MSP430F2619: How to generate code coverage report

Hello,

I have brought this thread to the attention of the compiler experts. They will be able to assist further.

Thanks

I presume you fixed ...

#10247-D creating output section ".ppdata" without a SECTIONS specification

Please try to run a simple program that only performs ...

    puts("Does this string get printed?");

What happens?  If it doesn't work, then try some of these Tips for using printf.

Thanks and regards,

Yes I was able to get the .pdat file, .prf and csv file. But the .csv file shows a frequency of 0 for everything. When i attempt to build with the analyze configuration it fails. The debugger fails as well. I tried putting

    puts("Does this string get printed?");

in my code and was able to see it as an entry in the csv when i attempt to build the analyze configuration. But the frequency is 0.In the .csv everything is 0. In the collect configuration when i try puts or printf i do not see it print to the console.  

I also tried the code by itself (attempting to print to console) and nothing. prints. in my code i can physically see the evaluation board led lightup so i can confirm the code is working/blinking the led.

Please create a new program, entirely separate from the current one, where all of the code is ...

#include <stdio.h>

int main()
{
    puts("Does this string get printed?");
    return 0;
}    

When it works correctly, that string appears in the Console view.  If that does not happen, then please try the Tips for using printf.

Thanks and regards,

I was able to get it to print to console by changing the heap and stack size to 300. I then set my collect and analyze configurations heap and stack size to 300 and reran with my original code (blink led, _TI_start_pprof_collection(); and  _TI_stop_pprof_collection(); called) and still saw the .csv with frequency of 0 for every entry (the entries match the code).

Here's the code that i have

#include <stdio.h>
#include <msp430.h>

volatile unsigned int i;
volatile unsigned long j = 0;

int main(void)
{


//    WDTCTL = WDTPW + WDTHOLD;                 // Stop WDT
//
//    puts("Does this string get printed?");
//    printf("hello world");
//    return 0;

  _TI_start_pprof_collection();

  WDTCTL = WDTPW + WDTHOLD;                 // Stop WDT

  P5DIR |= 0x10;                            // P5.4= output direction
  P5SEL |= 0x10;                            // P5.4= MCLK option select
  P1DIR |= 0x01;                            // P1.0 = output direction
  //P1DIR |= 0x02;                            // P1.1 = output direction

  BCSCTL1 &= ~XT2OFF;                       // Activate XT2 high freq xtal
  BCSCTL3 |= XT2S_2;                        // 3   16MHz crystal or resonator
  do
  {
    IFG1 &= ~OFIFG;                         // Clear OSCFault flag
    for (i = 0xFF; i > 0; i--);             // Time for flag to set
  }
  while (IFG1 & OFIFG);                     // OSCFault flag still set?

  BCSCTL2 |= SELM_2;                        // MCLK = XT2 HF XTAL (safe)

  P1OUT |= 0x01;                          // P1.1 = 1

  //initalize variable
  int loop_count = 0;

  for (;;)                                  // Infinite loop
  {
    for(j = 0xFFFFF; j > 0; j--);

    //P1OUT |= 0x02;                          // P1.1 = 1
    P1OUT ^= 0x01;                         // P1.1 = 0
    //P1OUT &= ~0x02;                         // P1.1 = 0

    //break out of for loop after 5 times
    if (loop_count == 5)
    {
        break;
    }

    loop_count = loop_count + 1;

  }

  //stop code coverage data collection
  _TI_stop_pprof_collection();

    return 0;
}

Please make the stack and heap as large as you can.  While I cannot guarantee it resolves the problem, it is easy to try.

Please use the linker map file to determine where the section .ppdata is allocated.  Inspect that memory range before and after you execute code.  Does anything change?

Thanks and regards,
