Hello. I'm using ARM cortex-R5(TI) CCS 6.0, FreeRTOS 8.1.2.

xSemaphoreTake(*pxSemaphore, 0) goes exception error in my project.

I tried configure options in FreeRTOSConfig.h for using sempahore.. but it still has an error.

Could you give me some tips to use semaphoretake func?

Did you create the semaphore first? Please post the code that creates then takes the semaphore.

I am curious why you have the * in front of pxSemaphore? The FreeRTOS functions take handles (which are internally pointers), but you shouldn't be referencing them yourself.

Sorry, it was not error in xSemaphoreTake(). it works well now. Can I delete this post?
