PCD: Trouble with RTOS
PostPosted: Sun Jun 06, 2010 11:15 am     Reply with quote

I'm new from CCS compiler and from SourceBoost C++(rtos).
Now I 've make some test like this :
Code:

#include <33FJ256GP710.h>

#DEVICE ADC=10
#fuses HS,PR_PLL    // Crystal HS, 4xPLL
#fuses NOIESO       // No 2-speed Start Up
#fuses NOJTAG       // No JTAG
#fuses NOPROTECT    // No Memory Protection
#fuses NOWDT        // No WatchDog Timer
#fuses NODEBUG      // Debug Mode.

#use delay(clock=40M, oscillator=8M)

#use rs232(UART2, STREAM=serial_debug, baud=9600, bits=8)

#include "lcd_ex16.c"
#include "init_timer1.c"
#include "isr_rtc.c"
#include "init_ADC.c"

unsigned char seconds = 0;      #locate seconds = 0x900
unsigned char minutes = 0;      #locate minutes = 0x902
unsigned char hours = 0;       #locate hours   = 0x904
unsigned int adc_value = 0;       #locate adc_value = 0x906

int1 toggle_led = 0;

#int_timer1 level=4
void isr(void)
{
   // RTC interrupt handler
   toggle_led ^= 0x01;
   if(toggle_led)
      output_high(PIN_A0);
   else
      output_low(PIN_A0);
   isr_rtc();               // refresh LCD RTC time
   set_timer1(0x8000);
}
//==========================

void main()
{
   // main program
   //
   Init_Timer1();

   init_ADC();

   lcd_init();
   home_clr();
   printf(lcd_puts,"\fRTC 00:00.00");
   printf(lcd_puts,"\nADC 0.00 ");
   delay_ms(1000);
   output_float(PIN_A0);
   
   //loop
   while(1)
   {
      adc_value = read_adc();
      lcd_gotoxy(5,2);
      printf(lcd_puts,"%3.2f v.",adc_volts(adc_value));
      delay_ms(100);
   }
}

Omit any other files , this work fine without problem.
If i try to use rtos in this mode :
Code:

#include <33FJ256GP710.h>

#DEVICE ADC=10
#fuses HS,PR_PLL    // Crystal HS, 4xPLL
#fuses NOIESO       // No 2-speed Start Up
#fuses NOJTAG       // No JTAG
#fuses NOPROTECT    // No Memory Protection
#fuses NOWDT        // No WatchDog Timer
#fuses NODEBUG      // Debug Mode.

#use delay(clock=32M, oscillator=8M)

#use rs232(UART2, STREAM=serial_debug, baud=9600, bits=8)

#use rtos(timer=0,minor_cycle=100ms)

#include "lcd_ex16.c"
#include "init_timer1.c"
#include "isr_rtc.c"
#include "init_ADC.c"

unsigned char seconds = 0;      #locate seconds = 0x900
unsigned char minutes = 0;      #locate minutes = 0x902
unsigned char hours = 0;       #locate hours   = 0x904

unsigned int adc_value = 0;       #locate adc_value = 0x906

int1 toggle_led = 0;

#task(rate=100ms,max=100ms)
void task1();

#int_timer1 level=4
void isr(void)
{
   // RTC interrupt handler
   toggle_led ^= 0x01;
   if(toggle_led)
      output_high(PIN_A0);
   else
      output_low(PIN_A0);
   isr_rtc();
   set_timer1(0x8000);
}
//==========================

void task1()
{
      adc_value = read_adc();
      lcd_gotoxy(5,2);
      printf(lcd_puts,"%3.2f v.",adc_volts(adc_value));
}
void main()
{
   // main program
   //
   Init_Timer1();

   init_ADC();

   lcd_init();
   home_clr();
   printf(lcd_puts,"\fRTC 00:00.00");
   printf(lcd_puts,"\nADC 0.00 ");
   delay_ms(1000);
   output_float(PIN_A0);
   
   rtos_run();
   //loop
}

The debugger (I maybe) have a stack overflow or other and stop it resetting CPU.
What's wrong?
Thanks for your help.

What's your compiler version ? According to this thread, there were
problems with the RTOS in the PCD compiler, in mid-August 2009.
This would be around version 4.096 of the compiler.
http://www.ccsinfo.com/forum/viewtopic.php?t=39677

I don't have the PCD compiler, so I can't give any more help than this.

CCS C Compiler version 4.1.0.8 PCD is the current that I use.
Best regards.

You should check what's the exact reset cause. Stack overflow doesn't sound unlikely, because PCD has a (too) low default stack assignment. Stack overflows have been reported e.g. with float arithmetic. You may want to try with an increased stack size.

Is the same with this sample code !!!!
Code:

#include <33FJ256GP710.h>

#DEVICE ADC=10
#fuses HS,PR_PLL    // Crystal HS, 4xPLL
#fuses NOIESO       // No 2-speed Start Up
#fuses NOJTAG       // No JTAG
#fuses NOPROTECT    // No Memory Protection
#fuses NOWDT        // No WatchDog Timer
#fuses NODEBUG      // Debug Mode.

#use delay(clock=40M, oscillator=8M)
#use rs232(UART1, STREAM=serial_debug, baud=9600, bits=8)

#use rtos(timer=0, minor_cycle=100ms)

#task(rate=1000ms, max=100ms)
void first_task()
{
   printf("task 1\n\r");
}

#task(rate=500ms,max=100ms)
void second_task()
{
   printf("task 2\n\r");
}

#task(rate=100ms,max=100ms)
void third_task()
{
   printf("task 3\n\r");
}

// MAIN
void main()
{
   rtos_run();
}


there would have to put any switch (?) in a linker compiler setting before use RTOS????

You can try, if increasing the stack changes anything
Code:
#build(stack = 256)

But there may be other reset causes (e.g. address error trap) as well. Because all exceptions are unhandled by default, you won't see but a trap conflict in the reset register. You need to install respective trap interrupts to identify specific execptions.

Nothing to do. Please see me how trap interrupts in previous sample code.Thank's.

I use :
Explorer16 demo board with Mplab 8.50 + ICD2
this is the build result:
Code:

This, the disassembly listing :

Sorry... but I'm very demoralized. CCS does not respond to my requests and on the internet I only found the same problem with other people but no solution .... I Try in every way.

Thanks again if anyone can help me. Would it be possible to use a different RTOS with CCS? And if so, what would be the best?

Hi,
I have the same problem on a PIC24f.
When the program try to execute rtos_run(); there are reset.

The restart_cause() is 15 which means RESTART_TRAP_CONFLICT.

I wrote one month ago to ccs support they said :

We have some one running some tests now on the PIC24 RTOS to find out
if there are any outstanding issues. Check back next week.


And nothing . I use PCD 4.107 version.

Yes, that can be expected in case of an unhandled address error or stack overflow. It would be important to know which one of both has occured. I previously suggested to increase the stack as a first measure. Did you try?

For further reading, refer to the below threads:
http://www.ccsinfo.com/forum/viewtopic.php?t=36479
http://www.ccsinfo.com/forum/viewtopic.php?t=40083

Address error trap can be caused by bad pointer operations in user code, but mostly indicates a PCD bug, according to my experience. There have been various cases with previous PCD releases, and I expect some trapdoors still to remain.

Yes CCS RTOS works on PIC18f ( 18f4523 for my application )
It was very easy to use. It was my 1st application with CCS RTOS.
best regards
