CCS/EVMK2H: Trying to place heap in DDR3 section. BIOS 6.46, XDC 3.32.

Part Number: EVMK2H

Tool/software: Code Composer Studio

Edited cfg file with

BIOS.heapSize = 2097152;
BIOS.heapSection = "DDR3";
BIOS.heapTrackEnabled = true;

Heap is not placed in DDR3, though. So large mallocs fail.

    Hi Bruce,

    I've forwarded your query to the software experts. Their feedback should be posted here.

    Try the following to  configure heap to DDR:

    var heapMemParams = new HeapMem.Params();
heapMemParams.size = 0x8000000;
heapMemParams.sectionName = "systemHeap";
Program.global.heap0 = HeapMem.create(heapMemParams);
Memory.defaultHeapInstance = Program.global.heap0;

BIOS.heapSize = 2097152;
BIOS.heapSection = "systemHeap";
BIOS.heapTrackEnabled = true;

Program.sectMap["systemHeap"]     = "DDR3";

    Hope this helps. Let us know if this resolves your issue.

    Regards,

    Rahul

    Actually, this worked, except for the fact that the BIOS specifications caused errors. When I commented those out, everything worked as expected:

    var heapMemParams = new HeapMem.Params();
    heapMemParams.size = 32*1024*1024; //0x8000000;
    heapMemParams.sectionName = "systemHeap";
    Program.global.heap0 = HeapMem.create(heapMemParams);
    Memory.defaultHeapInstance = Program.global.heap0;
    //BIOS.heapSize = 32*1024*1024;
    //BIOS.heapSection = "systemHeap";
    //BIOS.heapTrackEnabled = true;
    Program.sectMap["systemHeap"] = "DDR3";

    Thanks,
    Bruce
