How many threads I can create.

Posted by psilva on April 29, 2009
Hi.

My application has aproximately 8 thread and it is running ok, but if I put the 9th thread it hangs.

Has freertos a variable to configure the total threads that I can create?

Best regards.

Do you have enough RAM to hold all the threads stacks? Have you checked xTaskCreate return value?

No you can continue to create tasks until you run out of heap RAM. Which memory file are you using? Heap_1 and heap_2 are sized using configTOTAL_HEAP_SIZE in FreeRTOSConfig.h.

I am using heap_2, and all of you are right, I decreased the amount of stack to the new thread and it was created without a problem. So my problem is not enough memory.

Thak you all.

Paulo
