Porting FreeRTOS 7 app to a completeley static allocated v9.0 one.

Posted by andreabuffa on October 25, 2017

Hi all,

I'm in charge of porting an application from V7.1.0 to v9 without dynamic allocation.

Porting was very straightforward, but I found out that application wasn't working correctly at runtime.

The reason was the substitution of vSemaphoreCreateBinary with xSemaphoreCreateBinaryStatic.

While the the former is actually a macro that creates the semaphore and 'give' it, the latter just creates the semaphore. Hence an explicit xSemaphoreGive is required.

This is a documented difference between the two - the functions names (even the one without 'static' at the end) are different...
