Hello,

In v2.86, it seems that with uCOSII, you need to call yourself the function OSTmrSignal() as :

- It post the OSTmrSemSignal semaphore which is the condition to execute the OSTmr_Task() task.

- No other kernel function post the OSTmrSemSignal semaphore

You can check that in the \altera\91\nios2eds\components\micrium_uc_osii\UCOSII\src\os_tmr.c file

As far as i've seen, the uCOSII documentation seems a bit weak for this part.

However It is quite new feature as it as been introduced in V2.81 in think.

Maybe it was too early ;)
