. When the
application is run, CygMon loses control. Although in some cases, it
"co-operates" with the program to allow the program to be debugged. eCos is
capable of this.

CygMon is only there to be programmed into flash/ROM. You don't link with
it. It is an application in its own right.

Perhaps you are getting the concept confused with having to link your
program differently if you are using it with a board running CygMon in ROM.
While this doesn't always happen, for GNUPro, for example, you sometimes
have to use a different linker script (specified with -Tcygmon.ld on the
link command line) to indicate that this is what your program is doing.
This isn't the same as linking with cygmon itself.

BTW, remember to CC the list. Don't e-mail me directly please.
