HeapBufMP_open crashing core0 in simulator

Kevin Alden

Other Parts Discussed in Thread: SYSBIOS

I am trying to get working code to run in the 6472 simulator and have run into a problem with IPC. I have a program running in core0 and core 2. The both start up fine, but when core2 gets to "HeapBufMP_open("MQHeap", &heap_handle);", core0 suddenly jumps to abort().

Digging deeper into HeapBufMP, it looks like when my core2 task gets to INameServerRemote_get in line 341 of NameServer.c, core2 hangs and core0 dies. Core2 will continue to run the idle task. The exact error output I see in the core0 debug console is the following:

ti.sdo.ipc.family.c647x.Interrupt: line 237: assertion failure: A_internal: An internal error has occurred

xdc.runtime.Error.raise: terminating execution

ti.sysbios.gates.GateMutex: line 114: assertion failure: A_badContext: bad calling context. See GateMutex API doc for details.

xdc.runtime.Error.raise: terminating execution

I looked up the GateMutex and found some people recommending System.SupportProxy = SysMin; instead of SysStd in my .cfg file. I made this change and it had no impact.

This code works in hardware, so any clues as to why NameServer would crash core0 on the simulator would be helpful.

Hi Kevin,

Which version of CCS, BIOS & IPC are you using? Could you attach your application to this thread?

Thanks,

Shreyas

CCS 4.2.1.00004

BIOS 6.31.04.27

IPC 1.22.03.23

I'll try to provide the important parts.

This is the code core0 executes:

HeapBufMP_Params_init(&heap_buf_params);
   heap_buf_params.regionId       = 0;
   heap_buf_params.name           = "MQHeap";
   heap_buf_params.numBlocks      = 8;
   heap_buf_params.blockSize      = sizeof(BRONCO_MQMessage_s);
   heap_handle = HeapBufMP_create(&heap_buf_params);    
   if(heap_handle == NULL)
   {
      System_printf("HeapBufMP_create failed\n" );
   }

   // register the heap with message queue
   MessageQ_registerHeap((IHeap_Handle)heap_handle, 0);

   // create the local queue - listeners create queues
   sync_sem_handle = SyncSem_create(NULL, NULL);
   MessageQ_Params_init(&to_Core0_MQ_params);
   to_Core0_MQ_params.synchronizer = SyncSem_Handle_upCast(sync_sem_handle); 
   to_Core0_MQ_handle = MessageQ_create("ToCore0Queue", &to_Core0_MQ_params);    
   if(to_Core0_MQ_handle == NULL)
   {
      System_printf("MessageQ_create failed for ToCore0Queue\n" );
   };

   while(1)
   {
      status = MessageQ_get(to_Core0_MQ_handle, (MessageQ_Msg*)&to_Core0_MQ_msg_ptr, MessageQ_FOREVER);

......

Core 0 then blocks on MessageQ_get.

When core 2 starts up, The first thing it does is try to open the heap with

   do {
      status = HeapBufMP_open("MQHeap", &heap_handle);
   } while (status < 0);
the first call to HeapBufMP_open causes the problem.




Both cores successfully call Ipc_start and BIOS_start before the above task code is run.

OK well I am foolish. I was loading my core2 image onto the wrong core. Everything works now

HI,Kevin:

I meet the same problem as yours,in my project,core0 send message Q to core1.some code is below:

core0 task:

{

·······························

HeapBufMP_Params_init(&heapBufParams);
heapBufParams.regionId = 0;
heapBufParams.name = HEAP_NAME;
heapBufParams.numBlocks = 1;
heapBufParams.blockSize = sizeof(MessageQ_MsgHeader);
heapHandle = HeapBufMP_create(&heapBufParams);

/* Register this heap with MessageQ */
MessageQ_registerHeap((IHeap_Handle)heapHandle, HEAPID);

·····················

}

core1 task:

{

··············

do
{
status = HeapBufMP_open(HEAP_NAME, &heapHandle);
} while (status < 0);

``````````````````

}

the problem is that core1 can't open the heap,want to ask what should I notice before I call the HeapBufMP_open?

Thank you very much!
