In heap_1 from FreeRTOS v9.00, why there is
if( configSUPPORTDYNAMICALLOCATION == 0 )
#error This file must not be used if configSUPPORT_DYNAMIC_ALLOCATION is 0
and heap_1 is used for Static allocation?
Ps : In 8.01 the declaration above is not declared !!
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.
