I am using the CORTEX-R4_TI_CCS5 port with v8.0.0 FreeRTOS. This is Demo for cortex R4 processors and the TMS570 series. The port uses heap_4.c and appears to never initialize the heap. When the first call to pvPortMalloc is called, the pvReturn var is never accessed. Obviously I am missing something. Any help would be appreciated.
