Recently my program often die with "ti.sysbios.family.c64p.Exception: line 256: E_exceptionMax: pc = 0xc0112df4, sp = 0xc0115110." when it run for a long time.
I have check the hwi stack size and task stack size. Both are free space available.
I have no experience debug this sort of error. Can someone help me out? thx
Sorry for mention that, Yordan Kovachev. I am using Process SDK RTOS OMAPL138 LCDK 4.00.00.04 on my custom C6746 board.
Recently I add system stack size in my app.cfg
The problem occur more often. Even when i start my app application.
I guess this is caused by memory issue. this is piece of my app.cfg
/*
** Create a Heap.
*/
var HeapMem = xdc.useModule('ti.sysbios.heaps.HeapMem');
var heapMemParams = new HeapMem.Params();
heapMemParams.size = 0x20000;
heapMemParams.sectionName = "systemHeap";
Program.global.heap0 = HeapMem.create(heapMemParams);
var heapMem0Params = new HeapMem.Params();
heapMem0Params.instance.name = "MyHeap";
heapMem0Params.size = 91392;
heapMem0Params.align = 8;
heapMem0Params.sectionName = "MyHeap";
Program.global.MyHeap = HeapMem.create(heapMem0Params);
var heapMem1Params = new HeapMem.Params();
heapMem1Params.instance.name = "TcpHeap";
heapMem1Params.size = 15232;
heapMem1Params.sectionName = "TcpHeap";
Program.global.TcpHeap = HeapMem.create(heapMem1Params);
/* This is the default memory heap. */
Memory.defaultHeapInstance = Program.global.heap0;

I am not familar with low level memory issue.
Can someone help me?
