CreateStatic & heap allocation problem

Posted by bachadamin on March 23, 2017

Hello, After creation of a task or queue with createstatic, I verify my heap free space but I found that it still the same as I define it in freertosconfig.h ? I'm using heap 1 and I set the static allocation to 1 and freertos v 9.00 So could you tell me where those tasks are created exacetly ?

CreateStatic & heap allocation problem

Posted by rtel on March 23, 2017

If you use the 'CreateStatic' version then you are explicitly using statically allocated memory, by which I mean, memory allocated by the compiler at compile time. That is distinct from dynamically allocated memory, which is allocated from the heap at run time.

See the description of the puxStackBuffer and pxTaskBuffer parameters on the following documentation page: http://www.freertos.org/xTaskCreateStatic.html
