Please see my note book http://mbed.org/users/kenjiArai/notebook/freertos-on-mbed-board-with-mbed-cloud-ide--never-/

This is too old.
Below is another FreeRTOS on mbed.
http://developer.mbed.org/users/rgrover1/code/FreeRTOS/
I don't know it works well or not.
I have not evaluated it.

kenjiArai	0:d4960fcea8ff	55	* Creates two sets of two tasks. The tasks within a set share a variable, access
kenjiArai	0:d4960fcea8ff	56	* to which is guarded by a semaphore.
kenjiArai	0:d4960fcea8ff	57	*
kenjiArai	0:d4960fcea8ff	58	* Each task starts by attempting to obtain the semaphore. On obtaining a
kenjiArai	0:d4960fcea8ff	59	* semaphore a task checks to ensure that the guarded variable has an expected
kenjiArai	0:d4960fcea8ff	60	* value. It then clears the variable to zero before counting it back up to the
kenjiArai	0:d4960fcea8ff	61	* expected value in increments of 1. After each increment the variable is checked
kenjiArai	0:d4960fcea8ff	62	* to ensure it contains the value to which it was just set. When the starting
kenjiArai	0:d4960fcea8ff	63	* value is again reached the task releases the semaphore giving the other task in
kenjiArai	0:d4960fcea8ff	64	* the set a chance to do exactly the same thing. The starting value is high
kenjiArai	0:d4960fcea8ff	65	* enough to ensure that a tick is likely to occur during the incrementing loop.
kenjiArai	0:d4960fcea8ff	66	*
kenjiArai	0:d4960fcea8ff	67	* An error is flagged if at any time during the process a shared variable is
kenjiArai	0:d4960fcea8ff	68	* found to have a value other than that expected. Such an occurrence would
kenjiArai	0:d4960fcea8ff	69	* suggest an error in the mutual exclusion mechanism by which access to the
kenjiArai	0:d4960fcea8ff	70	* variable is restricted.
kenjiArai	0:d4960fcea8ff	71	*
kenjiArai	0:d4960fcea8ff	72	* The first set of two tasks poll their semaphore. The second set use blocking
