heap creating syslink alloc failure

Bendney Yu

i wrote a g729 codec app, then i had opened codec engine and configure params -- stack size and heap size . i was testing how many handle(dec enc) can be created, but it create failure in 64 handle. i try to change config params, but still can't solve it, anybody had this problem?

You don't say what configuration you tried changing to no effect...

There is a Codec Engine configuration parameter that should help here. The following is a snippet from the Codec Engine examples' common config file <codec_engine>/examples/ti/sdo/ce/examples/buildutils/remote.cfg:
var common = xdc.loadCapsule('ti/sdo/ce/examples/buildutils/common_sys.cfg')
;
var Processor = xdc.useModule('ti.sdo.ce.ipc.dsplink.Processor');

    /* first set module defaults ... */
    Processor.heapId = common.MessageQ_heapMap["Ipc"];
    Processor.sharedRegionId = common.SharedRegion_map["Ipc"];

    /* ... then add per-processor settings */
    var coreComm = {};
    coreComm.numMsgs = 64;
    coreComm.msgSize = 4 * 1024;
    coreComm.heapId = common.MessageQ_heapMap["Ipc"];
    coreComm.userCreatedHeap = false;
    coreComm.sharedRegionId = common.SharedRegion_map["Ipc"];
    if (platform.match("TI814X") || platform.match("TI816X") ||
            platform.match("DM8148") || platform.match("DM8168")) {
        Processor.coreComm.$add(coreComm);
        Processor.coreComm.$add(coreComm);
        Processor.coreComm.$add(coreComm);
        Processor.coreComm.$add(coreComm);
    }
    else {
        Processor.coreComm.$add(coreComm);
        Processor.coreComm.$add(coreComm);
    }

Note the coreComm.numMsgs=64, this is most likely what you would need to increase in order to create more instances.
