STM32CubeIDE freeRTOS semaphore creation issue

[MarcinGajewski]

Hi,

I have a problem during creation of Semaphore in STM32CubeIDE. When I create a semaphore (dynamic or static) and add it to register view then.... nothing happens. I discovered that issue when in fact this mutex behaves as it wouldn't be created ever (taking it, results in  time out). In exactly same way, I do create other semaphores/mutex in the system and all fine. I was making tests and observed:

• dynamic/static creation has no effect
• heap is sufficient, creation in dynamic mode successfully allocates memory for it
• the order or creation matters, just like there would be a lock on max 6 sempahores. When I move the semaphore to initialize it first, it works, but the still the last semaphre suffers. 

Any ideas?

Thanks

Marcin

There is limitation in freeRTOS of queue in registry, limited in my case to 8 (I have had already 2 standard queues), so just 6 places left, not allowing 7th to be created.

 

Issue sorted.
