heapMemParams.size = 235*1024*1024; //0xF4240;    /* 1Mb*/                <--------------  modify here to use more than 256M ddr, and demo cannot running into main function
heapMemParams.sectionName = "systemHeap";
Program.global.heap0 = HeapMem.create(heapMemParams);
Memory.defaultHeapInstance = Program.global.heap0;
