The test program 'tm_basic' already does exactly what you are asking 
for.  Building & running it is quite simple.  Here's how I do it on my 
Linux development system:

  % ecosconfig new ipaq
  % ecosconfig tree
  % make
  % make -C kernel/current tests TESTS=tests/tm_basic

This would create a "standard" configuration of eCos on the iPAQ (you 
pick your target and put that name here).  Then it builds the eCos 
kernel and finally the test program 'tm_basic'.  To run it, you can
use GDB:

  % arm-elf-gdb -nw install/tests/kernel/current/tests/tm_basic
  (gdb) tar rem /dev/ttyS0
  (gdb) load
  (gdb) c
