Heap_1 static & dynamic allocation problemPosted by bachadamin on March 22, 2017 Hello Guys In heap_1 from FreeRTOS v9.00, why there is if( configSUPPORTDYNAMICALLOCATION == 0 )
endif
and heap_1 is used for Static allocation? Ps : In 8.01 the declaration above is not declared !! Heap_1 static & dynamic allocation problemPosted by rtel on March 22, 2017 The array from which heap1 allocates its memory is statically allocated at compile time, but heap1 is still used to provide dynamic memory allocation to FreeRTOS applications. If configSUPPORTDYNAMICALLOCATION is set to 0 then you have specified that dynamic memory allocation must not be used, so attempting to compile any of the example dynamic memory allocation schemes will fail. This #error statements were put in at the request of people creating safety critical systems to ensure dynamic memory allocation could not be used, even by accident.
