Tickless implementation for semaphore in EFM32

Posted by rgokul55555 on December 23, 2013

In my project we are using semaphore, in which we will handle 2 cases. Case1 : Semaphore available within 30Sec Case2 : Timeout. We are facing problem in Case2 implementation We will wait for a semaphore to be available within 30 Sec, if not we will call a function. For saving power we are trying to use to tickless implementation. During waiting for semaphore, when we checked the xExpectedIdleTime in the function vPortSuppressTicksAndSleep, we found the value we are getting about 2,3,3 etc( Single digit values) The value what we expected is 30000, we are not getting the value

We are running the Oscillator with the frequency of 28MHz and Tick freq of 1000Hz. SysTick and Osc Freq are same

We are using OpenRTOS - V7.5.0

You seem to have accidentally created two identical threads, I have already made a suggestion in the other thread...however if you are using OpenRTOS then you should really be submitting a support ticket to WITTENSTEIN rather than using the forum.
