CCS/TMS320C6655: Calculate clk cyles using profiling for a code segment of a function

Tool/software: Code Composer Studio

Hi TI

I'm using the Code Composer Studio (v6.2.0) together with XDS200 debugger.

I would like to profile a function to verify how many clk cyles it has been used to run through a loop.

By using the "memory browser" I can identify where the function is located in the external RAM and by using asm-file and lst-file I can identify the code start and stop at the memory.

I really need to have a number of clk cyles it has been taken to run through the code.

My setup:

- The C code:

void CpuLoadTask()
{
  int i; 
  RegisterSystemTask((OS_HTask)TSK_SELF()); 
  while (1) 
  { 
    if (hPerFunc == NULL)
   {
     OS_TaskSleep(OS_SECTOTICK(0.1f) );
   }
  for (i=0 ; i<1000 ; i++)
  {
    ++g_uiCpuLoadDummy;
  }
  ++g_uiCpuLoadCounter;
  }
}

- The asm code when the code is loaded into the memory:

I would like to profile from addr. 0x8017712c - 0x80177178 to see how many clk cycles it take to run through the code segment.

1. From Code Composer studio I've tried to use: "Tools --> Hardware Trace Analyzer -> Function Profiling --> Trace Range --> Start and Stop Addresses -- > Start Address = 0x80177128 --> Stop Address = 0x80177178 --> Start". But there is no usable result from the trace

I've tried as well: 

2. From Code Composer studio I've tried to use: "Tools --> Hardware Trace Analyzer -> Stall Profiling  --> Trace Range --> Start and Stop Addresses -- > Start Address = 0x80177128 --> Stop Address = 0x80177178 --> Start". But there is no usable result from the trace as well

Can you please help with a correct guideline. 

Thanks
